460 into the 71
im building a 460 power house to drop into my 71 f250
. any hints or tips or anything i should be aware of for those of you that have done this before?
Also after i get this in im going to want to update the AC system in it. I want to convert it to r134a but have a few questions. 1 will the factory compressor work with r134a or do i have to get a different one, 2 does anyone out there make custom ac lines? i havent been able to find anyone here in okc oklahoma.

Horsepower TV (on Spike) did a budget build of a 460 a few years ago. Then they took the same engine and built it up with higher performance parts. The video series is worth a look.
Really? No one makes custom AC lines out there? I figure you can contact Nostalgic Air, Old Air Products, or Vintage air and they can spec the fittings and provide hose stock. Then all ya gotta do is mark for length with the fitting clocked in the proper position and find someone to crimp and test them.

I installed a 460 in my '68 F250 in the early 80's and it's worked out great. I had a slide-in camper and pulled a big boat and needed the power. An RV cam and duals or headers are a help. Be sure to get 8.5:1 or 9:1 compression pistons as the stock ones, in the mid 70's engines, are 7.5:1 and run like crap. Don't ask me how I know. You're not going to use the York compressor with the 460 anyway because it doesn't fit the mounting. The long round one is the one that comes with the 460, and that's what I used. Any shop that builds hydraulic lines can make custom hoses for the A/C if you have your original fittings.

The easiest way to install the engine assuming we are talking about a 2WD is to use factory mounts from a dent. They bolt right in. You will also need the truck manifold for the right side or headers. I bought a set of Hedman headers for a '74 F100 2WD 460 and they work just fine. The cost was $225 & that was tax & all. I have a complete set of the factory mounts. If you are interested pm me. I picked them up for my swap & ended up custom fabbing mounts. The CV IFS was happier with custom mounts.

There are 2 easy mods that can be done to gain power. Swap out the heads (assuming your engine is '72 or newer) for c8ve, c9ve or d0ve heads. This will bump your compression from 8:1 to 9.5:1. Install a timing set for a '69-'71. Starting in '72 the cam is retarded. The early timing set will put the cam back at 0.

well im keeping the stock d3ve head which from what i read are next best to d0ve heads and im having them machined a lot and still keeping my compression low for the procharger. all forged parts and yes with a 71 timing set up. Go check out car crafts 460 build and thats how im building my basicly but with a procharger.

Well, the D3 heads are around 2nd from the bottom in the 385 series head hierarchy; and that isn't good. Don't get me wrong, you can get them to run decent; I have had them. But why put any $ in them when you can find a set of used aluminum cylinder heads that will out perform even the best D3 heads? It's your build and your $ but I would do away with the procharger on the D3 heads. I would look for a nice set of used aluminum cylinder heads and consider a turbo. Turbos are not so hard on parts. I know of one f100 in southern louisiana that uses a stock 2 bolt block with a cast scat crank; 545 cu in, with twin turbos. This truck made 1200 hp at the crank with over 250 passes at the track in the 8:80 to 9:10 range. Point being it is not always the parts; tune has a WHOLE LOT to do with it. What tranny you plan on using?
