Centre main cap for big crank in T block using dowel sleeves

Divided intake manifold for T block

"C" crank cut down to standard A size in a T block. Also cam for use with the divided runner intake

A crank modified using my shrink fit flywheel hub in a T block

On left my new Sherman head with a LOT higher compression (8-1?). On the right a older version.

Showing a Fordson valve sitting in the stock exhaust. This might be a engine to try a reverse flow on!

Same engine showing conversion for Borg Warner T35 automatic

Crower crank in same engine

and finally another engine with a 4 speed (Ford). This has a drilled T crank

WOW! Les, I'm in awe (I second guess myself after changing the oil.....

I was hoping for a few smiles for people!! I don't recommend these things to anyone (unless they are also crazy)!!

I really like the modified intake port, very well done.
I think that is the way to go to get more performance.

I have run a engine identical to this. It works well with enough cam shaft. The divider extends all the way back to the carb.

Nothing impossiple, a 'T' WITH an od. AUTOMATIC
can be done----but why I like it the way it is..

Here are a couple of reasons;
1. I can! and enjoy the engineering challenge.
2. My wife wants a "T" speedster and can drive a standard just fine. 3. Lots of people struggle to get good with a T transmission
4. I found the automatic from a '68 Cortina at the local "help yourself " auto wrecker.
5. Having had a few close calls with idiots driving modern cars pulling in front and slamming on their brakes, I developed front wheel brakes for my T's
6. But really #1 is the best reason. It keeps life interesting for me.

Please forgive my lack of engineering knowledge, but...since Sipes and others are manufacturing CNC machined counterbalanced crankshafts, would it be difficult to make one in a 2 up/2 down configuration, or even rotate the front and rear halves 90 degrees as was suggested in another thread? I would think that CNC machining of a camshaft to fit such an engine would also be relatively easy by just changing the computer program.

Awhile back I looked at putting a flathead V8 crank in a T block (I have a spare one sitting here). It actually fits pretty nice. One problem is you will get a uneven firing order (it would sound kind of like a Harley or a John Deere tractor). And maybe that would be cool.
2 up 2 down crank. No problem buying one from Crower for about $2,500.00 for a few off. The cam is probably $500.00, although to take full advantage it should be engineered a bit.

So with reverse breathing all you need is a new cam (to take full advantage of it) and a chain drive for the cam that the parts are quite cheap for.
Anyway you spend your money however you wish, and I will spend mine how I wish

Explain why you need a chain for the cam. Why can you not just change the lobes and use the original drive gear?

Like Noel, I am not an engineer. I deal with drugs.

If you are going create a camshaft from scratch you are absolutely right. The reverse rotation allows you to use a camshaft that already exists. There are some pretty "wicked" camshafts floating around out there, and reverse rotation allows there use to be optimized.
Interesting to find a "drug dealer" on here, but nothing much surprises me anymore!!
