360/300hp cam suggestions

[maddart]

360 LA (Commando) motor-300hp version, what would be the best cam to use in this without head modification. Just cam/lifters/push rods and springs.

Bump. Rear gear ratio,tire size.Trans automatic/stick.If automatic,what kind of torque converter.Peak lift on the heads,should be .460 to .480 lift unported.

I'll throw one in for consideration & debate. This one's built to take advantage of the larger Mopar lifters. Not too radical and 110* lobes will keep it streetable.

Comp 20-227-4 Xtreme Energy/Hi-Lift

Isn't that a roller motor with 308 heads?

 

[Abodybomber]

Early Commandos used flat tappets.

 

[67Baccaruda]

Thanks, then the flat tappet cam makes sense.

Would have neen nice if it was a roller. Save the lifters, change the cam and springs and your off.

I agree.Was given a Magnum,the rollers are so nice.

From what i've researched the early 300hp had a .474" and the 360hp had a .484" cam. The 300hp also had the 1.88" intake valves. Being a hyd. flat tappet i think a regulation Lunati would probably make the most power. I would look to something in this range.....

I played with some other small block's over the years, but the Mopar sm.blk. is the most responsive to those kind of mods. And i love um' .....

Could be? I have a 360/300 Commando crate motor that has a 91 block with provisions for the roller cam.
