This is an LS2 car with TFS Heads, Fast 102, 223/231 cam, and all other supporting bolt's but yet running 2:56 stock base gearing. The car made 460/420 on two seperate dyno's and the car has been 6.90's @ 103 and a 1.52 60ft. This was on a 315/35/17 MT ET Street. The car is a convertible, so it does not have a cage, my days of racing this car is over.

I'm fixing to swap the cam in the car due to being an old XER lobe design and its time for something new after 10 years. After the cam swap is complete I plan to either pull the converter and have Dave cut it open for 3200 or maybe just order a new Circle D just to try one out. Thought about swapping to 2:73's as well.

IMHO unless you are steady racing anything >3200 stall will be too much after a short period of time.
Yeah, I agree - 2.56s with a Yank 3200 is about as high as you wanna go before it starts to feel a little too loose during normal driving.

My favorite combo is my current one which is a Z06 3.42 differential with the Yank SS4000 as it's awesome at the track and was a blast to drive on the street.

My stock bolt on ls3 ( only headers and cai ) picked up a solid half second in the 1/8th with just the addition of a yank pass 3400. Drives like it should from the factory now. And it loves a shot of nitrous. Itís been a 1.48 60 but still spun a touch. Poor track prep. I think it might have a low 1.40 in it. This was a 100 shot. Valve covers never been off of her either. It was running 7.80ís before the converter. .5 is the best bang for the buck ever in my opinion. Fixing to put the same setup in my buddyís 08 and see if it will do the same thing.


This was with drag radials and a 100 shot of the line


This is on street tires. First pass with the new converter.
