i want to take the engine out which is a 6 cylinder and put a chyrlser 360 in it with a Troqueflite a 727 transmission in it.does any one know how much i will have to mod my suspension to hold this 360 and if it is going to bolt right in. Also does anyone have answers on a heavier rearend i can bolt up.thanks kujo406

 

As for suspension,not much if any.
You will need the right mounts and driveshaft,maybe rad hoses,things like that.
What rearend is in it now?

 

You will need to change the rear end or at least the gears

 

The 8 1/4" rear end is stronger than they are given credit for. I've run one behind a mild 383/auto in my '83. It lived through numerous trips to the drags, the truck would cut 1.90 60 ft times, with ET's in the 14.30 range. Unless you're planning on a 4000 stall and a transbrake I'd just run watcha got.

If you must change it, an '85-93 9 1/4" from a 1/2 ton or Ramcharger is a bolt in. You'll have to change the front rotors to match wheel patterns.

An even better find would be a 72-73 1/2 ton 8 3/4". It's a bolt in also, and has the same wheel pattern. Got one under my '84.

All half ton front springs are the same, slant 6 to 440. No mods needed.

 

thanks for the info iam new to the truck seen really and my dad gave me this 1980 dodge. I learned how to drive stick with this truck before i got my license and now i want to build a street truck out of it. I have some time untill i acually get to start working on it. I bought a chyrlser 360 from my buddy for a couple hundred dollars and iam going to bore and stroke the engine over and i am going to buy a torqueflite tranny for it and as far as the rearend iam going to pry go and find a 8 3/4 for it just to beef it up alittle bit. But first things first is to get my engine project started off. thanks for the info again and stay MOPAR.

 

ok we gotta get the mods invovled here. some of us should work on a swap FAQ and put it as a sticky. we could collect all the info thats been thrown around and put it together in one spot where itll always be
