I've stated this before, but im going to state it again... a saying from my wife that they use in Russia a lot:
Cheap pays twice
do it right the first time and you wont be doing all over again later...
the other truth:
cheap, reliable, fast..... you can only choose 2. right now you picked cheap and reliable.. but dog slow.

If you want all new GM buy this
http://www.summitracing.com/parts/na...0283/overview/
This
http://www.summitracing.com/parts/na...2586/overview/
and these;
http://www.summitracing.com/parts/nal-12499224
You will have to buy 787 retainers from comp to fit the springs, a vortec intake, gaskets and electric fuel pump and regulator but it should get you 400 HP for well under $3000. 99% new GM, No warrantee.

Or, you can put the same money (or less) into aluminum heads, new roller cam & lifters, and headers w/dual exhaust on your present engine.[/QUOTE]
my only issue with this is years ago I did this to a 350 and basically blew out the rings with in a year and started burning oil like crazy.
My current engine was rebuilt 35k miles ago bored 30 over. I would be afraid of doing the same thing.
I have no Idea of the quality of parts or workmanship.
I do have the receipt from the previous owner but it doesn't list in detail what parts were used.
This is why I'm leaning towards a crate engine. Otherwise I have a feeling I'm going to end up putting 5k into my current engine. But i am guessing at best.
So after reading this I guess im saying my budget including labor to install the engine is 5k or less.

Here's the link to my swap

So far so goo and this engine is VERY strong...
No tearing apart and voiding the warranty, no machining, no re-assembly...just pull old and replace
If not that engine, something similar. I just think it's a great price.

The HP numbers for that 383 are what a 350 with aluminum heads and that same roller cam would be and the tq numbers are close.
I would ask that blueprint company what a 350 set up like the 383 would cost ya. Should be cheaper.

Add 1.6 roller rockers if that is a roller cam .. and you will end up almost at a zz430 which is 430hp and 430tq lifts will be 525 and 528 respectively..Saves ya a few dollars keeps you closer to the 3000.00 upgrade cost

How are you liking you engine? any issues? I'm getting close to pulling the trigger on one of those blueprint engines. From what I can tell i think it's going to fit my needs and budget fairly well. So far my biggest problem is i keep looking at them and going well for another $300 i can get this .. next thing i know im looking at the $4500 engine. lol

That Blueprint 383 sound like it would fit the bill. Good luck with the engine change.

Don't spend money on conveniences. You'll be spending your time and effort instead. Don't spend money on shiny things. The stock valave covers work just fine. Roller tipped rockers are a waste of money. They don't eliminate enough friction to make them worth it. (roller trunions are a different story) Shop around for good deals. Things like that.Scott

Cam dynamics cam, bored .030", roller rockers, headers, edlebrouck perfect carb and intake.....405hp on the dyno. I took the factory matching engine out and replaced it with this one. I had built it for someone that changed their plans. I am not sure what I am going to do with the original yet. It's completely apart so I have lots of options.

We've helped many corvette owners on here rebuild their engines and you sound like you have some experience. With the 383 kits on the market today and the price they are selling for can't be beat!
Between machine work and rotating assembly you will only be into it for @$1500 add a set of aluminum heads and you'll have a great street burner for @$2500
Or the dirt cheap way to go since you only have 30k for mileage. Pick up a re-ring kit with bearing. Pick up some small chamber heads to bump up compression and match a cam to it! You'll have 300 hp for $1500. Building up a running motor take a lot of risk out of the build and you'll see if anything was compromised over the years on tear down.

Most of us are always asking how do i get more hp. I'm not a mechanic but I know the basics.
When I looked into replacing the camshaft, heads and intake it was going to run at least $2k paying someone to do it.
Tell me why shouldn't buy this 260hp from jegs for 1,500 (free shipping too) change out the cam put factory intake on it and call it good with maybe 275- 280 hp and have a brand new engine from top to bottom?
Is this a decent idea or am I way off base here.
specs for engine
Chevrolet Performance 10067353 GM Goodwrench 350ci Engine
GM Goodwrench 350ci Engine
260HP/350TQ
4-Bolt Main
3-Year/100,000 Mile Warranty
never mind now that i check the website is saying it's not compatible with a 73 vette
