77 stepside street/strip rat build

[steigst]

Hi Everybody. I’d like to start by thanking the community for all the great information shared on the forum. I’m building my first rat motor and would like share my combo and get some constructive criticism.

The build:
454 bored .030 over
Speed pro forged 27cc dome pistons (haven’t cc’d heads so 10ish:1 CR)
Reconditioned rods
Stock crank
All ARP fasteners
781 heads, .219 int .188 exh valves
60204 Lunati Voodoo flat tappet w/ matching springs
Lunati Voodoo roller rockers
Edelbrock RPM Air-gap intake
Holley 850HP series
Still undecided on ignition…. Probably Mallory HEI distributer with a 6al box.
I should note I picked up an edelbrock c66 dual quad setup with two 1407 carbs I would like to swap on if I ever take the pickup to any shows. Not the ideal setup but it would look filthy if I could get it tuned.

Going into 1977 Chevrolet Stepside 2wd ~ 3800lbs but dropping and shifting weight where I can.
3.73 rear gears, a TH350, GM 12 bolt, and probably going to run cheater street slicks.
Stock front suspension dropped 2”. Air shocks in rear with traction bars and 1” drop shackles.

Any advice or criticism for my combo?
