Here's an example of a 3160 lb. footbrake launched ride slowed every week to run low 10.0s with a sbc under the hood backed by a 1.80 1st gear glide that leaves with a best 60 foot to date of 1.27 and has run 9.77 @ 138+ with a manifold having less plenum volume than yours and no 2" spacer

What size motor, converter, rear gear, shift rpm and trap rpm. From that 60' I'm not even in the ball park. What carb and manifold is on it? If its top secret stuff PM me. LOL!!
