i have an 85 trans am LB9 and this winter i plan on getting a few bolt ons for it. I want slp siamesed runners, an SLP CAI kit, SLP stainless emmisions legal headers and an SLP air foil. I already have a dynomax cat back and a catco high flow converter, the car has just been tuned up as well with accell 8.8 mm race wires with matching cap and rotor. what would i run in the quarter after the mods as well as now? remember i have an 85 TPI so i got the L98 cam

huh?? no way i raced my friends z28 TPi on a quarter mile stretch and he ad a g tech in his car, he ran a 15.3 at like 92 mph and i was a nose infront of him. no way your gonna tell me that my L98 cammed TPI car runs the same as most TBI autos, and please dont respond by telling my that TBIs run mid 17s becouse one in proper tune should be capable of low 16s high 15s even better with a manual so lets keep it real. i just wanted to know how the SLP set up would have worked out for me....

 

You will be in the 14's no problem at all. I am guessing that you will be in the low 14's with the combo that you have with a good launch. 90Iroc is right Auto TPI's are slow but those are with the peanut cam. He has the good (stock) cam in his car so if you shift right you are good for 14.3ish. Just my guess. Good luck and post your results.
