352 carb questions

Hey, brand new to the forum. I have a 65 f100 w/352 2bbl, and am interested in going to 4bbl. The thought being that a spread bore carb can get better milage on the primaries than a 2bbl. Is there any logic to this?

Re: 352 carb questions

it was true when my friend did it with his 70 cutlass with a 350, he put an edelbrock performer intake and a stock quadrajet and increased his mileage by 4 mpg on the highway.

It definately can be, but... you've got to keep your foot out of it.

Re: 352 carb questions

Thanks for the replies. We never ever knock the cars we grew up with, my dad bought my f100 brand new, its never been out of the family. Rebuilt the engine about 10,000 miles ago and hope to get new paint this coming spring. Also 4 mpg can be huge considering our pump prices here in Long Beach Wa. are at $3.19 for reg. right now!! Any leads on fe 4bbl manifolds? Thanks, Don.

$3.19 for regular !!!!! and that would be for a gallon. i wish. ha ha. here in australia we pay around $1.25 per litre !!!! not nice.. anyway. due to tha higher air speed thru the small spread bore primarys you can get a little better mileage if your gentle on the throttle. use an edelbrock performer or equiv dual plane manifold with no or smallest possible spacer under the carb to boost your low/mid torque and economy. you'll also save a heap on weight compared to the FE iron intake! cheers.
