Welcome welcome. You might checkout the Summitt house brand cams. they're cheap & have a good rep for what they are. the specs would be listed there. I have one (not installed yet tho).

I agreee Summits brand cams work great and are reasonable.for close to stock use the smaller one.Ive run all their Mopar cams and a few Checvy ones.No problems.The big cam is a bit lumpy but not radical.smaller one is just a bit over stock and all OE parts work great and idles almost like stock with a bit more power.Rocky

Comp Factory Muscle cam for bigblocks, it's like a revamped 440HP camshaft, should slot in with no other substitutions. http://www.jegs.com/i/COMP-Cams/249/CL21-305-4/10002/-1 It's a little hotter than the Crane 680101 Factory Blueprint camshaft, the Crane has lift and duration very close to stock but the lobe profile has been smoothed out using computers. Lunati's Voodoo series the 10230700 is actually smaller than the factory HP cam, the 10230701 is nearly identical to the factory HP cam but with modern lobes that will get more airflow. Last but not least I'd suggest the Crower 267 HDP. It is a tiny bit bigger than the other three. It seems to be a very satisfactory camshaft, we have gotten good reviews on it. The 271 HDP and the Summit larger cam are too big, the summit smaller cam is too small. The four cams listed above should meet your needs and not make your car undriveable with stock drivetrain. Good Luck! R.

Your SCR might be fairly low so I would stay conservative

We just got the milder Howards .434 lift cam for a 383.It will be a while for results as it turned into a complete engine rebuild... RT

Hello
New to Moparts
Could anyone suggest a replacement cam for a 1974 Roadrunner 400 "P" code motor? I don't want to change the factory rockers or pushrod length if I don't have to? I see Sealed power CS-661 or kit KC661 with lifters, or Yearone MP31, Comp Cams 21-212-4. Cannot seem to find the exact specs of the original. Heck, what would Worman use? Also anyone use the Sealed power rockers or arms (vintage)
Thanks Welcome to Moparts! You have my reply on FBO. Someone here might know the valve spring specs that come with the AeroHead cylinder heads?

Are you looking to "replace" the original cam, or are you wanting to "upgrade" the original cam?
If your motor has the "2bbl" cam, it probably doesn't have the hp springs either, which would hinder the options unless changing them was part of the plan.
