l92/l76 or 2.5 5.3/fast on 408?
I currently have some tsp prc 5.3 2.5r heads flowing 308 that are 62cc, 2.04/1.575 with a FAST 90/90 ported for them. I have heard some good things about the l92/l78 setup and it sounds like i could almost recoupe all my money on them if not more by just swapping over. Is this a worthwhile endeavor? what kind of power change are we looking at?
