I would like maintain a hint of mileage at least. I'm currently running a 750 cfm vacuum secondary Edelbrock #1407. I'm chasing a stumble and have gone through it several times and am looking to move on and try something different. I'm considering an Edelbrock AVS. Thanks.

I've had GREAT responce out of every Eddy carb I've used. Tom "Everyone should believe in something; I believe I'll go fishing." -Henry David Thoreau Men and fish are alike.

I'm a HUGE fan of the Eddy/Carter AFB's, but if you want fuel economy, you're off to the wrong start with both your vehicle AND carb choice! FWIW, my 79 PW had a 360 with an Eddy 600 and I got 8mpg on a good day. And I drove this thing daily for a decade,and 8mpg was about it! It was FAST and it was RELIABLE to a fault, but HUNGRY!

A small eddy maybe a 1406 (600) but make sure w it that the choke is right, the tension and esp that the "pulloff" opens it a small correct amt when it starts. If you have a spreadbore I'd have Demonsizzler prep you a thermoquad. I had one on a C boat 440 & it ran good and pulled hard considering. EDIT meant to say had a PO installed 600 on the C body Last edited by RapidRobert; 12/05/10 09:00 PM. live every 24 hour block of time like it's your last day on earth

Your best bet would be a spreadbore style carb, The TQs are good on gas but they can be finicky if not set up right, another carb that will do well is the Holley 6210 650dp spreadbore, it will be easier on gas then a squarebore, but it'll have that kick in the ass feeling when you get on it & open the larger secondaries, i had one on a mild 340 back in the 80s & it was a tire fryin mother. 75 Duster, 451 10.87 @ 123.58 NA 97 Z28 6sp., 12.01 @ 115 on a 100 shot 71 Swinger. 360 magnum. 12.58 @ 105 78 cutlass, 469 BBC. 12.70 @ 108 on street tires. http://www.youtube.com/watch?v=Z2kqNmMfheU

All those things left out affect as a whole. Especially, a short stroke smallblock with a biggish carb. A 650 would help driveability. BUT, I would try dialing in more initial mech. advance and some carb tuning. Are the idle mixture screws responsive when adjusted?? R.I.P.- Gary "Coop" Davis 02/09/68-05/13/04
