720/600

Would there be an advantage with a 110 lobe separation?

i'd put a bigger head on it with a cam that big ,, but thats me , or i'd tone the cam down

[af2]

The cam is not that big. Sounds like someone will spin the thing where it works and not the usual 7000.

[RichardThiessen]

I tried that cam with my 427 sbc, 14:1, ported super victor, ported dart 230's, 1090 demon, no vac pump... made about 640/550

[clevo]

660HP
You need more head to make more HP

[SupStk]

My guess is 725 and change if everything is right. Seems to me you have enough cam...

[BrazilianZ28Camaro]

Carb seems a bit small

The guesstimate will be 680@ 7400 /610tq 5600

[RichardThiessen]

I think I need to find a happy dyno... maybe then I can get to 700 hp

[xanadu]

If that does'nt make 650 / 600 on Alky, i'll gladly eat my hat

[mygtr]

Will post results once we hit the dyno in about 12 weeks.

Is that .724' intake lift with the 1.65 rockers or would it be 724 with 1.5s and therefore alot more with the 1.65s?

[levisnteeshirt]

it could use a bigger head to get the most out of it ,,, but ,, see what it does ,, trick flow has a 18 degree head prolly for close what you'll pay for those AFR's ,, i know what i'd get

[mygtr]

724 lift is with the 1.6 ratio, my bad (not 1.65) Have seen pump gas combos make 650 easily with these heads. Would love to go 18 degree but that means another $2000 in custom pipes. I will be over the moon if we can make 700 as that will see my 2650lbs car into the 8s. We will be trying a ported plenum super vic (2970) as well as an out of the box version.
