I use this cam with 1.6 rockers in a .030 over 360 with slugs at zero deck height and a .028 Cometic head gasket and trick flow heads. TTI exhaust stem to stern. A 904 & 3.55’s with 26 X 10 tires.

Rumble have you measured cranking cylinder pressure with this cam?
I use the same cam in my 340 and have recorded low cylinder pressures.
Always wondered if it was the cam or other?
