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!

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)

This is my 1977 Nova RS.. This was my first car at the age of 15. After

Rocket Racing build me a 358ci Chevy to put infront of the 4speed. I have
added a new rearend with cal tracs, 6inch hood, 3inch Exhaust with electric cut outs, and new front
seats. Future plans are paint (once i figure out how), perfect fit TKO
5speed and maybe a mini tub/335 rear rubber for more of a pro-touring
