Need a shop for engine swap

I have a 1983 110 with a 3.5 V8.

I have been getting quotes to swap to a new (reman) 4.6 (Cannibal, AB, etc.) with R380 manual, new LT230 and new propshafts. My truck already has AC.

I feel this swap is "boilerplate" and I'd like to find a shop that's done enough of them that it could be done quickly and without hiccups. I don't want to pay for "learning curve".

Any recommendations?

Its not going to be boiler plate. The enine mounts stay on the frame and you can re use your radiator and I guess the power steering pump but most everything else will be different. An early 80's v8 is different than later ones and most of those differences are upgrades. That said yes you can stick with your front cover if the oil pump housing isn't worn and re use your ancillary's but thats about it. The drive shafts, the different tcase will need new shafts. The seat box will be different between a 4spd lt 95 and the later r380. This will require everything between the bulkhead and the seat box to be swapped out, best to go ahead and source all of that now. The shift linkages are different so you will of course need all new stuff there as well, sounds like common sense but these do not come with a new trans and transfer case when you buy them and there aren't cheap.
You will need to either have a custom exhaust made or buy off the shelf stuff that will work with the 4.6 as the 3.5 exhaust wont work. Same with the transmission cross member. Its a very big job and on par with a diesel conversion as far as what needs to be bought and swapped and the hours involved. The original Zeniths would be a poor choice to run on a 4.6 as well. I'd also ditch the old lucas points and condensor with ballast resistor setup but that is my preference. The r390 tunnel cover and floors can be difficult to source. I just make new floors out of thicker aluminum to save time and money, but the fiberglass tunnel cover is unique and often hard to find and expensive. Some shops only want to use oe stuff. I'd guess to do what you are describing could be done in three days by a tech who was humping and knew these trucks, but if not expect 4-5 days and thats with zero parts delays. I could see this easily costing 15k +.

There you go. You know what needs to be done. To you, this is boilerplate.

I want all of this done by a shop that has done it before so there are no surprises. Of course I want EFI and a rewire and new exhaust. Like I said, I want a shop that's done it before, knows the parts required and can do the work without re-inventing the wheel.

I guess brain surgery to a brain surgeon is "boilerplate".. And uncle Doug is completely right...it's a pain in the ass and I'm currently doing one, thought I knew it all but earlier years add complexities that you just don't anticipate.. Earlier steering boxes don't give sufficient clearance so I have to swap that also.. Didn't anticipate it in the initial build.. Lots of poop you simply can't foresee (or forgot about) no matter how many times you've done it... And most people are looking for the cheapest..

Call Taylor.

He has done loads of the 4.6 conversions.
