first time to track with Vortec motor

I have a 350 bored .060 over, vortec heads that have been milled .018, LS1/6 springs on it for a .550 lift, voodoo 268 cam, 750 speed demon carb w/vac sec., full MSD ing. (box, wires, dist.), TH350 built for 550hp, and a crappy 1800-2000 stall. Street tires also.

60'... 2.362; 330... 6.384; 1/8... 9.508@79.45; 1000... 12.192; 1/4... 14.468@99.16

I know my 60' is horrible so you dont have to tell me about that. I have an excuse for it though. I havent installed a throttle stop on my car yet so i cant just slam the pedal. The pedal travels further than my carb. linkage allows so i can damage the carb by flooring it. That was me shifting at 5000 RPM also. My dad ran right before me and he got a horrible 15.9@93 in the 1/4. He left it in auto and it shifted to second at 3500rpm and then right into third. Just thought i would share

Re: first time to track with Vortec motor

It'll make the gains that much more sweet since you have a baseline to compare to should be a 12 second player with tires and WOT from the get go.
