440-3 Starts then dies
« on: September 18, 2021, 04:54 PM »
i got a 440-3 and my psi compression is the fireing order is differant then what it actually is on left side ( drivers side) numbered 1, 2, 3, 4, front to back 1 is at 115 or 120 psi and 2 is 115, 3 is 115, 4 is 125 or 130 on the right side the numbers go  5, 6, 7, 8, front to back 5 is 122, 6 115, 7 115, 8 is 122. it starts up then dies when i step on gas or it dies in 1 minute to 30sec. i had to put in 3 new pushrods 1 in 8 one in 5 and one in 4. i had to use the old lifters do to being broke down in a walmart parking lot and the manager threated to tow it which would've left me and my service pet on the streets. but got it moved by someone helping m tow it with his truck. Now my question is what might be the problem in why it won't keep running? mind you i know the torque converter and transmission needs replacing which takes a tr727 trans. the spark plugs are bosh and they where 1 month old when put in storage 11yrs ago. having o drive with oil going into exhaust manifold and having 2 pushrods taken out so it wouldn't damage the valves and go through the pistons. so is my psi pressure good or do i have to go buy new rings again after returning them so i could get right liftrs which i never got on time?

since nobody else has replied,and i will say i am not an engine guy,you might have screwed yourself D:oH! all that aside,since you sound like you can work on your stuff too or learn to.if it was me,i'd go find an older looking RV park n talk to them bout towing it in n putting tarps under n making sure any fluids end up in containers.then tear into it.but after rods n lifters being fixed,check out http://www.dave78chieftain.com/Dodge_Electron02.html for your ignition electronics.Ballast,ECM,volt reg n such.good luck on trans.but it might be as easy as a fuel delivery issue,or old gas.

justtrucken, your post is kind of confusing but the compression that you are getting is sufficient to run the engine. A Dodge engine cylinders are from front to back, 1,3,5,7 on the driver's side and 2,4,6,8 on the passenger side.

Kind of a basic question, but something which has been found to cause this, including myself... have you changed the fuel filter?
