Crane 274H06 Cam Chevy 305 Rough Choppy Idle
Farted around with tuning the 305. I gotta tighten down the headers but it don't sound too bad at idle. The Cam I am running is Summit K00172 which is the same as the old Crane 274H06. In Fact many people think Crane grinds Summits Camshafts.





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)
