I had Oregon regrind my cam and lifters. $109 for the cam a $6.00 each for 12 lifters. I got a 1410 grind which is 218/226 @ .050, 262/270 adv., .441/.449 lift, 112 LSA.
That is supposed to be a cam well suited for 9.5 compression, 3,000# car, manual transmission. My machine shop cleaned up the bowls and did what they call a "performance" port and chamber job. New valves and bronze guides. 340 springs and retainers from Comp. 100# on the seat, 275# @ .455 lift.
I'm part of the cast crank rod group purchase. I'm using long rods and 2.2 Chrysler pistons.
