Hi, so I have done some mods and am taking the GTA to the dyno at the end of the month and the drag strip in a week. Any guesses as to power and 1/4 mile times? Mods thus far.. Accel runners(minor porting), Accel dist. cap and rotor, Accel header plugs, MSD SF wires(8mm), Polished air foil, coolant bypass, SLP tri y headers, y pipe, 3inch I pipe into 3 inch Pypes Violater muffler, Pypes electric cut out in place of cat, K&N Filter in swiss cheese air box, 160 degree thermostat, Hypertech ECM chip, brand new Delco fuel filter and BBK Hi Flow fuel pump. As of now the interior has door panels and spare removed. Any input or suggestions are appreciated.

L98 or LB9?

If 350 car, with stock trans/street tires, low 14's at 98mph. Stock TPI base with accell runners wont yeild much gains due to the restriction being in the base still. headers and exhaust usually gives 20-30hp and good ignition keeps the car running as best it can.

I'd say high 13's with slicks/radials and 2500-2800 stall converter in good air.

Look for around 230-235whp/330wtq

Its a 350. Drag radials are going on before the drag strip. I won't have time for a converter before, but one is going in beginning of september. What do you think will be the best to put in, I was thinking around 2500. Also the base, runners, and plenum are getting ported in october to the full extent. TB will be milled up to 52 mm also.

2500 is good. 2800 works fine too, thats what i ran. Low 1.70's on the 60 foot in good air. Car lauched hard.. Wouldnt go over 3000 stall speed.

Drag radials with stock converter should ensure no tire spin but still the 60 will be in the 1.9's at best I am thinking. MAYBE hit a high 1.8x but depends if you can get up on the converter and get the launch as hard as it can be. If in the low 1.9's you may hit a high 13 as it sits but probly bottom 14's. With converter definately high 13's. With full port work and converter, definately should be in the mid higher 13's

I would like to hit the mid 13's at some point. I also want to try and keep it as stock "looking as possible". Any other suggestions are greatly appreciated.
