Is this cam too much for my combo?

nice cam for 11.8 compression.

as moper was saying, stick the head on an empty block to determine wether it necessary to bore notch.
and of corse talk to brian and find out wether he's doing an unshrouding cut on the chamber, best not to maybe, stock j's can be a lil bigger sometimes than the 318 bore.fwiw

should run reeeeeeeeel goooood.
