Right Carb for my 340

On my 408 stroker with edel heads, M1, hooker comp, 3000 stall converter with a manual reverse valvebody.

I have a holley DP 750 with a Proform body, got 8 mpg on hwy at 55 with 4.10 gears.

With my Edelbrock 600 (4106) I get 14 mpg, everything else the same!

I use the Edel for the street, and the holley at the strip, good for at least 6/10's, probably more when I finally can hook it up!

My advice - run an Edel on the street, or maybe one of the old holley spreadbores.
