Carb recommendation for a 460 Ford.

[Devinc]

I need a good recommendation far a carb on a Ford 460 engine. The engine is out of a 77 Lincoln Mark V and is going into a 78 F250 with a 4 speed trans. The motor is all stock with 8:0-8:5 compression, except for the double roller timing chain I put in at zero degrees up. The 460 has to only turn a alternator and a power steering pump, this is two less accessories to turn when it was in the Lincoln. I live at a elevation of 5500 feet and don't need as much cfm as per say sea level. The truck is going to be pulling a twin axle 18" flatbed trailer everyday around town(work truck). I would like to get the best milage possible but on the other hand I will need the power at times. The stock carb was a 600 cfm Ford Motorcraft 4350 four barrel spread bore carb(junk). I have a adapter plate to fits a standard four barrel Holley or Edelbrock carb on the stock spread bore intake. I was thinking maybe a 650 vac sec Holley with a electric choke or would a 750 Holley or Edelbrock be better or too much? Any suggestions would be appreciated.

650cfm Edelbrock carb is what your looking for. Easy to setup and easy to tune.

I'm also a fan of the Edelbrock carb.

Edit: I didn't see where you said it was a 4x4, so if that isn't an issue, the 650 edelbrock is aptly sized for what you are doing. Many guys run them for regular old 2wd pickups. If you do change elevation a little more often, I'd want a newer throttle body EFI. Just depends on how much you want to spend. Used Eddy can be had pretty easily, and I practically gave one away a 650 a couple years ago. Street driven truck, they're fantastic for every day drivability.

Coming from a guy who ran an Edelbrock 750 on his 460 in a 4x4, I'm gonna tell you they suck ass and flood every time you're off camber. I would never put an Edelbrock on an offroad rig again. I'd slap a cheaper throttle body EFI like the Holley Sniper on it. The fuel only models are seriously cheap these days for the offroad performance you get and the way I would have rather gone, but those weren't an option when I put a 454 TBI on top of mine. Once that starts shitting parts regularly I'm going with one, as they also make it easier to dial in once you pop a bigger cam in or new exhaust.

460 ?

An 1150 Dominator should work




I would use a Holley 750, vacuum would probably suit you best, very easily tune able, there is a guide to show you which color spring to use for the secondary diaphragm per weight of vehicle .




Not a fan of Edelbrock or carter carbs, I have had them work just fine, but you need a shoe box of parts and pieces to tune them precisely/properly .
