Hi folks

Been a long time since I've been here.

I figure if I stay away from the circus on the general board, it should be OK....

Gotta a couple questions regarding Eddy heads (the closed chamber variety.)

Rated chamber size is 63 cc. How does this compare to stock '72 - 74 360 as far as chamber volume is concerned? is there a compression gain to be had by using the Eddy's?

Also - it says in the brochures and online that adjustable rockers or pushrods must be used. Why is this? It would seem to me that if a streetable hydraulic cam is used, this should not be neccessary. Or am I missing something?

Thanks in advance.
