Below are some pictures that xtaxi asked me to take as a matter of referance. Rather than just PM him the pictures, I thought I'd share them with anyone that may want them for referance.

All pictures are from a 1989 HSO engine.

Teaser for xtaxi
Also, in this picture, each end of the head is featured. What could the round indentation on the non tstat end be for? Freeze plug?

One side of the rockers

Other side of the rockers

#1 Intake & Exhaust
Intake is "D" shaped

Front of the head with spark plug holes

Same as above

Would anybody mind to tell me if these valves look normal for 150K? The exhaust manifold was completely cracked into 2 peices and wouldn't idle without some help from the gas before I started parting it out.

Lower intake

Intake mounting flange

Injector bungs on the lower intake

If you have any requests for pictures of specific parts or specific angles, feel free to drop me a line and I'll see what I can do.

: Aren't the HSC 4 bangers loosely based on the 200 six?

Sorta... "Freeze Plug" is a misnomer. Correct terminology is "Core Plug." It's a necessary part of the process of casting hollow shapes out of metal.

Yup, the share the same cylinder bore and afew other features. That's what brought me to this site originally. The chance of learning afew tricks that might allow me to hop up my 4 bangers.

But if you consider it, there is a linage from some of your Fairmont/Zepher's and the Tempo & Taurus. They all had similar engine's and shared roughly the same spot in ford's lineup.

Is the "plug" removable, if so what would be found behind it?

It is just a plug for a casting core.

The HSC engines share the same bore spacing and bore. The layout is similar. The head bolt pattern is the same. So is the rod bearing size and rod width. But very little actually interchanges.

Too bad the head isn't alloy. Those fast burn chambers are a big improvement over the log and a welded up head would be neat. If you had a good and patient welder, you might be able to add the two end cylinders and cobble up some manifolds.

It is, and behind it you would find empty space (the water jacket). When the head was originally cast, there would have been sand there, epoxied/molded into the shape of the water jacket, and later removed. Same deal with your block.

Ah,Tim old man! I see you have that doller you owe me ........................I take money orders & or a check ! He. He. He. OO6./The-X-Or-Six!

Tim, that was fantastic. My compliments!

The 2.3/2.5 HSC engines are quite different to a cut-down 200 head. The rocker cover encapsulates all the head bolts, not just half of them.

The ports are H-U-G-E, and exhast ports are very big and round!

The head is rather similar to the cast iron cross-flow, with a very heafty bulkhead holding the intake ports.

The HSC split line is faced away from the exhast ports, any oil leaks gravitate to the plug side of the head away from the exhast, just like the 200 and the X-flow.

The details on the rocker gear are Cleveland, 90 degree Essex V6.

Lower intake is very much like the Nissan L-series.

The leading battery terminal on the 200 is exposed, not so on the HSC.

There are lots of advances there!

I was talking many moons ago to Mark P, talking about duplicating the HSC head in cast iron for the I6. It's quite involved, but it may be possible if you mount a HiPort coversion plate on the intake/exhast side.

A lot of work, but those ports are monsters!

I'm also intrigued by the intake manifold. It looks like the runners are all independent, and just held together by a relatively small web of aluminum. With a hacksaw and some patience, they could become pre-fabbed runners for an MPFI set-up on an Oz head. Just make a mounting flange for the motor side, and attach them all to a plenum and you could be in business. Assuming, of course, that the intake runner diameter is close between the two.

Anyone have runner diameter numbers on the HSC intake manifold?

Well done, Tim! We are all gear heads here and I for one always enjoy reading about and seeing pics of different engines.

Maybe we should move this thread to Hardcore Tech, as it really isn't about the small-block I-6's, yet it is interesting and relevant.

I'm with Stan on that one. It's nice to see the inner workings of an inline other than a I-6. The only PROBLEM we all have now is,that Excute is going want one of 'em to play with 8) . Like Stan said,we are all gearheads. Hmmmmmmmm. Why is it that INLINERS are the only open minded 'car-guy's?' V8 guy's are just that(on the whole that is......)V8 guy's . OO6./The-X-Or-Six!
