I just got my 88 chevy suburban R10 4x4 with the 5.7 litre chevy 350 tbi motor. I have a flowmaster 40 series that i plan on getting a local austin shop to weld on, infront of the drivers side rear tire. I was wondering if anyone here had experience with the Tbi motor, and what should be my next upgrade? The truck has mickey thompson 32's on it now, and I am wanting to build a mud truck,with eventually a lift kit. I am looking for any suggestions where i can start on a budget. I was thinking heads intake manifold and cam to start. I have never had a Tbi motor, mostly carb motors, and am open to advice or suggestions.
