I'd use a Quick Time. Engine mounts will be a concern. You don't want the
oil pan to be lower than the frame. Also, total engine height of the motor might be a problem if using an air gap intake. The engine will torque alot under load. so seriously think about a cable throttle instead of solid linkage. Less change of binding. Also, your front to weight ratio will change, because of the added weight on front end. You will find that 3.73's will make first gear a tire burner. Seventeen inch wheels with 315 35 17 tires by Nitto NT555 is a good summer tire. Tread depth is 10/32 versis the NT555R which has 6/32 tread depth. Also the R series is a softer compound than the 555's.
Sorry for the long post. I looked for a wee bit of time to find a good set up for my big block flat track engine.
