Background: I am the proud owner of a 63 F100 Crew Cab, built by Armbruster Stageway (Coach Builders) in Fort Smith AR (which is still in business today.
I’ve had the truck for about 18 months. The information I got from the PO, who got it from another PO was that it was built for and used in the oil patches of Northwest Arkansas. It is a long sucker, measuring in about 19 feet. From all I can find out, the truck is unusual even for a 60’s era crew cab in that it’s an F100 (Most apparently were F250s) and the truck has a LONG (wrong) bed, which is correct for the truck. (Apparently most known conversions had to short bed, to keep from having to extend the frame.
Now that I have my new shop completed and inside room to work, I have begun the process of taking the truck apart for refurbishing and rebuilding.
We should have the body off next week so I can begin cutting some of the rust out. For those who don’t know, they use (or at least they did) use a lot of saltwater in the drilling process, therefore there is a lot of rust to remove and panels to replace.
Originally a Y-Block with 3 on the tree, the truck currently has no engine or transmission. When the PO bought the truck it had some kind of a Pontiac OHC engine in it. Therefore I am starting with basically a blank slate.
I am basically a traditionalist and would normally be only considering a Y-Block for the truck, but I would like it to be a cruiser with the ability to tow at least one of my other slicks to Slick Stock V. It will cost me in the neighborhood of $2,000 to have a Y-Block built.
My thoughts at this point are running toward the following:
03-07 Crown Victoria front cross member, disc brakes, power R&P, etc.
Lincoln Mark VIII 32V OHC engine and AOD transmission (280 HP vs 200 HP for the 4.6 PI engine) and aluminum block vs cast iron (as I understand it).
And possibly the Mark VIII IRS, or use the Crown Victoria, Mustang, or Explorer 8” differential, possibly with the leaf springs.
The Mark VIII power plants are relatively cheap ($700-1,000) for an engine in the 50, 000-70,000 mile range with all accessories and transmissions about $400. I have located one with front end sheet metal damage in Austin for only $900. Only problem is that it is a little high on miles (120,000) although it supposedly was owned by a lady my age, whose son wrecked it. That would give me all accessories PS pump, A/C compressor etc, etc. plus the wiring harness and computer, plus the tranny, and IRS.
A major expense will be one of the Ron Francis wiring harness kits at about $900, but that appears to be so simple that even I can figure it out
A couple of members are currently working on a similar setup and I’m following their progress.
I could possibly consider the Jaguar front and rear suspension, but can’t believe those would be too plentiful around North Louisiana. I’ve seen several on e-bay in the $500 range for a complete front suspension or the IRS.
I would appreciate your thoughts, comments and free advice on this potential swap.
