incorrect valve springs... running out of gas. (fuel system)

some changes:
rear air bags They really help a coil spring car hook hard. add a bit more air to the pass side bag.

Lock out the distributor advance and run 35-36deg max . 39 is way too much and is killing the top end.
do not load the converter against the brakes at launch.
launch the car very near idle. 1000-1200 rpm max.
gives max converter flash. (the locked out timing will allow this and improve your 60ft)
13-14psi tire pressure.
carb : get rear jet extensions and notched float.
74 pri and 85sec jets. jet for best mph. give it all the jet it needs. fuel makes you go. jet for highest mph. purple or yellow sec spring .031-.035" squirters.

do not use 4th |OD at WOT.... ever. you will bust the trans.
overdrive is apart throttle cruising gear only.
do not do a 2nd gear burnout. do a 1-2-3 gear burnout. do not do a dry hop to test the bite, you will bust the converter. do your burnout and pull right to the stage. reset the tire pressure after your first pass. it will go up from the first burnout. tire pressure is critical.
shift at 6000 1st to sec, 6500rpm 2 to 3 , go thru the traps in D third gear.

I would tighten up the valve lash .022". A cam ground on a 106-108 LSA would be better.
