Hello,
So my truck has a 1 barrel carb. Its pretty weak. I'm sure it has other issues too, but I'm thinking i might start by getting a 2 barrel carb. My buddy says I will need to get a new intake manifold to get the most out of the new carb. This is for a 79 power wagon 3.7. Does this sound like a good plan? Will I have a hard time finding a manifold and carb for this setup? I'm very new to D.I.Y auto work.

THanks,
dib

 

I believe offenhouser offers a fourbarrel intake, you could consider that and use an adapter plate, or head to the junk yard and see if you can find a mid 70's aspen or the such with a super six which came out with a two barrel.

 

The slant 6 will respond to modifications, but it'll take a lot of 'em. You only have about 95hp to begin with. I doubt a 2bbl will make much difference over the single.

You're kinda limited on options but unless you need to do a lot of highway driving, the best cure for the 6's lack of guts [other than a 440]would be some lower gears in the axles. Some 4.56s will do more to give the 6 cyl some grunt than engine mods. You most likely have 3.91s now. The engine will spin faster on the highway, about 55-60 mph will be about it without running the motor to death. [Depending on tire size] BTW,you'll like 4 low with the 4.56s/31.5 tire.

Having said all that, for slant 6 hot rod parts try Clifford Engineering. [Clifford Performance?] If you swap intakes,add a header too,that'll help the torque somewhat too. Just don't expect miracles from the slant 6. Dig around through the slant 6 forums on the net and see what you come up with for performance mods. Keep torque in mind.

 

Thanks 83dodgeswb4x4 and Lugnuts. Not sure what I'll do, but it's good to know my options.

Thanks,
