Engine was never reved past 6500rpm, there was a 7000rpm chip in the msd but
it was never hit. only lasted 3 laps on the track! and one of those was
towed in because the wire from the coil fell off! and the other 2 were
learning the car. we had to put a new valve keeper in, new valve
(obviously), ground the valve seats down, cleaned up the piston. what one of
those pics doesnt show is on the piston, there is a 1/2" dent in the top of
the piston. cylinder walls are a little gashed. freshen up the motor this
winter. compression is only 160 in that cylinder and 165 in two others and
one cyliner is 185. kind of low for 13:1 pistons, rocker arm has a crack in
it... seems to have held up for this whole weekend. I put flat valves in, i
know thats not as good of flow but it allows for more clearance. I dont know
the spring pressure im running tho... how do i find out?
