Surprised no one has mentioned the 500 EFI cam yet. 230/236 .598/.610. This cam works good in my 454's

Yeah that 630 lift is a little scary with dogbones. My next attempt is with a ZZ cam I got free. Dry to tip Gils.

Believe someone mentioned it, but that Lunati 20010671 looks like a very nice cam.

Your existing hydraulic flat specs at 233/241 on 110.
And you are considering a hyd roller at 236/242 on 110?

Your Voodoo has fairly fast ramps for a flat hydraulic and 554/572 lift.
The Comp HR has fairly slow ramps for a HR and 521/540 lift.

Explain to me what sort of improvement you expect from the HR you have selected.
Listen to the crowd here - tight lobe separation does 2 things - makes the torque plot peakier - encourages reversion at idle.
Wider lobe separation does the reverse - flattens the torque plot - discourages reversion at idle.

I absolutely LOVE a tight lobe center in a stickshifted street/strip car. Throttle response is awesome, power comes on like gangbusters - DEFINITELY "less civilized" than a wide lobe center.
We are running a flat hydraulic on a 104 lobe separation in a Mopar 440 and it is a brutal dude compared to a similar B-body 440 that is running a 112 separation cam with similar compression, heads, induction, and duration.
But cars don't have water reversion problems.
