The setup on the lux will be 4.8s in the diffs 4spd box with 253 v8 with 33s Question will the 4spd handle the v8?

The petrol 4speed struggle to hold themselves up but the deisel box appear to cope alot better. Im running 253 with 4.5's on 35"s and haven't blown a deisel box yet. I used to run a 253 with 4.8"s on 35's with a petrol box and spat about 4 boxs.

A high compression 253 produces 138kw@4400rpm and 355nm of torque @2400 rpm. Compare this too what the highlux motor does and you will get a better idea of what will happen.

I had a 253 in my lux with a 5 speed did burnouts 6500rpm between gear changes (worked motor) I was hard on it never had a problem.
But then you get them blowing up under a little pressure.
