Hey, just became a member. Does the new aluminum L92 block bolt in place of a LM7 or LQ4? Also, will the stock L92 intake make any hp over 5500 rpm? I'm selling my 10sec 80 Trans Am race car and just purchased a 04 Sierra Z71 ecsb. Want to build something I can drive everyday instead of a barely street legal race car that sits in the garage most of the time . Thanks in advance. Been thinkin a GMPP 416 ci L92 stroker 11.1:1 cr with L92 heads and about a 220 duration cam(don't have one picked out yet?) with a 2800 stall and 4.10 gears.
