ET LS7 41" or AllPro LSW Just finished my 9:1 HKE 427 F1C build and want to start planning the next stage, an LS7 top end. With the as cast 243 heads we made 650whp/591wtq in 103* ambient temp @ 11.5# boost. Cammed as follows for a 1.8:1 rocker system. 238/254 /116+4 w/ lift in the .650 range. Trying to decide on ET LS7 or AP LSW's and will more than likely go with an OEM LS7 intake, 9.5:1 compression and around 16# boost.
