Hi I have block ?. NHRA 307 olds stocker non roller engine. Are you using the factory 307 open main web block in stock or is it legal to sleeve a 330 or 350 solid main blocks?
Thanks
Bernhard

Yes, you can sleeve a 330/350 block but I've never heard of the 307 blocks being a problem in a Stocker.

I've seen a 307 pull the center mains out of the block. It may not be common but it can happen. It isn't a pretty picture.

Some 25 years ago, there were about 6 thousand 307 Olds stockers running around. Those motors were beat to death and proved to be quite durable.

Unless you’re using nitrous, nitro, or some other exotic ingredient, I would not be too concerned with the “windowed mains” scare on Olds motors.

You should contact Don Forester. He uses Dave Smith engines and they have some of the fastest Olds Stocker stuff out there.
