Carb recommendations for my 340

i had a 600 cfm edelbrock on my mild 340 then later swiched out to 750 holley mechanical secondaries ... my exprice was

the 600 edelbrock did have some advantages over the 750
better gas MPG I was able to get 22mpg with my 340 ,904 rear 2.76 combo

it was great for driving every day and the electric choke was nice for cold start ups

as far as the 750 dp mechanical secondaries
as far as performance it was better then the edelbrok ... hands down even with my stock 1.88 heads mild cam

but i did not get 22mpg with with the 750 and it got worse once i switched to 3.55 gears ... also i did have to keep my foot on the peddle until it was warmed up with the 750 ( no choke)


so which is better ? kinda what you value raw performance goes to the 750... as for is a daily driver 600 eddy was a great carburetor
