Questions for a sbc rebuild...

I have a few questions concerning rebuilding a chevy 350...
I haven't bought the block yet, still shopping around, but my question is can a 1970's or 80's 350 block fit in an old chevolet car,like a nova for instance. I
don't want to rebuild the motor and not be able to fit it in an older model chevy car. I would prefer a straight shift transmission,,,,,should i go through the trouble of buying the block and the transmission at the same time,, or just try to find a transmission at a junkard or something.

One last question,, i've always heard the phrase 2 or 4 bolt main,, what exactly does this mean?

Thanx for any help i can get

Chevy II's, as they were called before they were Novas, were available with a V8 somewhere around 1963 as a dealer installed option I think, although factory installed V8's had to wait until around 1966 (283's, 327's).

So yes, a 350 will fit into any Chevy II from 1962-on.

You'll probably have an easier time of it if you locate an engine/transmission combination.

The crankshaft is fitted into the main saddles of the cylinder block with insert bearings and is held in the saddles with main bearing caps and bolts. The small block Chevy is a 5-main bearing design with 2 bolts per cap to secure the crank. These are known as 2-bolt blocks. Some high-performance versions of the block used caps with 4 bolts to hold the center #2, #3 and #4 bearing caps into the block. These are known as 4-bolt blocks. 4-bolt blocks are only necessary where extreme rpm's will be used or where the engine will be supercharged. A 2-bolt block will work fine for any street motor.

Some problems you might have. The oil pan is a little bit different. Also not all later model blocks have a place to bolt a clutch cross over shaft. It has been 30 years and I can't remember all the details. That used to be a real popular swap.
