WerbyFord, thank you very much.

That's a lot of info you posted and must have been a lot of work.

They're iron Genesis blocks. 4.31 is a common bore size and I think the next is 4.375. Didn't want to take it that big on the first build though. I should have had both blocks taken to that bore size.

For the 482, I think I'll start with the first cam like you suggested and see how it goes. Won't have to rev too high with that one and doesn't lose much compared to the others according to your calculations. It's a pretty small cam and with 110* LSA, should behave quite nicely on the street.

Thanks again!
