Thats the plan. I picked up an RV 454 with 42K miles on it for $150 hoping it was a 4-bolt block, it's not. No big deal because an ARP stud kit and balance should keep it alive in the 7K rpm limit. Would like to break into the low 12's with this motor running a solid lifter cam with forged domes. Just got the motor tore down today, inside was clean, all the journals looked good. What I found surprising was the plastic timing gear, normal slack in the single roller chain, but both front oil galley plugs appear to had been drilled with a 3/64" bit? The oil filter housing had an extension on it with two cut off nipples still attached? It appeared to have been remote oil cooler lines? I thought drilling the plugs or just the right galley plug was a builders trick although this motor appeared to be stock? Maybe something only RV motors got? I had an L34 396 out of a 69 SS El Camino, it had 0.060" over 25cc forged domes, (408ci) 101cc closed chamber heads, and a Comp Cam 268H cam with roller rockers. I was turning 14 flat in the 1/4 with a built 350 turbo and a 4:56 12-bolt Posi...Until it threw a rod right out the side of the block @ 6K rpm. I bought that motor already built, hoping to go faster and live longer with this 427...Thoughts?
