Well you bastards talked me into it, I have decided to invest in the bottom end of this motor. I am going to get a set of Wiseco Pro Tru pistons and moly rings #PTS531A3. Only $92.77 more than the stock 350np's @ $411. I am also going to buy the 440 Source rods at $250 and use Clevite 77 bearings. I've already got a Melling HV oil pump. What other suggestions do you have to spend my money on this bottom end? I will use mls head gaskets to reduce the CR a bit and probably use the Howards RV cam with all stock valve train parts.I am not going to put another dollar into the heads,intake ect.Please feel free to tell me what I am forgetting/missing...many thanks!
