318 power?

Yep! In the world of N/A 318s, Even with a 4 inch bore for 333 cubic inches on a stock stroke, you’ll have to make 1.5hp/c.i for 500hp. I’m thinking methanol, W2 or W5, and 13+:1…
Lately, I really been wanting to put together a 333 incher from an ‘89 industrial hydraulic roller block with a steel crank, worked 974 iron heads and a 6-71.
