how about a LS swap just did a LS1 t56 ^speed in my 64. love it and runs 172 degrees all day long.

This what I don't understand. Why all that hp when "...the car won't hook up anyway..."? The only thing I can think of telling people you have 565 HP.

Also, I might have missed it, but didn't he say his budget was $7000? You are saying he may need another $5K for reliability of other parts on the car do to usi9ng this engine. And that is if he "does his own work"?

So $12K, not $7, to but put an engine in a car so "the car won't hook up anyway". You lost me on this one my friend.

Tom aka "friend"...I was responding to a previous poster who said he needed $20k to handle that 406...I don't think he really needs to do anything but drop in the 406 and run it...even if it won't fully hook up...thanks, friend...

[QUOTE=MarkC;1589292856]Frank, I was looking at it from a full Resto mod point of view using a stock frame. IMO, I just can't see increasing the hp to nearly double of what he has now and leaving the stock trans, shafts and rear gear that is 50 years old. Once you add a new exhaust ( 3 inch), respectable tires and wheels, disc brakes, control arms, heavier rear gear and shafts I doubt you will have much left out of 20k. Sure you can drop that kind of power in the car and leave every thing else stock but I would never do that. We have an honest difference of opinion.

It appears from your avatar that you are a duck hunter. Where do you hunt? I have hunted ducks in the Northern neck, Eastern Shore, Back Bay and Northeast NC. I have about given it up now, but in my earlier years I truely loved it.

Also, if you do any car shows, you should consider the Williamsburg Corvette Show. It is the best show that I have been to in the state. It is at the Williamsburg Winery around Memorial Day . I would like to meet you.[/QUOT

MarkC - yep I still hunt....mostly up in North Dakota...unbelievable...I grew upon the east coast but never really hunted ducks until I got out of college and by then I was gone.

We should get together for a soda...

You're confusing horsepower with torque. Horsepower is a function of RPM. Not being able to hook up is one of the reasons I like a "screamer" (moderate torque-high horsepower) engine for a midyear, whose design is not really amenable to wide tires without some modifications.

I have a 327 which makes quite a bit more torque than the old 327/300, but as the revs build, it keeps on making torque up beyond 6500 RPM. And that, my friend, is horsepower. About 475 to be exact.

FYI:

Horsepower = [Torque x RPM]/5252
where T is in ft-lbs

MikeM

Denver. Yes the perfect place for a screamer type engine. But never fear, time he tries to shove 565 hp/8000 rpm through his stock exhaust system, he'll lose at least 100 hp of that so maybe he'll be okay.

A mildly modified big inch small block is all we need here.

65tripleblack

Ha, ha, ha!
Now that there's funny!
Just imagine how many doughnuts you can do with a torque monster on a slippery road.
Although a truck motor, the way you like 'em would be helpful for the OP's Corvette once he puts a plow on it!
Ha, ha, ha!

Torque vs HP, A friend who also owns a Machine Shop had a 69 NOVA SS 396 4 speed car. He built a wild 396 for it, it was fast but hard to drive comfortably. His wife would not drive it. Rough Idle, Premium Gas, old school power. He built a new engine, a 540 inch, dropped his compression to 9:1, it would idle like a bone stock 454, ran on regular gas no problem and stomped his best 1/4 mile times he had with the 396. After the change his wife would frequently drive the Nova and enjoyed it. It was a kitten till you stepped on it. Granted he added 144 cubic inches but torque made it go. I know the Nova can fit a little wider tire than a C2.

Sky65

Yes I understood the point of your response. And I guess calling you a friend is not permitted. Too bad. I like having friends and I'm not a bad one but I'll get over it. Done

I guess what I don't understand is why put so much more engine in a car than traction will permit using? I like to spin the tires up on my car. It's fun. But you don't need all that 406 to do it. I'm not trying to be a smart a$$. Serious question. I am trying to understand. Makes no sense to me.

Yeah I guess I was wrong using HP only in my post. I didn't see the torque spec listed. I'm speculating that 406 is in the 500lb/ft torque range. Still a whole bunch more than needed.

Tom,

Ok, I misread your comments as sarcastic...my apologies.

I agree that these cars don't need 565 hp...however, it has nothing to do with need...and for me, if I am going to go though the *** pain of pulling an engine with the intent to replace it because I want more power, then I am going to find something with the most power I can that fits my criteria...I once bought a zz4 and I wasn't happy...I prefer a stroked small or big block for the hassle...I'd do a LS3 if I had the time.

Cheers,

Frank

Sky65

No worries.
Ok. I understand. I guess we come from different places. I am very money conscious. For me to spend 7K on more than you need is a waste of money. That same money could buy plenty of engine and perhaps a 5spd. It would make a real nice driver and I am all about driving them!

An LS3 would be very cool. I wondered if that can be done as a bolt in without body or frame mods?

High RPM screamers are great, but in my limited experience torque rules in regular driving. I like the idea of a 377/383/406. Easy to live with as long as you don't get crazy with a big cam.

That seat of the pant's feeling is great!

I have a ZZ4 fast burn with hot cam kit from GM in one of my cars. A little over 400hp, lots of torque. I have beat the hell out of this motor for 2-3 years and nothing, I mean nothing has gone wrong. No noise or leaks or smoke nothing. I have not talk to or read where anybody is unhappy with the ZZ4, very reliable and tons of torque. No cut wires, mechanical fuel pump, Best of all around 5k.

Have Mark Jones update your 327. It will remain stock but get a complete rebuild, head/intake porting, and a hydraulic roller cam. Take the remaining budget and do a FAST 2.0. In the end you get 400hp, efi, and still have matching numbers.

ChattanoogaJSB

Our own member did this VERY slick install, and notes that it can be done for much less than his $13k on page 4. https://www.corvetteforum.com/forums...project-4.html

Probably a very radical 396. Not a good comparison however.

My 327 is very easy to drive. The roller cam makes 275 ft-lbs torque at 2000 RPM, which is wayyyyy more than the 327/300. The difference is that the torque keeps building to a very flat 375 ft-lb peak between 3000 and 6000 RPM, where it drops off slowly. What that means, is a very drivable car, which can smoke the tires almost as much as a 383, but screams to make 475 HP @ 6554 RPM, and continues to make 450 HP @ 7250 RPM.

What's the difference whether you have 375 ft-lbs or 425 ft lbs torque if you can't keep the tires from spinning?

tebok

Great thread. I would go LS3 in a heart beat, but the additional cost and mods to the frame led to my loss in interest. The last thing I want to do is compromise the ability to return back to the current state of a very original car.

MikeM

Then it might be a good idea to not put a 565 hp engine in a 300 hp car. Don't you think?

tebok

Seems to be working out for my buddy and his 69 Camaro

Westlotorn

Triple Black, your engine sounds great as I have told you before, and you built exactly what you wanted.
My only point is you can build a 400 SBC that drops right in done by a machine shop that pulls like a big dog to 5,800 RPM for less than $4,000, your engine done by a machine shop with parts that are safe at 7,500 RPM would be $8,000 to $12,000.
There is a market and demand for both engines, it is just a matter of how much you want to spend to get exactly what you want.
