My 2 cents advice want 100 % VE at around 4000 rpm.
Peak Hp 6200-6500 stay in Grumpy safe zone.
We actually exceed it easy, been a while but I recall safe zone piston speeds 496 reached at 5800 rpms. Got good parts, no worry to me.

What's the difference in new cam?
Great data thanks again for all your guys
Help.

OK. In a few minutes.

Guys at comp are ding dongs by the way.
ONLY LOOK AT THE HI-TECH DRAG RACE SERIES RACE CAMS.....DANGER ZONE...NEED TITANIUM VALVES, GRUMPY HAS A HEART ATTACK.

CRANE, CROWER, & MY FAVORITE ISKY STILL BETTER !

New Cam specs IVO, IVC, EVO, EVC are advertised specs not checked @.050 lift.
See how the results are, may be skewed. Not quite apples to apples comparison.

OK Gained 100 HP and a bit more.
I am not sure how accurate results are because I know for a fact its most accurate using .050 or .020 listed valve events in degrees checked with a cam degree wheel & dial indicator.

They are seat to seat timing specs as Howards listed for us.
Seems 50 Hp high or more.
Post soon.

VE looks a lot better, you said 100 right?
Yes it does appear better but theses are advertised seat to seat specs, they inflate engine simulator power results.

Crane & Crower & ISKY Cams are the only that play by the rules set in stone by Smokey Yunick himself. Check @ .050 or ..020: valve lifts.

Done to inflate numbers & sell camshafts.

The 112+4 Howards has a better torque curve for drag racing & still streetable.
I favor it.
Torque hit up high....Need 5,000 rpms stall to make most use.
4,000 RPM stall required now at least....weigh options yet.
