Blown 345

I have a 75 Scout II w/ a blown 345 engine.the pistons, and cam are junk, but i think i can save the crank and the block looks ok. Is it worth trying to rebuild the engine or would it be a better idea to convert it to a diff engine? If it helps it has the 3 speed auto tranny. I want this thing to be a driveable off-road vehicle (as apposed to a trailered) and i live in CA so smog laws here are a pain. I saw Jim's idea of a 500cid Cad engine, cool but more $$$ than i got.

Re: Blown 345

Hi. I wrestled with that question for a couple of years. I thogut about putting in a 4 cyl Cummins, a GM 6.5 TD, a chevy 400 or 350. Anything is going to cost money. You can cut the cost down if you can do most of the work yourself. I decided to bite the bullet and have a very respected (and a little expensive) engine rebulding co here in PHX rebuild the engine, a good company build my 727 trans.,and my son-in-law and his dad are doing the installation. If you put in another engine, you have to get adapters to put that up to the Scout trans, or else put in a different trans too. I believe Advance adapters in CA have an adapter for the chevy 350 to the Scout 727 auto trans. Then you have to get a chevy engine. I want my Scout to last forever, as my 27 year old daughter wants to use it and will take care of it. How much work will your engine take to get back on the road? IH parts are expensive , but probably most are available. How do you know the pistons are gone? Does the block need much work? If you're interested in more information, e-mail me at [email protected]

Re: Blown 345

replace it with another 345 engine. They are readily available, and if treated reasonably you should get 250 to 300,000 miles out of it. The 345 is a TRUCK engine as in school buses and medium duty trucks. Remember, anything less is just a car.
