Project -underfunded - '68 shortstep/carb'd LSx/200-4r build

[68GMCCustom]

I'm finally to the "mostly clean" part of my build. I am doing a frame up on my '68 GMC custom. Cosmetically it looks like a Chevy with a '68 Chevy grill, though my plans are for no markings on the truck.

I will be installing a genIV '09 LY6 6.0L crate motor (using the ECE kit) with a 200-4r trans backing it up. The LY6 is an iron block 6.0L with VVT (variable valve timing) and the high flowing L92/LS3 style rectangular intake port heads. This 6.0L will not be efi...it will have a Holley Street HP 750 carb sitting atop a GMPP LSX/LS3 dual plane intake with an MSD 6LS-2 to read the sensors and fire off the factory coil packs. Comp has recommended a .224/.228 @ .050 and .566/.568 lift on 112 LSA tho I've been thinking bigger. The 200-4r is built to handle 500+hp and has a 2500rpm stall convertor.

*edit - cam went bigger! see attached:


I also have the CPP (Western) 2.5" drop spindles, tubular upper control arms, 1"/4" drop springs, drop shocks, adj. panhard, and front and rear sway bars to upgrade the suspension. I also am wanting to add rack and pinion steering, bigger brakes and rear discs, and a vintage air. As for the body...other then the addition of a cowl induction hood...the paint and body work will have to wait for me to pay off the powertrain/chassis build.

The perfectly good running and looking truck I started (after setting the body on a '72 chassis a few years ago) with:
