ls2 and 243 or l92 for boost? Hey everyone, a couple questions:
Im looking at picking up a ls2 with the 243 heads and building it for some boost via a procharger D1. Im curious as to your thoughts on running the l92 heads vs the stock 243's. The l92 seem to flow much better, but with the larger combustion chambers im having a hard time finding a piston to run with stock rod length to get my around a 9.5:1 CR, best I can seem to find is around 9:11:1 (13.7cc dish). The car is 90% street driven, and does a bit of drag and time attack style events, so im worried about a drop in CR making it a dog on the street.
