    I have two SBC'c in pieces at home. One is a 283 .060 over with aluminum pistons, and the other is a 327. I was going to rebuild the 327 first as a head long attempt at my first rebuild and then do the 283 next. Then a guy told me to put the 327 crank in the 283. He said this is what he used to do in his drag car. What is the cubic inch then, and is there any clearence problems? I'm thinking I should just stock rebuild the 327 to learn then rebuild the 283 for my Jimmy. Any suggestion? Thank's

    You need to scrap both of those and build a solid 350. Just my 2 pennies

    It would be around 308 to 310.

    Yeah, get a 350, but maybe rebuilding those motor's is good practice... If you rebuild the 327, maybe you could trade someone for a 350, I know there are a couple dozen guys up here that would give you cash for it for thier "factory restored" early camaro's... I know the 327 is a slightly in demand motor to restoration guys. If I had one, I wouldn't use it for my K5, but I'd rebuild it then sell it.

    I want to rebuild them for practice. They are out of mid-late 60's cars or trucks too. I plan on buying, or building a 383 stroker for my Jimmy, so if I can sell these motors that would be good. My Jimmy has a 350 in it and I plan on keeping that until the 383 comes, but the 327 I might use for a spare just in case the 350 goes down. Anyone know how hard it is to build a 383? what special things need to be done to the block?

    Putting the 327 crank in the 283 gives you a 302. Thats what they did in the 67-69 Z28 Camaros. Those motors were screamers. Most of the Z28s were 12 second cars right out of the factory. You could also rev them up to 8000 rpm.

    I'm interested in getting a muscle car later in life. I think that the 302 with the aluminum pistons and a light valve train might just be the ticket for that car. Did they rev 8000 from the factory or is that a race motor? How did they get them to rev that high? thanks

    They reved 8000 rpm from the factory. If you want one to rev that high get the motor balanced and blueprinted, and put a good set of valve springs in what ever heads you decide to use.

    The good thing about destroking the engine is that you get a faster reving engine. Problem is that you give up other good aspects. The 327 is a real good engine but does have draw-backs when it's put in a truck where you're looking for massive bottom end torque.

    How should I build it and what type of power number should I look for? What compression, cam, heads, etc should I use?
