I have that Howards solid 260/264 cam in my 10 to 1( maybe) stock stroke 360. Mine is on a 106, its mighty choppy, love it. They have a 108 version as well. Both big and smallblock.
On an 11 to 1 470, its certainly nothing radical.
Mines on 108, I'm going to try a shorter cometic gasket .030 & get to 11.4 cr. Don't want a dog & Yeah, that's what I was aiming for (not radical) but noticeable & pleasing to my ears, what stall do you run?
