if you've conquered your traction/hookup issues, you're WAY past 12-second timeslips.
Haha, We'll see.
As for 12s, I was talking shifting a 3 speed 400 at 5500 rpms, with the miniscule torque converter I have now, and 3.08 gears.
Looking at different options for torque converters right now. I wanted to retrofit my 400 tranny with a switch pitch conversion and torque converter but the company's web site doesn't seem to be up any more.
A lot needs to be beefed up before I can try leaving the line at anything above 2000 rpms more than a few times.
FWIW, i'm also using MAXIMUM OVERKILL(blown big-block), to reach 12.00 times. just doing it differently, and more mildly(RV cam/junk heads/2-600cfm carbs/2.69 rear gears..and a 6-71 supercharger.
Maximum overkill is fun. That sounds like an interesting buildup. What are you putting it in?
