Default 503 track times

Well went to the track today. Went 12.86@110.91 on my new setup. Here are the specs. I had this cam ground up close to 503. 226/230. .540/.545 with 1.6 111 sep. Mac headers, ls1 lid with ram air under front bumper. 36lb inj. Home ported heads. Electric water pump, 3.73 rear with 19" 05 vette wheels. Car went 13.69@104 before changes...I DONT HAVE A STALL YET!!!! crap. I will put in a 3600, probably this Rev Max i have read about, half the price. Anyone running one? Let me know how u like it! Or dont like it! So anyway thats what i ran and with a stall i figure maybe .5-.6 gain yes? Could be knocking on the door to the 11's. If not i will just put my ZEX wet shot on it. Thanks guys.

Make sure you get a stall with anti balloon plates for nitrous use.

Id recommend a 2800-3400 just to keep you in your cams sweet spot. I ran 12.4's with the 502 cam and a 2800 stall with unported heads. The 503 is a great cam for an off the shelf cam.

Ya i need a stall! This thing is lazy as hell coming off the line. But after the 60ft this thing pulls HARD, especially on the top end. Think i might go with the Rev Max 3600.

I run an edge 3400 after my th350 swap. They set the converter up for the car and im real happy with it. U get a nice converter in the car and you will be happy with it.
