I will street drive it in the future after I restore it over the winter but for now its a track only car. Initial is 16 but I can't get my total until I get a better timing light. Yes I know I can tape the balancer just haven't done it yet.
Your car is porpoising leaving the line, watch the video in slow motion. Rear tire loaded and unloaded several times. Make sure the rear shocks are long enough with the rear suspension hanging. I run Comp Eng 3 ways in 50/50 setting, Fronts are 90/10. Some folks will say you need big money shocks to fix the launch, but the CE works on my car running 11.7
You need more timing and need to fix that before messing with the carb. I run 25* initial 34* total in my 340 with the XS274S solid cam. Modified OEM distributor welded slots with one medium/light spring. Fix that and go back to stock jetting.
I launch at 2k foot brake and use 33 nozzles. I use a white cam in #2 cam and throttle hole on the primaries to delay the pump shot start. Launching at 3k you have use some of the pump shot before leaving the line. The rear is fine with pink cam #1 hole.
here's a good read for carb tuning Carb Tunning
