without getting into the Qjet vs other carb debate I have a edelbrock 1407 750 carb with electric choke and vacuum secondaries. I have searched all over the internets for info on jetting. I was wondering if anyone had the same carb and any jet size info for for me. I have installed a fuel pressure regulator. The car has a poston S divider with a 1” spaced, TA long tube headers to a 2.5” exhaust with h pipe. Upgraded distributor and coil. I have been having a little trouble getting it tuned right and I was just looking for some info and suggestions on getting my current set up to work correctly. Thank you, this web site truly is a great wealth of knowledge for us Buick owner.
