I posted a dyno for my 400 eng. small block,and they made me go out and buy another cam a roller actually,so if I could get anyone to give me a reading on the desk top dyno I would surely appreciate it.Here are the specs:

Exhaust @cam 352 @valve 528
1.5 Rocker Arm ratio

Intake opens 31.0 btdc Intake closes 73.0 abdc Adv. duration 284.0
Exhaust 79.0 bbdc Exhaust closes 33.0 atdc Adv. Duration 284.0

I am using fully roller retro fit lifters

the springs are 1.440"
1.875" installed height 130 pounds seat pressure
I am using full roller aluminum racing rocker arms with a 1.5 ratio
The intake is a victor junior open plenum rpm range 3500-8000 rpm
The carb will be a 700 750 800 cfm double pumper holley or speed demon
not sure may-be this will tell what size carb to run.
well here is the specs.I hope I didn't forget anything
If someone could give me a ball-park figure on desk-top dyno
It what let me know is this the right cam or not
thanks hotrodder.com is the best

well depending on what you end up with for exhaust and the parts you suggested, you should be bumping out high 400's. 460-490 horse or so. Are those heads CNC?

I don't think they are,but I was thinking about port macthing the intake,and smoothing up the combustion chamber.
