340 w/ edelbrock 750 need to know what jets to put in the carb.

I can tell you mine, but as 'Fish says, its down to cam, weather, engine condition etc.

I ran a 750 Carter AFB for about two years and logged all my jettings -

I found .113 primaries, .101 secondaries and .70x .37 rods worked best at the track - It was a bit "FAT" at cruise but very happy at WOT.
