Comp cam 20-600-4

It MAY be ground on a reduced base circle. If it is, you may need longer pushrods. You're just gonna have to see.
so, i did a little digging and nowhere in comp's literature does it mention or recommend pushrods. nor does summit or jegs in their suggestions or required parts-- which no surprise on that one. but for comp not to have word one about it was interesting.

naturally i fell down a wormhole only to read accounts of cams being ground on smaller base circles, but the eye opening part was telling of cams above 440 being subject to this. i mean, i expected much much larger would be as would pretty much any regrind.

anyway, from what limited research and perusal of items i was able to ascertain that it seems to be the "Mutha" and "Big Mutha" variants are likely to need longer pushrods. although this was reported on chevy motors, so it may not hold true for our vastly superior mopars.

so file it to: trust but verify.

also: that RRR for makin' me learn something today, ya jerkus.
