 Subject: 3.9 4 barrel manifold

Message:
I found a 4 barrel intake manifold for a 3.9 in a junkyard last weekend. There was no carb on it. I wanted to know will the computer still work on my 87 dakota if I bolt it on with a Holley carb ? I need to know if the wires that run to the stock carb need to be hooked up for the ignition to work.

I would say yes that the cokmputer will still run fine if you change it. Here are the part #'s listed in my 3.9 preformance book for the 87-91 dakota. The number on the second line that is 7 digits long is the part # to order direct from your dealership
Holley P4781 - 850 cfm 4Bbl
P4348232 Mechanical Secondaries,
double accelerator pumps
Holley R1850 - 600 cfm 4Bbl
P4349227 Vacuum secondary
Holley R3310 - 750 cfm 4Bbl
P4349228 Vacuum Secondary
Holley R3418 - 855 cfm 4Bbl
P5249808 Vacuum Secondary
my personal recomendation would be the 600 cfm carb, will cost less and give you more than enough preformance.

I was planing on using an old Holley 450 or an Edlebrock that I have.

Don't be surprised if your truck runs like a sack. With no other mods you may drown your engine. Even some v8's are known to become boggy because of the 4 barrel. It's especially common with some RT's. Many complain they lose lots of bottom end.
Then again it may perk up a little.
Good luck.
