As always, this step has proven to be money well spent. Walked in the door at 250HP, left at 286HP. Plus you know when you put it in, that everything is working correctly.
Factory is 220hp. Our best pull was 290. But the timing was not set right. Once we corrected that and got the carb jetted right, we settled in on 286HP with a nice strong and wide Torque curve. Nothing like 30% over stock with minimal changes.
We saved another Pontiac.
By the way, it is also one of the more fun things you will do during your restoration process!! It's a lot of work getting these cars back in fighting shape. Consider the trip to the Dyno as one of your rewards!!
