Alan,

You are dead on, I'm running an F/SA 455 Olds .... it looks like the best bang for my buck would be either to "aluminize" my current TH400, or go with a properly built TH350. (I intend to run IHRA and some bracket events as well, so reliability is paramount - can't play the odds if the 200 metric is a weak link). The question of a lower 1st gear is still out there, the options are 2.48, 2.52, 2.75. I don't know whether the huge low end torque of the Olds needs a lower 1st gear or not when trying to harness it through a 9" tire. (I run Hoosier 30x9 radials). Right now, my power band does not go much beyond 5900, but a Bullet cam promises power up to 6400 or so. Don't wanna spin the heavy Olds stuff any higher with the components I'm forced to stick with in the rotating ***'y.

Hopefully I can gain enough enlightenment to get this combo right without burning thru cubic money I don't have....
