O.C.To answer your question direcly.
I had a Hummer with a 6.5" lift and 38 X 15.5 tires.
The Mag. SC is DEFINATELY worth it. When crusing at 70 MPH on hills, the trans never downshifts. With cruise control, the SC makes boost when needed. It is a joy to drive.
I had the SC removed because I gave the Hummer to a race series. They will always find a way to blow it up! So, when delivering it to Nasville last weekend, the drive sucked---downshift, downshift, struggle, struggle------It was work to drive it w/o the SC.
You do not need to pin the crank.
PS. The engines shown are nice but do not have the abiltiy to use modern polution controls.
HGW is looking for a project vehicle. We can get a 415 or 427 Gen III block inside the H2 that will make it a rocket. You can go to 454 but then the SC will have problems due to the cubes. Are you interested???
