New to C3 corvettes should i pull the trigger?

I was just offered a 1975 vette for $4k. It's in ehhhh shape. Belongs to my mechanic's brother.
- seems to be in great mechanical shape
- interior is cracked up in various places but has all parts
- paint job has been redone multiple times and parts of the body look like dried dirt with the top layer of the paint and maybe bondo? cracking up
- It's an automatic

So I know very little about these cars but I'm very tempted to give it a go and see what i can do. So i have a few questions.
1. how difficult is it to convert it to a manual and how cheap could i make that conversion?
2. What the heck is up with the HP numbers on these 350ci engines? 165hp? I don't know much about V8 gas engines but something doesn't sound right there. SMOG is no issue on a '75 here in CA but i'm mostly interested in making it efficient. Good MPG and Good HP, i'd like to find the balance between the two without breaking the bank.
3. I'm assuming fixing whatever is choking the engine and changing to a 5 speed manual would drastically improve the stock MPG? any ideas by how much...roughly?
4. what's up with the fiberglass? are spiderweb cracks pretty common and are they simple to fix? based on how bad these are (even on the doors) i'm guessing they keep coming back or getting worst?
I'm pretty mechanically inclined and have been rebuilding my H1 Hummer for years so i'm no stranger to mechanical work but a 6.5TD H1 is a completely different beast than a 350 Corvette and i wanted to get your expert opinions before jumping in over my head.
Thanks for any advice!

i think that thread actually backfires, the vette looks a lot better now compared to those rust buckets 
I think i passed most of those except the I want a manual and this is an auto. but then again if i had a manual i don't know how long it'd be before i wanted to upgrade to a 5speed to get better mpg. Also i'd love a chrome bumper 69 but there's a pretty HUGE $$$ difference between that an a '75. At least i still get the flat rear window which i prefer.
I did take a look under the car and the frame is pretty much rust free (course it's a southern CA car so that's not too surprising). didn't check the birdcage though. I'll drive by next week and see if i can see anything bad. Car started right up with a pump on the accelorator and engine idled smooth, didn't get to drive it around cause (being in a mechanic shop, it was behind a customer's car that was having it's airbags worked on and they couldn't move it but he said i could drop by anytime later to take it for a spin.
I will still have to make some small repairs using my own hands and it will need a paint job.
If I am lucky, very lucky I will have into it what it is worth!!
1976 and 1975 were not exactly the glamour years for the Corvette and I doubt that 350 will get much better without a cam and heads. Take your 4000.00 and put it on black!!
Lastly, I don't care if I make a penny. I love these cars and that's why I do it.
- it's the last year that doesn't need smog in CA (which is important to me)
- It still has the flat rear window
- and its a pretty inexpensive way to start having fun messing with a vette.
Things I don't like:
- wish it was a stick
- wish it had chrome bumpers front and back
Around here its almost impossible to find vettes in decent shape for under $6-7k much less a manual one older than '72. I'm hoping that with $5k into this one doing most of the work myself I can have a fun road car to drive to work and maybe even take to the local autocross solo weekends?
As for stick, well its Californian, no sticks from there, turbo 350 was a good trans though, and chrome bumpers, well wait until the first moron at your 7-11 backs in to you because he cant see the front of your car and you will be happy about the soft, flexible neoprene bumper.
buy it and enjoy, Dennis.

