dodge truck use a q-jet with mopar throttle lever for the stock 4-v truck throttle pressure linkage
holley also has a spred bore carb that for replaceing a thermobog
I have one on the sig pic 440 in my dodge truck
I often use a chebby q-jet and just grind the shaft to remove the chebby lever,then tac weld a mopar lever on and use the stock linkage
a 2-v kickdown linkage cam be made to work if you dodnt have the stock truck 4-v linkage
you can use an spredbore to square bore adaptor to mount an eddiebroke carb on also with ease
I have both a q-jet and thermobog on the shelf along with a couple eddiebrokes
I swap intakes and carbs often,depending on the use and performance
a q-jet is hard to beat for gas milage and performance
so is the thermobog if you have a 'good working" one...which I have never had one and dont car for trying to tune one myself
dont like a holley all that much either,but this 650 spredbore manual 2ndary double pumper work super on the 440 so far
after reading the "how to rebuild q-jets" I strip them all down and find them ez to tune
eddiebrokes are ez to tune as well..set it and forget it
