TREX is bigger than MS4...so it Polluter, G5X4, Vindicator, and several other cams that "fit" a stock cubes LS1...however bigger is not better in a 346ci. Look at my old 98 car in my sig...I always wished I had gone a little smaller cam wise. The TREX V2 I had was 243/249 .613/.619 110+2 and didnt do much below 4500 rpms...pulled like a freight train above that though...which in my opinion is wat too big for a daily driven street car. Something around the size of a g5x2 is gonna be about as big as needed for the street.

compared to what? I tested that cam back to back to most of the others you listed, and thats is not what I found. In fact it made more




OP- you can run a cam with .650 lift on SBE LS1s (FTi hellion, ect.) PtV get tightest about 10-15* TDC. Its not about the max lift, the piston has moved out of the way by that time.
