Engine options in a Corvette.

Hey guys I have an 87 Corvette. I have had it for about 9 years now and I have replaced or restored everything on the car. The only thing I haven't done yet is the engine. I am selling off all my other projects, one of which is a big block Camaro. I have thought about keeping the motor and putting it in the Corvette. Yes it would be more work but it would also have a ton of wow factor. The other option is to build a 400 hp small block and just have fun with it. The car is not daily driven so that isn't a concern.
So what would you do? Opinions are welcome. Thanks.

keep the small block and put the eldabrock top end kit 435 hp and put a mini 144 series bloweron it add about 100 hp now u got 535 or more then put 125 shot of nitrous and that light body will fly. we have a 79 corvette with just weilend intake and 670 holly d/p that thing is fast. if you put the big block youll have to change susp. and make the motor fit lot more work.

why not keep the camaro and sell corvette?? just a thought

The swap doesn't scare me. There isn't alot to it. THere is no need to upgrade the suspension as the BB with aluminum heads, intake and water pump only weighs 50-70 LBS more than the SB. The steering box needs to move forward about an inch and a half and the cross member needs to be notched.s armed with that info...

Thanks for the options, this is what I am after.
Mini 144 blower? Is that a carb app.? Isn't my compression ratio to high for that?

i think it is 144 177 have to look it up but it will fit under your stock hood. kit says u can run it on a stock motor, yes its single carb approved. give approx 100 hp or more with better heads. but if u get real serious i would rebuild the motor with forged rods crank and pistons. with a little bit lower c/r . if u have lots of money than buy 4 vavle heads a mild 350 with these heads easily make 500 hp but they cost about 6500 $. the blower info is in jegs online catalog. these combo with the 4 v heads and a shot of nitrous will easy mak 750 hp with good street manners.

I don't think you will fit a blower and a carb under the stock hood. I work with a guy with a 85 vette, 383, replaced the fuel injection with a Holley 750 and a Weiand Stealth, he ended up buying a cowl hood to be able to run any kind of air filter.

Raidmagic -- Corvettes are great, and lots of fun. I think a 400 ci small block (OK, 406) with a great set of AFR heads, a good street roller cam, and a holley or demon on top would do a great job of giving it more go. Adding a big block will complicate future service (that's an assumption on my part), add unnecessary weight, and supply just maybe enough torque to blow out the differential. Building a 450-500 HP streetable, normally aspirated smallblock is not a big challenge today, what with all the tried and true combinations that are out there. And with good 2 valve heads, it can be built for the price of the 4 valve heads alone (or thereabouts). It'd be gobs o' fun! I think the hardest part would be finding a good 400 ci block to start with. Of course, there are those aftermarket Bill Mitchell type 454 small blocks . . . . .

Let us know what you decide.

BTW -- are headers available for the big block swap, or would you go custom on them?

Pat

What is in it now? Do you still have the TPI setup? If so your in my ballpark and we can talk about how to make it scream . My roomate has an 85 Corvette. Basically the same car except you use an updated computer.

Aluminum block, heads...everything. Go for Whipple or other centrifugal blower with injection and have something thats super light, very powerful and will help to make that vett handle.....that would be pretty easy to do and would make one nasty do all vett.....I got a buddy with a 2001 Mustang done up pretty much with that formula. Sucka rips and is very stealthy.

I personally think that (unless this will be a strip-only ride) there is no reason to use a big block. One of the vette's greatest attributes is its light weight handling capabilities and a near 50/50 weight distribution.

To me, the only recipe that fits is a 1hp/ci small block. Keep the handling, save the independent rear from grenading, and save the headaches.

Too many times we hot rodders misplace our intentions. Let's not forget that some cars turn corners, too
