The previous owner swapped a 350 out of a 91 suburban into the 305 tbi car. The tune was off so instead of messing with that obdI stuff I put an old carb and intake I had. It made 220 at the tire. Not bad for an engine that was only rated at 210 crank horse. After re jetting the carb, playing with the timing, removing the air filter, and 4 inch exhaust the car make 267 rwhp and 316 torque, not huge but I was impressed for what little work it took.
