ive got a 351W with Z304 heads and a .518 hydralic cam with a good intake, flat tops and running a 150 shot of gas wondering if 42lbs will be okay already got a set wondering if i should use?>>>??
it runs fat wash down the ring gets lots of gas in the oil and takes out the bearings. I have been running 42s on a 306 for years yes it was S/C but its not under boost at a idle and have never had problems with it.
