I'll likely be starting my truck engine build this week and would post up my build here if anyone is interested? Nothing but it will be a full build without machine work. Engine was a strong running engine that was rebuilt sometime near 2009(bearings are stamped 3 of 2009) and not driven much after. It is already bored .030 over and still has cross hatching in the cylinders with no ridge whatsoever. The heads were in good shape and were rebuilt when the engine was and the seats and guides are in great shape. I've ordered the rebuild kit without pistons as these are in great shape. I'll be porting and polishing the heads myself, lapping and installing the new valves and valve springs myself along with seals of course. The valve springs are upgrades in order to accommodate a new, much more aggressive cam. I know a lot of people have expressed interest in engine building here so I'd be happy to post up a thread on my 460 documenting the entire build. Different engine but same principals and procedure, just bigger parts.

I like to see engine builds.

X2.

do it. I like big blocks. Is it an EFI or carb motor?

Yes, please.

do it! I love my 460 in my 89' f250.

Yes please

EFI. I'll be porting and polishing the intake manifold along with the exhaust manifolds as well. I'm also searching for a throttle body assembly off a V-10 powered Ford from '97 to '04ish. The twin throttle plates are a little bigger. The speed density system is not ideal but I should be able to port, polish and upgrade the cam(I've got a comp cams computer controlled friendly cam enroute) without it pissing the computer off too much. I'll be adding an adjustable fuel pressure regulator to bump the fuel pressure from the stock 35ish to about 44ish to trick the computer. Adding more air would throw off the fuel mapping in the system so I'll add more fuel without the computer knowing. Adding more air(porting and polishing) along with adding more fuel without the computer knowing should keep the o2 readings happy thus the computer happy.

I'll start a thread when I start the build. I'm shooting for around 330hp and 500 lb. ft. out of it. Stock it has 245hp and 415 lb. ft. so it won't be a huge improvement but it'll be enough.

Did you consider MAF as an alternative? Just curious as Garry and I have discussed it for an F series, if/when I ever get a Bronco done.

Yes! Especially interested in the porting. Am considering gasket matching my intake.

I have but the costs associated to get there don't make sense at this time. I should be able to hit a goal of a reliable 500 lb. ft. of torque without the need for a MAF conversion. This entire engine build will be done for about $1300 including a new clutch and flywheel. That is including the price I paid for the complete 460.

I read a write up a few years ago about a guy that swapped out the ecu for an AEM unit. Converted it to a MAF sefi from speed density/ batch fire. Said just by that conversion alone the 460 ran so much better. MPG went up 4-5mpg and power was greatly improved. I always wanted to efi the 460 in my 79 but the factory efi heads are junk.

330hp and 500+ is easy to get. The 460 in my 79 is 330hp 600tq. What are the specs on the cam you ordered? You really should look into milling the heads to bump the compression. a good spot would be 9.5:1

The heads are already milled. Not sure how much but I'll CC them out once I get them polished and the new valves installed. I am guessing it will be around 9.2:1 compression. The cam is pretty mild in order to play nice with the speed density so it is only 212/219 duration @ .050 and .495 lift. Stock is just about 203/206 duration @ .050 lift and .405 lift. Should be a big improvement even though it is small.

I highly doubt anyone could get 4-5 mpg extra out of any decent running 460 with just a simple MAF swap. Especially with batch fire. I've pulled a best fuel mileage out of my truck of 14 mpg empty cruising to and from Ft. Collins. To see 18-19 would be insane with this engine.

The real 460 build will be my uncles. We will be building a 522 stroker with Jon Kaase heads. His will be closer to 650 hp and 700 lb. ft. He went with a milder cam than I would have but it'll also be a truck he may use to tow with eventually. It is a 1962 Ford F-250. We will also be converting to 4wd and putting in a 5 speed.

That would be awesome.
I have a 89 F-250 that has a 460 it would sure help when I get ready to replace it.

This engine is going in my '88 F-250. It is a later model 460 from '94-'97. It has the better flowing, larger valved F3TE heads over the small valved and poor chamber design of the earlier E7TE heads in our trucks until '94. I lucked out on the engine purchase. It came from my favorite Ford truck parts guy. He told me it had 300k plus miles but ran really well and a lot of power. Said it came out of a '91 so I also expected the E7TE heads. I expected a 300k plus mile engine inside. Started disassembly and started to see signs things had been apart before. Just before I pulled the head I saw the casting of and F3TE on the heads and was already really happy. As soon as I pulled a head I knew it was rebuilt as the pistons are stamped with .030. Pulled the bearings and found their date stamps to confirm around when it was built. I bought the complete engine from intake to oil pan, water pump/all accessories to clutch for $150.

When you do build one for your truck make sure you get the later model F3TE heads. Huge difference in power potential.

That cam is plenty. About the same as what I have in my 79 but I went roller conversion.

The mpg gains was maf/ecu swap to sefi.
