New shop car
Like any project it revolves around $$. Nothing big is going to happen with the winter coming.

Highest I've seen with those mods is 390rwhp(my dyno). But there is always a freak car out there.

Good luck with it.. should prove to be a fun project.
I'm curious in what torque converter options you will have, 1st gear is pretty damn high. might be looking for a lower STR converter around 3200 with a triple disk if its boosted.
I agree about the IRS though its the least of your worries, just replace the shafts with BMR units or something.
