Reply to "COBRA JET: Unleashing The Performance Capabilities Of 351 Cleveland Engines With Open Chamber 4V Heads (Q Code)"

i don't think anyone's talking about controlling DCR during the overlap period (intake valve opening) but rather when the intake valve closes ... when the actual physical act of compressing whatever is in the cylinder begins and the exhaust valve has been closed for quite some time

but as far as overlap barking at idle, Yes the Crane F238 barks sharply when the throttle is snapped

by no means a nice driving cam, the F238 trades idle & low speed characteristics for high speed scavenging which i believe it does pretty darn good! FWIW the F238 has less lift more overlap than the F246
