What kind of corvette engine? Putting a 3rd gen corvette engine wouldn't be much of a sleeper, since vette and fbody L98s are pretty similar. An LS1 or an LT5 would be a different story.

Try the motor swap board.

it's only special if you use the corvette badges along with as many stickers as you can fit on the car. add some glasspack muffler's with craiger ss/t's or keystone classic's and your in dude. (the best corvette engine's come out of van's and old trucks as they seem to be the biggest source for them).

A Vette engine isn't really different from your run-of-the-mill smallblock unless you're talking the LS1 based engines.

A 3.8 or 4.3 intercooled turbo engine would be better project IMO. A little harder to do though.

Sounds like a whole lot of work and money to make a difference over your 305.

Make that LS1 conversion a LOT & LOTS of money. It may be cheaper to buy the whole Corvette instead.

Using an LS1 out of a corvette might wind up being harder than using one out of an f-body, which is easier to find and just as powerful. The C5 uses the drive-by-wire throttle system, which you'd have to convert, and the C5 accessories (alternator, a/c compressor, power steering, etc) may not fit well in the thirdgen engine bay.

Nobody's ever done that, or even thought of it before. You're the very first one. Amazing, the Corvette has been around for almost 50 years now, and nobody has ever done it. Hard to believe. What a great idea. It'll be the baddest thing since "The Fast and the Furious".

Of course, once you realize that (a) the engine in a Corvette is pretty much the same as the engine in any other car, except that it has a few chassis-specific features to make it fit that chassis that aren't needed in any other chassis and make it not fit in another chassis very well; and (b) it will cost you twice as much as the otherwise identical motor that doesn't say "Corvette" on it because a bunch of Vette owners with less sense or mechanical knowledge than most of us and bigger wallets than yours who tore up their motor are out-bidding you, the stars in your eyes that appear when the magic "V" word is invoked will disappear quickly.

Unless you see the car the motor came out of, don't pay one single cent more for a motor that is claimed to be "out of a Corvette". It's the greatest sucker line in all of hot-rodding. It's astounding how many 350s there are out there "from a Vette"; there's probably 4 or 5 times as many of those around as there have ever been Vettes, and their numbers are growing daily. Even if the motor had actually been in a Vette at some time or other during its life, no magical properties will have just miraculously emanated from the fiberglass and mysteriously imbued themselves into the cast iron or aluminum. And if you do in fact get your hands on a motor that is actually the one that came from GM in a Corvette, sell it to one of the more typical Corvette owners as described above, and use the profits to build yourself something better.

It's always funny when the emissions guys look at my TPI and ask "You put a Corvette motor in there, huh?"

Seriously though, the differences in corvette engines and others are simply that vettes had the highest factory hp ratings. This results from cams, heads, intakes, etc, all of which can be done to any engine to either make it either equal (more likely better) than the vette engine. Unless of course you're talking of a certain small block with Lotus and Mercury Marine connections...

I say the heck with a corvette engine. Look at how much it will cost you to put a fuel injected vette engine in your car. Take about 5k and build yourself a mean motor that will put the vette motors to shame. Even better, pick up a TPI and throw a blower on it-- there will be nothing sleepy about your sleeper now.

no offense to the *** of musclecars (the corvette)... BUT I can whoop a bunch of them... well except for the modded ones, and the ZO6, and callaway, and the Lingenfelter, and the ZR1, and the old Stingray, and the experimental one with 32 valves( somewhere in the mid 80's)

would the ls1 out of a firebird/camaro be easier to put in or less expensive. if not the ls1, what's the next fastest engine that can be put in for the least amount of money. i love corvettes too, lol:hail:

Least amount of money? You're not looking at an LS1, then. I sense that you have done zero or no research. Try reading the motor swap board or do a few searches.

And be like any other idiot that spends thousands of dollars so they can have an "LT1" and 30 more HP ? LMAO... Regular SBCs aren't good enough for you people or what ?? This is the same thing as the "corvette engine" deal.

Dude, any garden variety gen 1 350 with flat top pistons, decent heads(ie vortecs, AFRS, or the many others), a cam with decent duration and lift(like the extreme rollers from comp cams), will handle the power of the LS1. And 3000 grand would probably cover the cost.

Infact if your willing to do some labor you can really save some money. I bought a reconditioed L98 short block for around $800. That included the core charge since I didn't have a 350 roller block to turn in. Got a XR269HR cam used off ebay for a little over 100 bucks. They are around 230 brand new. I used 305 416 heads with larger valves and bowls unshrouded for a cost of around 350 bucks. Performer RPM manifold and Q-jet carb. That cost me well under 2000 bucks and I can run with the LT1 cars. I really regret not trying to port the heads myself. I think that would have gotten me in LS1 territory. Or at least close. Point is your better off putting your money in a Gen 1 block set up. Dollar for dollar you will be better off. If you spend 5000 on a gen 1 block you will really be flying. That kind of money could build a really stout 383.

It all depends on what your want and how much you want to spend. I am looking at 330 to 360hp at the wheels on the motor and 430-500 on the gas.
Personally, I'd rather have a V6 Turbo but I didn't find one when I was looking for a motor to replace my 305.

Yeah I guess. I remember seeing a vette with a V6 turbo in it. Personally I'd stick to a "tried and true" SBC. I've got a healthy 400 in it that beats stock Vipers and then some. I'm happy with that and I can't really ask anymore from a N/A daily driver. hehe
