My motor is almost ready to be assembled just waiting to get the rotating assembly balanced. I have 30 over dss sx pistons, scat I beams, stock crank, arp rods, mains, and head bolts, and flo tek heads with 185 intake runners. I have a comp xtreme energy cam and lifters from last years motor but I'm thinking of going bigger now that I have larger valve reliefs. I'm thinking of a tfs2 cam. But my springs are only good for .550 which is right where that cam is. I don't mind going with new springs but don't know which ones to get.
