i have an idea

i was at work today and got an idea, what would happen if you could get a 350 crank into a 305 block, basically stroke the 305?

is this possible and/or what other parts would be needed

just an idea

thanks

russ

The stroke is the same for both engines.

so basically there would be no advantage to putting the 350 crank in the 305?

thanks man

I have never done this myself. I have put small journal 327 cranks in 283 blocks, but I'm not sure if you will have enough clearance in a 283 for a 3.48 inch stroke. You will definitely have to get out the grinder to make it clear.

283 and 350 rods are the same lenth. The main bearing journals in a 283 are smaller than the 350/305 ones

hmmm...

a 283 block with a small journal 327 3.25" crank would make a 306

and a 327 small journal block with a 283 3" crank would make the famous 302.

you could make two interesting engines from to normal engines.

has anybody ever tried a 306? it would probly be a little more torquey than a 283. but it would probly be a waist of a good 327 unless u just had a 327 or 307 crank lying around.

never mind, that would just make a 307, i forgot to round up.

a 283 with a 327 crank is a 307 which is exactly how chev made the 307 with the exeption of the fact that gm used a large journal crank

indeed, its too bad they chevy made different journal sizes. it would be cool to take a 4.125" bore with a 3" stroke, now that would be cool, a 321.
