FIRST I would urge anyone to perform a SEARCH to look for information related to their question. The intent is to have universally agreed upon FAQs, but the reality is that you'll learn more by going through posts for the full story on any question.

Chilly,
I tried your advice and found lots of stuff on oil pressure but not an answer to my question. Maybe you or another reader can help.
I've a '78 460 with about 128,000 miles on it. I can't seem to find anything that gives a safe minimum oil pressure. Running straight 50 wt currently. Oil pressure is 60 psi cold, but drops to about 18 psi hot, at idle in gear (about 650 rpm). I wanna run it until have the money to overhaul but don't want to hurt the crank. (I also talk nice to it and pat the valve covers in the hope that helps.)

Roland and all~
I recall reading that the big block Lincoln (Ford) of 460 inch displacement was listed as developing some 200 H.P. at 2100 RPM~ the torque then would be around 500#s~ well short of the 600 or so the Hisso/Woolsey produced. I've always wanted to 'short rod' or stroke one of the 460's to see if it wouldn't be feasible to get a bit more torque at an RPM of around 1800. A turbo might be a good option~ although I have a tendency to think of them as working best when RPMs are relatively high~
A prop of a just slightly smaller diameter than the original 96" or so should work out well on the engine.
The 'stock' 460 with accessories is listed at around 750#s. This weight would be greatly reduced with the use of aluminum heads and manifold and tube exhaust headers (cast iron in original form)~ The Hisso, I think, was around 585#s, but had several hundred #s of guns and ammo mounted about it. The weight then shouldn't be an issue.
I'm assuming that there are boat 'bell housings' readily available which incorporate propeller drive shaft systems for the BB Fords. They definitely were made for the 427s and other more exotic Fords and the bolt pattern might well be identical.
All in all, it might be a feasible way to get a 'direct drive' engine onto the front end of a SE or SPAD? Any comments appreciated~
I think I'll try to accumulate a few more ideas and unless I find the premise completely disproved, I'll soon be in the market for a few components~ especially the boat bell housing adaptor~ If anyone knows of the source of a marine adaptor for the BB Ford I'd appreciate a lead~
Best to all, Lee. Nieuport http://www.theaerodrome.com/forum/members/nieuport28.html
The above was written in the address listed above. This has caused me considerable trouble as I had not studied the Ford, Mercury @ Lincoln 429-460 engine to even the smallest extent. But I have been studying it intensely the last few weeks it was originally place in the “theaerodrome” August 20 1970 but I and others paid it no attention. But I have in the past month done a lot of research on the 460 version. Especially the one with fuel injection as an aircraft is a 3 dimensional vehicle. Trying to get a carburetor to do this was a problem until someone solved the fuel shift problem. Finding that aluminum heads and manifolds were very available was very surprising to me!
Question (#1), has anyone to this groups knowledge tried to place a properly prepared 460 either with E.F.I. or a carburetor in an aircraft?
Statement (#2), it is also obvious that the engine has enough background to support a dry sump system, tubing exhaust, and several other things of importance.
Statement (#3), the engine this would be interesting to replace would be the World War #1 engine the 718 cu. in. Hispano-Suiza V-8. To do this would require a torque of 617 ft. lbs. at an output of 235 horsepower at 2000.This would require a gear and pinion of sufficient strength and to reduce the r.p.m to the 2000 required at the propeller.
This engine, Hispano-Suiza was a troublesome engine, as probably they all were, at that time. With 180 degree crankshaft (unbalanced primary) and the usual secondary shake. Oiling problems due to a design error of not putting an oil pressure relief valve on the oil pump output this blowing out the oil lines.

Aircraft using the 429-460 engine.

I will try to find that book but one that old is not very easy. I have books back to 1907 on the balancing of engines,V-8s in particular, but it took me about 5 years to find that one. However you just never know what will just seem to pop up when you have given up.
Yours, M. L. Anderson :)

If you make up your mind that the engine has limits of exhaust
ports, iron heads, and stock rods and let it go at that you can
relax and enjoy the ride.
Just dont expect it to run like you spent a lot of money on it
and let it go at that. Its big enough to have a problem with
the bite and pull hard so dont try to destroy it.
If you get used to the way it runs so you can feel what its doing you will feel it start to feel "ready to shift" around
5 or 55 hundred so dont get heroic - it will go further than that
but it will eat a lot and spoil the fun.
Be very sure about oiling and if the valves loosen - lash them
tighter - so they dont loosen and hammer, and just enjoy the
touch and feel of the big block.

Intake valve size doesn't have to be compelled to be exaggerated at this level, untainted valves ar steered over heavily used stockers
Port work on the exhaust aspect ought to be thought of necessary at this level. Thermactor removed, bowl intermingled to the larger seat, casting flash removed, exhaust bolt boss two-dimensional. the higher the work, the higher it'll run........:)

Hey guys I'm sure you've all heard this a million times, but I just got an 86 f250 with the 460, and I live here in the great state of California... Supposedly everything on the truck is smog legal, except for the carburetor. I've looked on summit, jegs, and searched around on here but have found no smog legal carb. Does anyone have any hints or anything on where I could find one? I'd really appreciate it

I have te same truck more or less




These trucks came from the factory with a Holley, so it is smog legal if it was originally sold in Cali and still has the air pump and the associated parts. Dave

You're probably better to start a new thread with a title that says what you are asking, you'll probably get more responses.

Carb Trade

Send me a nice 3310 Holley 750/780 4150 or a 830,850 with fuel line and I will swap you my factory smog legal Holley right off my running truck that has no issues. I am thinking of a stoker with alloy heads down the road and can use the bigger carb. My truck is a one owner 91K mile piece that is mint and the carb is running perfect. PM me if you are interested and I can send you pictures with the air cleaner off. Dave
