IS this engine worth anything? Is it anything special being the last of the high horse 460's. I have the rad tag that shows it at 365 BHP. I thought maybe it was a decent 460, but I don't know much about this engine or year. Would it be decent just cammed up a bit? What would be the good and bad with this particular year 460? It has 35k miles on it.

 

A '71 will have 10.5 compression. The later motors had taller decks, bigger CC in the heads and other changes that caused the power to drop. The biggest change in the numbers was the change from "gross hp" to "net hp".

Your 365 is a number picked pretty much out of the air by Ford to make the power "fit" what they wanted marketing wise. Gross ratings were done without accessories, stock exhaust etc. Net was supposed to be as installed in the car, with all the air cleaners, mufflers, pumps etc.

This is a good discussion about engines from that time:

IMO that would be a good 460, and would probably happily take a more aggressive cam. Valve seats might be an issue though, especially if you are going to run it hard.

This is all 460 all the time, and even though it doesn't directly address your engine in it's stock tune, you can get an idea of how things go with a bit of work on the 460. Hint: They go quite well

Another one where someone copied the stock specs:

It should have the DOVE heads on it. If it runs and doesn't smoke or use oil ? In my area it might be worth $350 to 400 dollars.

 

pretty much agree with above posts, i on the other hand hate mystery engines, so i violate all of them. I have seen a lot of shady crap or pennzoil sludge machines. 429/460 and clevelands have good potential for power with stock parts.

 

These earlier 460's are only worth 350.00-400.00? Wow....complete 460 running with carb to oil pan 400.00

 

An old friend of mine has a '78/'79 Bronco 4X4 with 38" mud tires, that he uses for daily driving and pulling his swamp buggy (on a trailer) out to the hunt camps.
He originally had a 351 in it. Gas mileage wasn't good at all.
He rebuilt a 460, kept it pretty much stock. He swapped it in-place of the 351; he said the Gas mileage was so much better, either pulling the swamp buggy or just driving back and forth to work.
I guess it was a better "power to weight" ratio.


He still drives that thing today, good 'ole reliability.

 

I have been all over the map in the last couple of months, plenty of articles to read on these early engines and different opinions from all directions
My understanding is the two engines at some time shared the same 385 series block, but the 429 came to a halt some time down the road, yet the 460 lived on
The mention of horsepower being rated different can be confusing, but my understanding is that the so called dove heads were made in different configurations, some being better than others on a wide scale, so to increase my knowledge I will follow the mentioned links
There are very few known motor heads in my area on these engines, so I’m not fairing so well at the moment
I pulled a running thunder jet 429 4V from a 63 F-150 unibody a few years back and it now lives in an ARCA/ Nationwide chassis
One issue after another due to trying to stuff a size 12 foot into a size 8 shoe, now leaves me looking for specific knowledge from someone that knows how to make this engine live with an external oil pump, wet or dry sump system
I don’t need a 40,000 engine in this street machine, just a way to make the oil flow in a shallow front section oil pan that I will have to fabricate myself because a custom pan and oil system could be up to 3,500 or more over the counter in race form
Hopefully someone here can calculate the flow rates on a pump to get me over the hurdle, so I can start fitting the body down over the roll cage and get her Road worthy by mid year
Once I’m able to start loading pictures, since I’m new to the forum, I’ll share the 63 truck project that is ready for glass and lighting thats been chopped channeled and stretched over a 2007 crown Vic P71 chassis and measures about 50” to the roof on stock suspension, can hardly wait to turn some heads
Thanks for allowing me to join this group, I’ve already learned a lot in just a few weeks and had to join and share if possible

 

Still waiting for those pictures Randy!

 

Sone voice in the back of my head is saying the motor mount bosses on the Lincoln were different. Wrth researching.

 

Different than what ? The 351 ? Yes. Than any other 429/460 block ? No.

 

The early 429/460 heads also had screw in rocker studs, another "plus" I don't recall when they went to sled fulcrums though.

 

The block casting number is the same, so the block is the same.

Block casting number: D1VE-6015-AB, A1B or A2B - internal balance.

1971 Thunderbird 429 // 1971/73 Ford/Merc Passenger Car 429 // 1971/78 Lincoln/Continental Marks 460 / 1972/76 Thunderbird 460 // 1973/76 F100 460.

1973/78 Ford/Merc Passenger Car 460 // 1973/78 F250/350 460 // 1975/78 F150 & E250/350 460 // Some 1979 F150/350 & E250/350.

 

I was talking about the difference between the Ford an Lincoln 460, as was the subject. As I said, not sure

 

Ford - Lincoln, same engines for both. Last true Lincoln engines were the 60's 432-462

apparently the motor mount bosses are the same but there are some differences.
