Where do I start with tuning this Holley?

Initial is 18, all in is 34, I couldn't look at my tach while I was doing this, but it sounded like it was all in by around 3k rpm.

OK. I too have that problem as well. I got around it by purchasing a digital dial-back timing light that allows the user to switch between RPM and timing. This is especially helpful when plotting the dizzy curve. They've come down in price since I bought mine. That dizzy is a nice unit. I think it has 24 deg built in. as did mine. I might still have my graphing info on it. If I do,l I'll send it to you. or at least, share what the points are.
Happy Motoring!

if you want someone to tune it, talk to andy at dyno tune USA. He's up in our neck of the woods and has produced some real bad ass cars, both EFI and carb'd once I get my poop in a group my mustang's going up there to have him tune it. If you get ahold of him, he usually can tune it on site when he goes somewhere.
