This will be for a n/a 408 on 91oct that will be going in my 86 W150. It wont see more than 500hp and rev no higher than 6500rpm. I was gona go with forged IC983 27cc 9.1:1 or hyper KB416 25cc 9.3:1. It sounds like hypers can handle more than the factory thin-wall block, so I'll order me a set of hypers.
What rings would guys suggest for the best longevity???
Thanks for all the input :thumrigh:
