Re: New heads
Great advice from Eric...those 290's are a semi-open chamber design and with a little work, they will help make some decent power. As he mentioned, that is a lot of cam for a baby rat...I would consider something else if you can.
I don't understand the compression calculation?? if you are using 396/350hp pistons and the closed chamber heads, the factory ratio would have been 10.25 to 1. How do you get down to the 8's [img]<<GRAEMLIN_URL>>/dunno.gif[/img]
Check with Eric on a cam recommendation and make sure you have the compression ratio figured correctly.
