is the steepness of the intake lobe the same as the steepness of the exhaust lobe on an lt4 hot cam? in other words, does the intake rod get to full lift quicker than the exhaust?

 

.050" valve timing:
intake open .3 deg BTDC close 38.8 deg ATDC
exhaust open 49.1 deg BTDC close .2 deg ATDC

No. Yeah.

 

rezinn, good call, that just made me think of the answer. since lift is the same on intake and exhaust but duration is less on intake, the intake valve has less time to open so it must open quicker. which means it should have a steeper ramp.