you want to find a good body car...
Second you want to get it lifted and check the frame for rust, as well as the rear suspension and bushings...
Also the interior is cracked? what's cracked?
and chevy only put two 350's in 75 L48 and L82... If it has an L82, Buy it! but 165hp is wrong... L48 put out about 190 stock, by now it might be lower.
And a conversion will probable be more expensive then you think...
I got my 76 for 7 and some change, it's a 4 speed and no major problems at all..
I would pass by what you have said so far; unless you are looking for a lot of work?
I bought a 74 from a guy down the road from me. Pretty much a target of opportunity. Sounds like it's in similar condition and price as yours. It sat in my garage for a few years after purchase, and I finally have found the motivation to get working on it.
It's a 62K mile car, and he owned it most of its life. It already had a repaint to change the color from white to green when he bought it in the late 70s. And both of the bumpers covers were rotted so bad that when part of the rear fell off, I took them both off.
First, I think you will learn a LOT just by getting it, getting some books and reading, hanging out on the forum, and poking around your car. I've found that it's almost therapeutic to work on it. I don't feel pressured to get a job done, and just work on what I want. When I hit a wall, I stop and think about it and attack it later. I will say, there seems to be no end to what you find that needs attention!
I also am not keeping track of what I'm spending as I work on it. I'm not sure I even want to know! I am fairly certain that by the end, once I have it professionally painted and the interior redone (beyond my abilities), I will be badly upside down in what it's worth versus my investment. I didn't really think about this when I started, and like you I prefer the bumper cars and manual transmission and wish I would have sought out a deal on one that was driveable and closer to done (as I'm not trying to do a full restoration on mine, but make it a driver). Think it would have been cheaper in the long run, and I could be driving it instead of working on it right off. But then, I would miss learning a lot too. Catch 22.
To your specific questions:
1. Not sure - I'm not talented nor adventurous enough to try it. When this car is done, and I'm ready for vette #2, I will get what I want.
2. I'd suggest if you get the car, you drive it like it is for a while and see if it really performs as poorly as you think based on a HP rating. Again, enjoy it, learn about it, and then decide what you want to do to soup it up.
3. Again, I'm not help here. If you want MPG, I'd say you're looking at the wrong car. I'd rather have a 454 in my car, and have it pass everything but a gas station.
4. You may not have a fiberglass problem. The paint on mine seems like it may have been similar to yours in spots. I have taken a razor blade to the back deck of the car, and it was just the paint. Once I got past the green paint, there was no problem. I think you can tell how abused the car is by looking in other areas, and get a good idea if there's really a fiberglass problem.
Good luck! Have fun! And make sure to get pics posted when you get your vette!
and pretty much finished it up (just waiting on getting the seats back from the upholstery guy). I can tell you, would have been WAY cheaper if i had that 30K sitting in the bank and bought what i wanted to end up with, BUT it's nice to say i did it my way as well. Catch 22 is right.Here's a before and after pic. Took 4 years of on/off work, saving pennies, hunting for deals. All the work was done by me (cause i'm too cheap to pay anyone else to do it.



So before i'm even completely done with this one i'm itching for my next project but i'm not looking for another 5 year commitment. The car is driveable as is and I'm hoping to just clean, tinker, and start working on little parts of it as needed, fix any leaks, rebuild the suspension, etc. after working any mechanical gremlins i'd start sanding down through the multiple paint jobs this thing has had, fix and prime the body then just drive it that way for a few months to make sure no cracks start surfacing before paint.
I love non-practical vehicles, purpose built. I was thinking it'd be fun to turn it into something like this, but without the front chrome bumper. The rear bumper looks easy enough to change using a '82 fiberglass one (i know it's not the same but i haven't seen one that looks like a '72).

I was thinking if I eventually plan on trading up to a 5 speed, change the color and modify the interior anyway, then this might be a good canidate for the project. I'd hate to start cutting into a restorable classic. I've painted cars before and done racing stripes. Not professional jobs but they looked beautiful 10 feet away
I'm not sure what to do with the interior but i was thinking of slowly minimizing it and turning it black w/aluminum panels. (BTW I'm a second generation aerospace machinist)Guess i just needed to hear some feedback incase there was something i hadn't thought about before taking the plunge. My main concerns were with the tranny which i guess i'd wait on untill everything else was done and the weird HP rating that popped up when i searched for '75 specs. Sure it's not my preference but it's a lot easier for me to buy a cheap car then slowly sink money into it than saving up and buying something already done (funny, everytime i want to save for a new toy somehow bills increase and the money dissapears
) plus it's easier to sell the wife on a $4000 toy than a $10K toy....bwaaa haa haaa

At 4 or 5 k you can do what ever YOU want to it and not feel guilty about modding a more complete and expensive car. There are even some threads on here where someone is building the rear bumper to mod it to a chrome bumper car since you are wanting one.
Just read, read, read and you'll find tons of info on everything that you want to know in here.

First off -- I believe you're underestimating what it will cost to fix that $5k vette up.
How about if I told you that you should have at least $3 to $5k to spend on it to bring it up to minimum reasonable standards. That's before the whole foray into changing transmissions -- which is a ill-advised notion. This is a Corvette, not a Pick-up truck. To spend what will be $12 by the time you get done -- to have that value scrapped by conversions is anti-productive. So let's say that meant buying the fixer upper for $5 still meant you should have like $8,500 to $10k in your budget (now.. not later.. now). Now that you KNOW you will need spend some $$ to get it into shape question is, do you think you're better off spending $8,500 to $10 on a better condition vette OR are you really truly into fixing this up (paint, mechanicals etc.) ?
So..
1. If your answer is anything along the lines that you don't think you'll need to put $3 to $5 into the $5k Vette, then you are completely unrealistic and probably not ready to buy this car.
2. If you do realize it but don't have that additional money, then you are not ready to buy the vette.
3. If you never thought about it, but have the money then you have a decision to make. With respect to Chrome bumper Vettes, I just saw one on CL the other day in the $9's, $10's, $11's and $12,'s -- all nice.
Save your money and buy the best one you can.
You are NOT repeat NOT (emphasis on the meaning of word NOT) going to get something for nothing. Your friends uncle's mechanic's sisters friend whatever would buy the Vette IF it were that much of a steal.
NOTHING in life is free. If it's too good to be true, it is.
Good Luck
