Best Tips for Breaking in a New Camshaft
http://www.horsepowermonster.com -- The
first few minutes of operation will determine the long-term survival of
your flat-tappet camshaft. More agressive lobe designs, stronger
valvesprings and changes to the additives in modern motor oils makes a
"wiped" cam lobe much more likely than in the days of classic muscle cars.
These are a few very important tips for properly breaking in your high
performance flat tappet camshaft.

350 with Comp Cams Magnum 270H 112 LSA and 4/7 swap
This was my first time swaping a sbc cam. I left the 081 heads stock on my
350, but put new extreme push rods, 270h cam, and lifters. So, you can run
a .470 lift cam on stock heads. I spent many weeks looking for that answer
ans now I have the experience for my self. I also could not find a good
sound clip of this special grind cam online- so now there is one....enjoy!
Comp Cams Magnum hydraulic flat tappet grind #12-211-2, with two changes...
it has the 4/7 swap and LSA is 112 (instead of 110).
Built for 1.6 rockers, lift is .501"/.501
(If used with 1.5 rockers, lift would be .470)
