318 build suggestions?

Hello Neil, good to hear from you.

We have bored several 318 teeners to 4inches without any issues.
That's a 90-thou overbore for a 402cube with a 4 inch crank.

My new idea is 110-thou overbore with turned down 340 pistons.
If it stays together I will take it out to 130-thou for some stock 340 slugs.

The Hinkles did this kind of overboring for their 426 Poly build.
They said finding a Poly 318 block was very hard so they used a Teener block.

It stayed together and made over 600 horsepower...:thumbsup::thumbsup::thumbsup:
