The 3TC is a classic Old School motor, which looks like a 1950s Mopar cylinder head. The T Series been falling out of favor with the aftermarket of late, they're dirt cheap in salvage yards. The design is overbuilt as were all the older Toyota motors - it's not thin wall. The head would make a good pattern for a Slant Six casting, a few T sixes have been welded up.

The 3TC is only 1.8 litre, but can be punched out alot more. 200 HP is well within reach of a streetable T series. CNC aftermarket T series heads were available but I don't know of any that are still around. These didn't get great fuel economy, but 20 MPG was good back then. It is a double rocker pushrod Hemi with Mopar inspiration, no doubt about that. There was also a OHC T head in foreign markets, the pushrod is on the passenger side. It would work better with the 170, nobody will care that it is Japanese. The all alloy V8 versions are rare in the USA.

Would that have been the engine that was found in a circa 1980 Corolla? Those really, really, *really* $#!+ - box Corollas, many of which were appropriately painted brown? What memories- a friend's mom had one of those when we were in HS. I remember a bunch of us taking it from Austin to San Antonio, and we were all wishing we'd borrowed her Olds Diesel station wagon instead because it was peppier than the Corolla and didn't smell as much like cheap plastic inside :-p No kidding. How Toyota's reputation went from junkers like that to "the best cars on the planet" is amazing to me. But the engines sure must have been tough, I still see one of those things crawling around from time to time, car literally falling to bits all around the engine, but rarely ever belching smoke.

Hmm........I'll bet this is more feasable than a whole new head.
Although it would still be "too much" for the average Joe, Maybe more folks/racers should look into this. (Just an Idea)

O.K....This thread is at the top of my list right now.
What exactly am I looking at right now, in this last pic?
It says a 241 Dodge....a V-8 Hemi head? Did you cut 2 heads apart to make this? Is this a real, "runnable" head, or just a mock-up for kicks?
Please explain; my ears..err..eyes are open!

I'm just floored by these head pics. What is that latest thing, some sort of 1950s Hemi heads cut and welded?

The original head is off a Red Ram 241"hemi.

Looks like somebody took two heads ....cut off 1 cyl each and "rewelded" them together.....either with stainless rod or Photopaint.

not as easy as the bolt on Supra head.....

I was waiting for that pic to turn up.

The one minor flaw in the Hemi and 3TC heads is the valvetrain. No way to run one side or the other.

Can I also toss in the existence of 2 Keith Black prototype Slant Hemi heads?

I missed that whole joke (before my time), but I've seen it mentioned enough to have expected it also.



I have to believe that the Hemi head is a spoof, but I was under the impression that the 3TC head might work. Both the /6 and 3TC are pushrod inline motors, and as long as the cam was on the same side in both cases, why wouldn't the 3TC valvetrain work?

I'll take a stab at that. Like the 241 Hemi, the valves are not inline on the same side of the head. There is no way to set up the linkage to operate the valves on the far side. That's not obvious from the picture because the valve cover is in place. Now, an overhead cam setup might be made to work, but not easily.

Growing older is unavoidable but growing up is strictly optional.

Let me ask again, how did the 3TC valvetrain work stock? If the cam is in the same location (or similar), then what's the difference? It functioned once as a pushrod hemi, why would it function different on the slant block?

Now, I will admit that I have tried to visualize the workings of the 3TC valvetrain and have failed, but my problem isn't the far side valve, it's the near one. The far valve can be opened with a long rocker arm.

Need to find a picture of the 3TC valvetrain....

Maybe this will help







Looks like the cam in the 3TC block is closer to the head than it is be on a slant 6. Might be difficult to get the pushrods over far enough to work.

The 241 heads are not welded, just butted together. They're really not a good fit because of the bore spacing. The 3TC is welded. Neither head is operational yet. Just "toying" around with ideas. If the pushrod angles could be worked out it would take a special cam because of valve arrangement. EI,EI,EI,EI,EI,EI.
It's easier to visualize with a cutaway pic.

OK, i was running through some old threads and this showed up.
Zilla, KB prototype hemi heads?

That was a rumor at one time Stan. With the recent events concerning KB I have no clue if you could even get information any more.
