I picked up a pretty clean 1990 240 wagon with a 5 speed a few weeks and and decided that I wanted to go fast. I ended up picking up a lm7 5.3 and a 4l60e from a 2004 Silverado. The engine combo was from someone who had already prepped the engine for a different swap, it had a f-body accessory drive and oil pan along with a PSI harness. The goal was to just get everything together and get it running as fast as possible, I'm moving and losing my garage. Eventually ill do the 8.8 swap and upgrade the brakes/suspension, but for now its pretty much stock.
-The engine mounts I built using a Barnes 4x4 cross member kit, and notched the cross member so the f-body oil pan would have room, and the engine and trans can go in in one piece.
-The headers are the summit brand ls swap, and the STS machining steering shaft for clearance.
-Fuel system is a walbro 255 in tank with an6 lines to a corvette regulator.
-Single piece driveshaft made locally.
-Purchased a stock volvo auto shifter and made linkage to shift the 4l60e.
-Kept the stock brass radiator, it was in great shape, but wired up a 16" pusher fan.
I'm sure there's more but that's all I can think of right now. Took about a week, wasn't terribly difficult. I'm still finishing up the gauge wiring, and waiting for a sts cross member to come in (I have a temp one I welded up)
