Depending on how tight the piston to valve is on this motor, the cam being off 14* could cause it to kiss some valves.

We broke a pushrod on the 738 once in the burnout and it killed the motor. Went back to pits, fixed the pushrod, fired the motor, it ran like ass and couldn't figure out why. As Fast described, we did a compression check and they were everywhere. Pulled the heads and all the valves were bent slightly......but why? When it broke the pushrod, it caught under a rocker, stopped the cam and jumped the belt drive a tooth. Took the gear off, lined cam back up, touched up the valves and were racing in a few hours. Did all this at the track
