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?>>>??

 

too much injector... go 30# or 36#

 

if you got them give them a try.

 

what the worst that can happen???

 

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.

 

so 42 on a 357 with heads and cam and a 150shot will be okay????

 

ttt

 

It will be fine. If you are using the stock computer the start pulse will be a little rich but you should have no issues other than that.
