Re: how to get the most from your motor...

Ok, I should have changed the converter when I had the engine out! I'll pull the inspection cover and figure out what the bolt pattern is. I checked the timing advance with the vacuum hose off and plugged, it was fully advanced at 32 deg around 3000rpm. Also it's running 2200 at 65 on the highway, s...

I will definitely try the stall converter first.
This one has 2700-3000 stall, do you think that's too high? I was thinking 10" vs 12" weight difference.
