Post Chevy 302

Was reading the posts on the crate 302, thiught I would add my 2 cents. I am the owner of a 302. Mine came with my 69 Nova, go figure. Mine is a March 68 block with a large journal original steel crank. The casting is 3279. Unfortunately or fortunately the 302 did not have a specific block made only gor the 302 there were several blocks used to create the 302.
The mis conception is that all 302's were small jrnl motors, this isnt tru. Even the local speed shop insisted mine was a small journal, until I proved it. The heads on my motor even have the correct casting number used on 68/69 302, but mine oare replacement cast iron units from another local speed shop, even has there name stamped in the ends. 302 were created specifically for the Trans Am circuit. The are extremely high reving motors, thats why one would desire 2 short stroke motor, less heat..... etc..

There are several advantages to min motor. If I explode the crank, 383 stroker kit would do just fine. Maybe some relief cuts in the cylinders to clear the rods, we're set.

Thanks for reading, Have a nice day !!!

true enough, i have a may 5,68 327 and it shares the same cast #s with the 302 and the 350 of that year. it also has a large journal crank, the only way i could find out what it was to take the top end off and measure the stroke. <img src="graemlins/mwink.gif" border="0" alt="[mwink]" />

You gotta check the stamped or suffix code on the right side front of the block to know for sure.

i've had a few problems with the stamped codes on the front of the blocks, they'er some machine shops that stamp their own #s on them.i wish they would leave well enough alone. so i hang on to all the books that my dad and brother gave me.they don't have all the #s and i usually cross ref everything just to make sure but sometimes even that is not enough.

I need one of those large journal 302 cranks, they are pretty rare.

And for a mere $1500 they will gladly ship one to your door They are just to damned expensive for a street ride, unless you are just dead set on a 302.
