I have a 440 0.30 over. The cam is a Comp # CL 21-228-4. The question is, can I use my stock stamped Mopar rockers and push rods? The Heads are Stage V (P5249112 2.14 int./ 1.81 exh) with dual spring (077).
You might get away with it, but why. You have that upgraded cam and heads, stamped rockers are gonna cost you lift. Some have reported their actual ratio to be closer to 1.4 to 1..besides that though geometry with bigger-than-stock cams is not good. Another issue with them, is with the spring pressure you (should) be running, how long before a pushrod pokes through one...no good. They may "work" but to negate some of the benefit of your cam/heads and roll the dice with reliability, in my opinion it's not worth it to cut a corner here on what sounds like a nice performance street engine...just some things to consider.
Can anyone inform me of what are some good choices of reliable rockers 1.5 to 1 and push rods that don't cost an arm and a leg. thanksYou might get away with it, but why.
