After dialing in my drivetrain, with a Doubler, new drivelines, a CV on the rear driveline and rotating up my axles for better driveline angles, I've got low oil pressure and a knock in the motor developing. I do not want to be 20 miles in the backcountry when she goes. Man, and I thought I could just enjoy my rig for a while. It is a 1987 Suburban, all 1 ton. I wheel it. I've always been dissapointed with the 210 HP TBI350. The lower gears are cool, but I need more HP/Torque. Smog legal issues reduce my choices of motors. My buddy say's rebuild my 350, but that will take $ I could put towards a new motor, and the down time will be longer. I've found a few smog legal performance motors. 350 TBI 383 TBI OR, I could try to find a pre-75 body, register it, and put it on my rig. Then no more smog tests. So, I want your opinion. Vote.
