Stock Mopar Rocker Assembly... Sheeesh!

As I stated earlier, stamped steel stock rockers are durable enough, they have proven that. Just not a performance part. Yes I am the type that checks everything...twice. I have to get my flow chart out for this one.....my heads flow 226 cfm @.475, and 240 cfm @ .500, and 254 cfm @ .525 and holds that thru .550 lift and then stalls. My cam is the comp XE 275HL (.525 lift) It measures .544 @ the valve with the 1.6 cranes I am using. If I used the stamped rockers this cam would give .476 @ the valve. With the small block Mopars we are already losing .010 lobe lift because the lifter is not in plane with the pushrod. The calculator says .350 lobe lift with this cam..but it only measures .340 . I would lose 28 cfm of flow. Using the Super Flow formula, thats aprox. 57.68 horsepower. Would I change rockers for "5-10" horsepower..no. Would I change for 50 some horsepower...well..I did. Like I said, for a street beater, sure the stamps are good . I used them for years myself. And for a low buck hot rod use them. I was just informing others that there are better rockers out there that don't break the bank. And deliver more performance for the investment. m. At 169.00...they arn't much more than a set of new heavy duty stamps. As always, JMHO. Use whatever you choose...I do.

Pastortom1, sorry for getting off your subject...just trying to put some informative related tech out there.
