Default carb 5.3 for 72 nova, help ???'s

wanna do a 5.3 swap in my 72

So far, I want to use

Moroso pan PN# 20140

Motor mount adapter plates for stock sbc motor mounts

edelbrock RPM manifold w/ignition control box

670 holley street avenger (already own, hoping to reuse) since the ignition system is distributor-less, what would i run the vac. secondary from?

stock 02+ LS6 cam

stock LS1 exhaust manifolds

Anyone see any problems here??????

Car has a fresh th350, 2000-2200 stall
3.31 gears, 235/60/R15 (26.1" tall) rear tire

Car is set up as a DD, would see use on wed. night at the local track just for fun

Drill and tap the manifold for a vacuum fitting?

Don't use the timing box sold by Edelbrock. Use the one sold by MSD. The Edelbrock box uses pills to change the timing but the MSD can be changed with a laptop and their free software. You can get a much better timing curve that way.
