8 inch converter questions...

Honestly dude, if you car is on motor and the stall is right, the 8" will be the ticket at the track...and with a good cooler that gets sufficient airflow (which imo you would need with ANY aftermarket converter, whether it be a 3000 10" or a 6000 stall 8") you will be fine! In fact, I LOVE smashing the throttle on the street and getting it right up to 5k...Never forget the first time I did that because I couldn't stop at a yellow the chick beside me in her car nearly shat herself! LOL

Just my opinion, but some good companies for converters- Ultimate, PTC, Pro Torque, ATI, FTI....they all seem to make a good converter, you will pay for it, but they will work with you to get it right (and don't be surprised if it has to come out of the car a time or two to get it RIGHT)

Good luck!
