there's NO OEM small journal 350 cranks.
i'd think aftermarket only..

Put a 283 crank in it and have fun!

Jeff, Great Idea, I did a 302 for a customer of mine last year with a .650 lift roller, some Dart Heads, and a Tuned Port Injection set-up. It runs on E85 and sounds like an Indy Car. It is in a 67 Camaro Street Car with a flat hood and 4-speed. Fun car.

If I remember right will the big joural crank swing in a small journal block with out a lot of grinding, some 283 s won,t take a 327 crank.

I don't know if there is a readily available small journal aftermarket crank with that stroke. It is not difficult to have a 350 crankshaft machined to fit. If you do that, you could then use small journal rods to make the historically infamous "9/16 stroker" and make 368 cubic inches. Tom Meyer is correct, you should check clearance in the crank case before you start assembling.

I believe your quote is incorrect...

The first 295HP / 350" in '67 were o.e.m. assembled Small Journal Cranks...
It wasn't until jan / feb '68 production that GM went to the Large Journal 350"...
Dwight, is my memory correct?

(I'm done with the 283" stuff / just sold the 721 blocks, cranks, etc that I had been sitting on forever)

Thanks again! Larry

If you could find one it would be extremely rare. I have never seen a small journal 350 crank. You would be much better off using a 4 bolt main block. Unless you have one of the very early 327 blocks they are not reliable. I ran them for several years in my car and had lots of split cylinders. Switched to large journal cranks and 4 bolt blocks no more problems. Better yet get a bowtie block.

Good advice!
