Im currently having to replace my transmission, transfercase and drive shafts due to a u-jiont failing at 75mph, and have always wanted a motor upgrade...so now seems better then ever. I wanted a diesel, but 7.3 is to heavy, cummins is way to $$$ and the 6.5 and 6.2 are "junk" according to 90% of the people i talk to I am a die hard Lt1 and Ls1 fan, i know the lt1 better then my wife, but having just moved to NM, i dont know anyone and have not been able to locate one via club members. And aparantly the junkyards here think the LT1 is made from gold, wanting about 3 times the going rate.... So anyway, seems i can pick up a low mile 5.3l LS series complete from yard here out of 2000-2004 chevy siverados for about 1500 bux.... what do yall think about them? 295hp/335tq and decent MPG think the swap will be hard? Will the belhousing match up from a 700r4? I think the worst part might be fabbing up new motor mounts, hooking up the cable to the tranny, and putting in the right fuel pump Opinions? other options?
