Turn of events on the 89 gmc build. I am going to be at the peak of what horsepower that I am comfortable with on the 700r4 build that I have (build was done by a local guy with no doubts of his transmission prowess). So with that said, same said builder is going to be working a 4L80e for me, going full manual valve body, whatever else he recommends for fun... if he deems I have a need for it anyways..

Stuck on what camshaft I am really going to buy now, I had previously said the GMPP Hotcam, but now that I have ordered L92 heads

, I am more then likely going with something else.

Update, engine from the black truck is now officially in the 89 blue truck. Several hours spent trying to get the exhaust to line back up, along with some clutch fork issues, I got it all back together. Almost.

Still need to finish up with some fuel lines and put the wires/plugs back in.

On track for hopefully next friday/saturday doing some 6.0L fitments..
