Ok, it looks like I found my OD/converter lockup switches.

You're gonna be 350-360 -ish above, 5250 rpm.....What counts is that 400+_ft.-lbs.of torque ,between 2500 -4500 ... I know you thought this out,torque /high velocity heads/mild cam timing IS SOO MUCH FUN,in Street cars..(some of those Street cars,run deep low twelves,& get gas mileage. Technology is friggin' wonderful, at times...)

Oh, and lets don't forget the lower geared 1st of that transmission compared to the 904. :D
I forgot to mention the TQ vs RPM's part and I think I saw 400 at 3200 with this cam, intake and carburetion.
I checked it with a Holley 750 double pumper with a single plane air gap and it was around 400hp/435tq mark, but this is supposed to be a daily driver?:D
Ever since my Roadrunner/440 mag I have missed that 2 tires spinning and the car a little sideways going straight down the road and I'm finally going to get to do it again.
Controllable rear end drift is a blast, and I can hardly wait.
