Ok, so to start I've got a 1988 C1500 RCSSB. It is a base model 5.0/automatic truck. BORING! So, where I'm going with it is a bit more on the entertaining side. Starting with the interior, I am replacing the 1988 - no power options - interior with a full power 1998 (done the right way). After that I will be tackling the underhood area. The upgrades there will include a LQ4/6.0L backed by a 4L80E transmission. The LQ4 will be fitted with turbo (~S475-S480ish) targeting a relatively conservative 650whp. The plan is to park it all on a 5/7 static drop and a custom rear coil over suspension that I can take to the track. Progress will be fairly slow right now as I'm trying to wrap up my LTx 396/4L80E build that almost cracked the 500whp mark N/A (496whp/437tq), but will progress, none-the-less.
