Carb for 340
Hi Guy's, I would like to thank everyone for posting pro or con on my question of what carb to use on my 340's, (I have built two 71's) The first one is sitting in my "New" engine stand, and If it starts and runs properly, it will sit in my 70 Dart Swinger. It will have a 4-speed trans and a 8-3/4 rear with 4.30 gear. This 340 is 40 over bore, Cam is a Crane Energizer P/N CRN-150052, Intake: Edie Torker ll. Now, what do you all think of the new "DeMon" 750 carb that looks a lot like the old TQ?
Now we're getting somewhere

For 'Street-Use', a 'square-bore' Carburetor would be most beneficial with
the 'Edelbrock Torker II'.
And 'vacuum secondaries' will make life easier.
A 'No No' Below,
Though the 'Speed Demon' is a fantastic fuel unit, those Carburetors are
designed for Camshafts with a profile of 220* to 240* Duration @ .050" Lift.
