For what it's worth, I think installing a rebuilt motor is a great way to extend the life of a solid older vehicle. I've rehabilitated several older vehicles this way and have no regrets. A rebuilt 460 is probably under $2000 (they are even on Amazon now Amazon.com: PROFessional Powertrain DFA3 Ford 460 Engine, Remanufactured: Automotive and installation by a good independent shop is probably under $750 depending on where you live. Incidentals such as motor mounts, exhaust system, fuel system, hoses, belts and other can add up, but the job can certainly be done for under $3000 and much less if you have some of the skills to do some of the job yourself. NOTE: It is unlikely that the value of the older vehicle would reflect the cost of the rebuilt motor.

To remove broken off bolts, Here is what I do (and I've done it a lot). Access is the key to making any broken bolt removal work!! Note: if you are not experienced using a torch, have someone else do the work!!!

Drill a hole about 1/8 inch smaller than the bolt size thru the center of the broken off bolt. Use a premium metal cutting drill bit for this. Apply heat with a torch and then penetrating oil. Get it very hot if possible. Drill again with the next larger drill bit size and repeat. The remaining bolt piece will eventually be able to be pried out in pieces without significant damage to the tapped hole.

Good luck,

Erich

Which bolts are broken off? Depending on which ones, I would be willing to take the motor home to a 'good' repair shop and have them get the bolts out. I am not sure what others will say, but I feel that the older 460 engines were/are worth fixing. Besides I am 'not' a fan of reman engines, as I have seen too many issues with them.

I have had new crate engines installed in my service vans for around $6000 including labor. This is in Calif where things are high. Of course you still have an old radiator that should be rebuilt as well but the engines have served me very well.

As suggested an experienced person may be successful removing the broken bolts. Hopefully you have not broken off any easy outs.

Installed by a professional shop will be way more than $750. If you go to a shop that will do a professional job and will actually stand behind their work you'll be at LEAST in the 4 to $5,000 dollar range for parts and labor installed. They will be able to get you a motor from a reliable builder who will also stand behind what they sell. In the rebuilt motor game its worth paying a little more to get the job done right the first time. The cheapest way will not be a good experience.

Very true statement:

"In the rebuilt motor game its worth paying a little more to get the job done right the first time. The cheapest way will not be a good experience."

I'm fortunate in that I've found a small independent shop in rural WA that is affordable and stands by their work.

Also agree that $4-5000 is a good estimate for this job for most situations.

We had an '85 Class C with the 460. What a dog! It had enough smog gear on it to sink a battleship and a 2-barrel carb. 6 mpg at sea level and about 4.5 in the mountains.

We had warped manifolds and all the other overheat problems. The surface of the doghouse inside the cab got hot enough, even through the carpet, to melt shoe soles.

I would NEVER have another 460.

As far as just bypassing the broken bolts, I assume they held some sort of accessory like alternator or air compressor. If so, they are there for a purpose and bypassing them will cause more problems.

LittleBro
Are you sure your broken bolts are "in the block"??

Depending on which bolts are broken it may not be necessary to replace either the engine or the RV.

For example:
If they are exhaust manifold bolts, (which are the most common bolts to break), the head, (or heads), can be taken off and, (if the broken bolts can't be exacted by a good machine shop), the head, (or heads), can be replaced.

LittleBro:

Posting a picture of the situation would probably allow IRV2's knowledgeable and experienced forum members to come up with some good recommendations for what might work in your situation.
