I have had this motor running for close 20 years in my 71. It has never let me down except for fuel pumps but that has been solved with the baffeled tank.
I installed this motor back in 89 and Street & Performance was the only company doing this stuff at the time. I got a V-6 Ferrio computer with S&P wiring harness.
My factory harness is all there nothing has been removed. All the gauges are as were form factory. The S&P harness was all plug and play with a Hot,ground and fuel relay wire and the rest plug to the motor. I wish there would have been all these choices back when I was doing mine but hey it was fun.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
