408 Cam on the way

Thumper hater here
rusty where do you get 5 degrees? which would be great
agree on the advance issue
get 13 degrees at .050 and
20 degrees more advertised exhaust duration for a Magnum head
WTF
It's real easy to roll your own thumper style cam'
or the Hughes version- well do a quick compare I'll post one tomorrow
comps version is like their dual power scam- a marketing gimik
I'd take a purple power if limited lift (stockish heads) or the xe-hl grinds
otherwise comp is a con
anybody else think a long rod motor needs different cam timing than a short rod motor?
