Found some cool pictures

I was surfin' the other night and came across some pictures of the 534 seamaster engine. Have a look!

I wonder what that motor would really do with todays technology. It is basicaly a industrial 460 from what I have read, and I imagine like most other early industrial motor it would only spin 4500 rpm max. So I guess boost would have to come on really quick, and peak about 2000 rpm to 3500 rpm.

Don't know where you read that, but your information is totally wrong. The 534 is part of the Super Duty family. They are completely unique to themselves, and share no parts with any other Ford V-8. The design is a bit similar to an MEL, but they are much larger.

I thought the SD was part of a enlarged 460 varient, but not quite the same.

Either way I would love to see what they could do on a dyno.

The 534 predates the 460 by 10 years.

Here's some dyno info:

Ford Super Duty engine - Wikipedia, the free encyclopedia

The turbo set up doubtless makes a lot of torque, but as far as other hot rod parts, there are none.

A 460 can be made into a much more powerful engine with easily available parts.

I would have loved to have one of those engines as well. It would have been interesting to see how early the turbo boost came on and sizing. After all these were 3400 rpm max engines.

At around 7.2 to 1 compression ratio, they should have tolerated 7psi without much stress, although premium fuel I am sure would have been required.

BTW - they share nothing with the 460's other than the Ford name. You could even debate the blue oval nameplate as the trucks they were origionaly designed for and installed in did not use the blue oval emblem!

I was sorry to read that nobody wanted them and that they went to scrap. What a pity.

+1 !!!

As produced by Ford, these are slow slog all day without destroying themselves engines. Low rpm, low compression, low specific output, just hammer down and grunt along.... without melting a piston or detonating to death

Which is why it would be interesting to take a look at the turbo'd version and see what changes might have been made in addition to the turbos and assorted plumbing. Along with the expected RPM ranges, and the expected operational hours per year, and the expected operational hour limits between majors. (much like the heavy, medium and light/pleasure duty ratings in boats for diesels have different rated horsepower and hours of use per year)

Go back on the comments about the Sea Master. That was a draw-through set up, so your manifold, intercooler and the pipes are all full of pressurized air/fuel, just ready to send you into the next county should you drop a valve or have an ignition failure.

A smaller version of this:

Yah I agree, plus gas is hard on seals, and I would imagine the alcohol laced gas would have ruined the origional turbo seals by now. Viton seals would have had to be sourced!

Of course the reason why draw thru systems were popular way back when was it was easier witha carb, otherwise you would have to run a sealed air box, seal up the throttle cable and choke cable - etc. Then you wuld have to run some sort of regulator that would increase the fuel pressure inconjunction with the turbo boost as it built.

Easy to do now, but back then, we were still dealing with relativly unsophisticated mechanical fuel pumps and very basic electrics. Electronics were pretty much regulated to alternators, although in the time frame you were seeing some of the very first mass marketed electronic ignition systems, which were a bain at first, but with time they were made reliable, plus they went beyond "lab based" or "lab required" troubleshting tools and procedures and brought out everyday tools to use in the "field"
