I've said it before.. Perry if you were closer I'd help you fix that truck up. Worked for GM as their truck Mech up until around 92, so isnt much I cant do to them...
I JUST pulled the cab and flatbed off my dually yesterday.. THe Dually, Betty, and about 3 grand are all about to become one.. I have to have a dependable truck to haul bees to Maine, so its getting overhauled from the ground up.
The 489 is getting removed... it was GREAT for pulling stumps but at about 7 mpg I dont think it will do well on a 2400 mile round trip... so the roller cam 350 in Betty will be used with the newly rebuilt 700R4... not as much torque, but it gets closer to 18mpg out on the interstate...
Going to coat the frame and start from the ground up. Already has new tires on the dually so.. Stainless steel break lines and hoses, new hub bearings, all new front end parts, new gas tank and fuel pump, etc, etc... I'll keep the TBI in it.. I really love the TBI fuel injection system... a lot of guys dont like them because they limit out at around 4K rpm... works good in a truck meant for towing though. A Harris chip and minor mods will see it close to 300 HP and still get good mpg comparatively.
Headed up there to work on it right now in fact...
