For interest, similar from about 13 years ago by Ken Crocie. A 455 based combo, about 285-288 cfm 'cleaned up' alum heads, 10.2 compression, Performer RPM intake, a 'big' Comp 320H hydraulic flat tappet cam with 268 degrees at .050", 110 LS and 0.606" net lift at the valves.
Produced the exact same peak power at 5800 rpm on the dyno. Like Cliff eluded to here, if you examine the actual lift curve at the valves, this modern quick-lift hydraulic flat tappet cam, in conjunction with high-ratio rockers and Rhodes Vari-Duration lifters approximated the valve-lift curve of a traditional solid roller to about .600" valve lift. But it's going to take additional intake duration. .

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
