Talking Re: Bought my old K5 back, now receiving a 5.3 swap...

Update:

Had a 4L80e build from the bottom up, all new parts/electronics, Trans-Go HD2 shift kit, etc. Builder sats it good to at least 1000HP and will tow anything I want, even in overdrive. Converter is a GM reman, 2000 stall.

I also bought a '02-'04 LS6 cam/springs/pushrods and swapped them prior to installing in the K5.

I went ahead and bought some eBay F-Body stainless steel long tube headers. Both sides need mods to work correctly, but nothing major.

Although extreme overkill for this engine, I bought some 8.1 litre marine injectors (42 lbs). Incase I ever turbo this motor, at least I will be set with good enough injectors for my power goals.

I had to find another NP208c with a 32 spline input shaft to mate up to the 4L80e since the first year 4L80e was 1991 and the last year for the NP208c was 1987 (at least with GM). I had to knock out an inch from the rear driveshaft, but the front will work.

Still have a bunch of little things to do, but it is progressing nicely.

More updates to follow!
