Here is what they did to boost power by 50%:
* Replace secondary main jet with larger item
* Set dwell to 51 degrees
* Swap distributor mechanical advance secondary spring
Quote:
in all cases of this sort, the points should be set by dwell rather than by guess or feeler gauge since improper point setting can negate much of the effect
Of course if you have
Electronic Ignition you don't have to worry about points and dwell.

Back on the street, the added power at the bottom end wasn't especially noticeable until 3500 rpm, though it made itself apparent by a smoother take-off. It was the secondary tip-in in the lower gears that gave the clue that something was different. The conjunction of the quickened advance and the air/fuel curve now matched better, giving a more efficent burn and the difference was one that could be felt and even seen. Getting onto freeways was no problem...Mileage suffered not at all expect in the top end
