The super long exhaust makes no sense to me if headers or late/ aluminum heads and long even for stock heads
ask yourself are you limited to half inch lift
It would seem that the 340 Whiplash would Thump the Thumper and Rattler
and the top four cams would be a better choice or get those lobes ground on whatever LCA floats your boat
The bottom 4 are a little bigger than the thumper intake but may have a better intake/ exhaust split some exhaust lobes are not shown U pick

Cool info. Thanks. Sorry if I didn't clarify, I've already chosen, it's in the works. Just making conversation about it, and interested to get some idea what to expect from those who know more than me.
