Just changed rear ends(again) finally got a 9". I have some highway gears in for the present time, which has prompted me to start tinkering with the carb again, which has refreshed my memory about the timing.
Last I checked it Liked about 17 to 18 deg. base timing. This would nuke it if I ran it as it would be somewhere around 45 deg. total.
I read up & found several articles about limiting the total mechanical advance & want to modify my distributor. I already have the allen head adjustable vac pod.
What have you guys been doing with you factory dist. to get the timing curve & base time to perform?
I have seen "re-curve Kits" before. Anyone used one on our engine?
I have a .060 over 292, E-4 straight up w/silent chain, 57 intake, 600 Edelbrock, pcv to carb, c1te heads ported & pollished w/1.78 intakes, & 1.6:1 roller rockers, headers & duals.
I still only pull 13" vac @ Idle. Not sure if that's normal for a setup like this on a Y.
I have about 12 deg base timing, & total of about 38. I only let the vac. can put in about 3 of that in an effort to keep the base as high as possible.
Thanks Fellas.
