I have 2 quick questions on my '74 Stingray.... I have the stock 350 engine and want to put a new engine in... don't need it for racing, just want reliable and something that will sound cool can anyone recommend a good crate motor that won't break the bank? Also was looking to get different rims and need to know how you determine the offset of a rim. Thank you for your help!!
I bought a GM Performance Parts 330hp/350 from Summit a couple of years ago and have been very happy with it. It was right around $3k with a new intake, flywheel and distributor gear. I was able to reuse the other stuff off of the original engine.
To determine the backspace of a wheel, lay the wheel face down. Then lay a straightedge across the rear of wheel and measure down from the straightedge to the machined area of the wheel that contacts the brake rotor (the lug nut hole area). That will be your backspacing. I think if you measure your stock factory wheels you will find they are 4" backspaced. That is for a factory 8" wide wheel. I have 9" wide wheels on my 80 Vette and they have a 5" backspace, in other words the extra inch of the wider wheel is positioned in toward the center of the car. This wheel size fits my car, may fit yours also. This backspace puts the outside of the rim and tire in the original position in regards to the fenderwell. Be careful when you buy wheels, some aftermarket wheels do not clear the Corvette brake caliper. If you find some wheels that you want to buy, you might be smart in posting on the forum what they are and let the forum members advise from past experience. Just post the name of wheel and size of wheel and the backspace. Good luck.

What is wrong with your present engine? Not enough power? Not running right? Breaks often?
If yours is reliable, you can get a bit more power or other changes a lot cheaper than a crate engine. If you are having rough running, it could be anything from needing the carburetor rebuilt to having a tune up.
Or the engine could really be worn out. It is important to know before anyone can advice you on the best course.
It seems a lot of people just drop in a crate engine, but for the price, you can often do a lot more and has as good or better on your own.

There are plenty of things you can do if you want a bit more power.

Look into a ZZ4, very nice motor with gob's of power right out of the box. In regards the wheel off set question, what are you looking at to replace what is on the car now? To completly understand wheel offset / backspace...just google "rim off set" and you will find numerous descriptions...copy the one that you understand best.
Run some seafoam through it and change the timing chain, should be good to go.
Just from the two items you mentioned, I would comment that this engine is very tired and in need of rebuild or replacement assuming you are looking for decent performance and reliability. If the current engine is the original block with the original VIN stamp you should consider finding someone local with a good rep to do a rebuild on it. If it is not the original block, or you dont care about keeping the numbers on a 74, go straight to a GMPP crate motor and don't look back! If it is an original L-82 I would get it rebuilt...maybe with some porting on the heads and good intake upgrade!
If you go the GMPP route, i agree with Gregg...ZZ4 is great $$:whiplash ratio!
If your serious about a new motor, I would recommend a new GM engine from there performance parts book....any dealer through out the US could warranty the engine unlike some others from whoever or wherever,,,
