I've got an 85 c10 I'm looking to get a good combo for.

Currently its a 5.3 with 862 heads and ls6 can stock stall in the 4l60. Manifolds, stock truck intake and cable throttle body. 3.73 gears 27.5" tall tires. Daily light truck, I haven't weight it but I was told 3100 but I believe more around 33-3400lbs.

My planned mods are longtubes, 3" exhaust with h pipe, and a taller heavier tire(22" billets, 29-30" tire). All other things are negotiable. My goal is a fun driving truck that has an aggressive idle but still drive able.

I would like an idle around the quality of a 220/220 like I've had before in a 5.3. Stall at least 3200. Not more than about 36-3800.

My last modded 5.3 truck had 1 3/4" headers 3" magnaflow, circle d 3200 trailblazer convertor, 4.56 gears on 32" tires. Stock heads and cam. It ran and drove good just needed a cam.

Sorry I was a bit long winded just wanted to put as many details as I could think of to help with suggestions.

This is the truck as it sits currently

 

Awesome looking truck!

 

Doing so light weight it can be speced very aggressively. Make sure and get a good transmission cooler. I think a triple disk with a loose 3400 stall speed would be a ton of fun. Cam wise I would go the tried and true 224/228. I would suggest gears for those heavy wheels and larger tire. It will feel sluggish other wise.
