Last summer got my 348 built from the bottom end up. Billet connecting rods, Diamond pistons, rings, and a whole lot more to list. The only thing my motors missing is a nice set of heads. I have a custom speedinc grind s15 cam 231 237 .589 .595 112 with patriot gold dual spring kit and comp chrome moly pushrods. To make a long story short I'm thinking of going with a set of trick flows with a fast 92/92 set-up and probably some aftermarket rockers and valves. Any suggestions of a different setup would be appreciated. It's mostly a street car a only will see the track a couple times a year. Also have a vig. 3600 stall.
