Once torque drops the engine isnt really doing much work from that point on. The spark advance is approx 12-15 degrees at that point. It takes a pretty perfect engine set up to get the HP out of one of these on a rebuild... A driveway rebuild may be 60-70HP at best , same with ignition , takes some massaging to make them perfect . I probably built a few hundred before i got a perfect one !! |

Re: advance curves
I don't mean to hijack the thread but I have somewhat related question: do I need to make any adjustments to timing when I use 89 octane gas?
