I am getting ready to put a 383 together for my 85 D100. The truck will be used as a daily driver during the summer and should weigh about 3900 pounds with driver. I would like the truck to run 12s and use some of the parts I have laying around collecting dust. Here is what I have to work with.
.030 over 383 with flat top pistons .030 in the hole with no valve reliefs. It should be about 8.5:1.
346 heads mildly ported with 2.14/1.81 valves
Factory rockers
Weiand action plus intake
750 Holley
1 3/4 headers
727 trans with shift kit
TCI Breakaway torque converter
8 3/4 rear end with 3.23, 3.91 or 4.10 gears
I still need a new camshaft and would prefer a hydraulic flat tappet. Do you guys have any suggestions for a good shelf cam that will help me reach my goals and work with the pistons I have? Also if you see anything that might not work let me know and thanks in advance.

Here is a picture of the truck it’s going in. It’s the one towing the trailer.
