If you are talking about the 95-97 LT1 Camaro-Corvette cam #12551705 it is actually milder than what comes in the ZZ4.

LT1 #12551705 duration I:201, E:208 @.050 lift, Max lift I:.447", E:.459"

ZZ4 #10185071 duration I:208, E:221 @.050 lift, Max lift I:.474", E:.510"

Earlier Corvette LT1's (70-71) used cam #3972178 which was a mechanical flat tappet cam

A ZZ4 shortblock is a good building point from which to start, that has a bunch of really good heavy duty parts, but must be combined with the proper 58CC head to realize it's potential.

For Deuce: Your ZZ430, does it have the "hot cam" #24502586?
