What is the best comp cam for E heads big valve, and what is for Edelbrock heads?
engine:
461cid, 10.5 compression, torker intake, Holly 850dp, MSD sys., headers.

Im looking for great combo for Hi-performance street race and drive with no problem.

 

dude that is such a vague question...the best cam for me may be too small for you or vice versa. Do you really have 10.5 compression? Do you have power brakes or anything that needs vacuum?

A little more background for the car and your experience would help in determining what kind of cam to recommend for you.

 

there is power brake and vacuum

 

Olds 461, big valve “E” heads ported and polished, Mondello pistons, high volume oil pump, windage tray, ARP bolts, 10.5:1 compression, MSD system, FT headers, 4:11 rear end.

 

How about lunati voodoo 276/284H or comp cam xe274H?

 

Why are you limiting yourself to those cams?

 

Do you prefer another cam? I want to get the best cam that work with my engine.

 

What heads? Iron? Edelbrock? Ported? Unported?
That makes a difference.

 

previous owner said it's big valve “E” Iron heads ported and polished

 

Then I'd do an Erson with their .355 lift lobes, probably a 236/244 on a 112. Lift would be .568 on both. With ported heads and/or Edelbrock heads the added lift is worth something. Otherwise it's a waste.

I sold a similar cam to a guy with a 455 Buick, ported iron heads and a 175 shot of NO2. Made 580 at the rear wheels.

 

Gears tire size finnal gear ratio matter! Car weight,a/c,heads flow rate. Are things to consider. I have had my best luck with the comp cams there tech help line is good dont hesitate to call them. You dont want to be pulling your cam out or your engine after installed! Make sure all your engine coponents are part of your engine build! Good luck.
