Swapping X's for Trick Flows

You're on the right track in working the numbers to get a fair idea of where you are at.

Let us know how the ignition timing works out. An FBO plate would be nice to have to make to advance totals easily variable. Do you know at what RPM your distributor's total advance came in? You might want to delay that too.

An AFR gauge would sure be nice on this one....just to know where the mix was for sure.
