New Guy - Need Help with buying Engine!!
My sister has a 1982 corvette collectors edition and she needs a new engine. I tried buying a crate motor from GMPP through summit racing but they all required carburetors. She wants to keep the cross fire injection so that was out of the question. Wants it as close to stock as possible. The sales rep said it would just be too much work in order to get the motor to run correctly. Can anyone here point me in the right direction. She wanted to order a new engine with the next week. I have not been successful finding an engine that would work with her set up. More horsepower would be great but a stock replacement would also be fine. Any sites??
Thanks in advance
John

Well we got the car towed to a mechanic i know and he said it needed a whole new engine. It was down on two cylinders. He took the valve cover off and I even saw that two cylinders were not operating.
The first time we noticed a problem the car kept on stumbling and stuttering.
Which part do you say is BS? The part about summit racing and the motor not running correctly?
Here is the link to the motor we were going to buy::

If you are interested in keeping the car original, you should pull the engine. Have the original engine disassembled by an engine builder and see if the engine can be rebuilt. I would get several recommendations before choosing a builder. Good machine shops and engine builders are hard to come by so take your time.
You can always buy a short block and have your heads rebuilt if originality is not a problem. You could even buy a long block and use your stock intake manifold to retain the cross fire.

the part about the engine not running correctly with the crossfire system is BS. That engine looks like it would work for your needs... a little low on the HP, but very cost effective.
you may want to talk to your mechanic some more... im curious as to why he would tell you that... he may just want you to get everything through him instead of ordering an engine from summitt.

My sister doesn’t care too much if the serials are matching but she just wants it look stock (cross-fire injection). I don’t know of any good engine builders near me so we are going to play it safe with a crate motor. We'd rather just buy an assembled engine so we could just drop it in. I'm currently building a forged stroker for my mustang and thats currently taking the driveway spot so hopefully once we get an engine we could just drop it in one weekend. I've been talking to a few people about this and have been getting many different responses. For example I was talking to these Chevy guys and they said that engine from summit will work with no problem so then I called summit about to order and he said there would be major tuning issues. So I really don’t know who to believe. Would you please look at that link and let me know if that motor would work if we swapped manifolds, cross fire injection, and all the other accessories.
Thanks Again,
John

I was told to get a crate motor specific for fuel injection - does this make sense?
I dont understand what the difference in the crate motor would be carbureted or fuel injected??

interesting that the summit tech told you that..... if you slap your injection intake on that bad boy, I dont see any reason why it wouldnt work just fine.... the computer is not going to know the difference as long as all sensors are put back in.

I suggest you get the specs for the stock engine and try to match it up. If you want to beef it up a bit go to http://www.crossfire.homeip.net/ and read up. That site is dedicated to the Crossfire.
Lastly, what ever you do keep your block (rap it up and put it in the basement) and any other stock parts you don't use. Your car will be worth more down the road if you can supply the numbers matching parts.

Yes we are going to keep the block in the basement just to have. I'm going to Lincoln Tech next semester so maybe I'll rebuild the motor when I get a chance. Thanks again for the help guys.

I suggest you re-think the crossfire thing. While I agree that it should work, I'm sure the Summit guy is attemtping to mitigate CS calls about the engine running poorly when the problem could be the Crossfire. It was only in production for 2 years, parts are scarce knowledge on them even scarcer it seems. A poorly functioning fuel system would cetainly take the excitement out of your new engine. I would go with a carb. Keep the crossfire kit with the old motor in the basement. When you rebuild the original, then maybe consider re-installing it.

I dont think my mechanic did too much to find the problem. I think he just took the valve cover off and decided a new engine would be best. Maybe he's just lazy and wants the easiest fix?? He's my neighbor so I always just bring my cars there but maybe i'll get a second opinion.

I'd definately keep the original engine (in the basement or garage)

If your going to have to pick a Cam for the Crossfire FI then go with the GM Goodwrench 350 (260 HP). It's about $ 300 bucks cheaper, better warranty, and is identicle except for the cam.

Would I be able to order a cam from Comp Cams for this purpose. So I would just have to tell them the exact motor I'm putting it in and that its going to be fuel injected. I've search and havent found FI specific cams. Cams designed for fuel injection have more duration?
They dont make any crate motors that are Fuel injection specific? At least motors in this price range?
