My last 12 second car was a 25 dollar 360 that I put another 975 into it. The tranny was a used - untouched 727 from a pickup. Yeah, we were in same company running 12's. Again, not picking on you... just stating the facts. I doubt I ever build a 410 stroker, but if I do, it won't be a 12 second machine, unless it's in my B250 Van :D IF you can't build it, spray it. :)
