There are plenty of cross members and motor/trans mounts to bolt it in the car but the shifter is in the wrong place. It's 7 inches back and centered so you have to move your console. You have to deal with switch from mechanical to hydraulic clutch. The coolant flows in the opposite direction in LS1 so you need different radiator and fan. There are issues with fitting ac compressor without notching the frame. Issues with getting the gauges to work. The gearing on the T56 requires your rear end to be in the upper 3's so that you're not turning 700 rpm at 70mph. Many LS1 require fuel rail mods to convert to return style plumbing. You have to set up electric fuel pump and plumbing.
My goal is to have efi benefits and an overdrive for cruising speeds. All of these LS1 issues are surmountable but I think I can get these in an easier way with an efi kit and tremec TKO600 trans on a poncho 400. And then I have the benefit of having a close to stock appearance under the hood and what I believe would be better value to the car. Or hell maybe I'm just lazy.
