Sfi 200 metric case
 
I was looking to see how much interest there would be in an SFI approved TH 200 Metric case.
I would think with all the people using them in stock & super stock, a corporation that builds this type of case would stand to make a nice profit given the new 10.99 rules?

Would you buy one if it was available, instead of using a blanket or shield?

I'd take one!!

I see ATI just released a SFI case for a 350THM . They may be a good place to ask, if there is enough interest in the 200 .

The 350 case will not be available until end of season.

While there is not an SFI case for the T-200, if you want a stronger case, if you can find one, use the BOP T-200-4 case that was used on GM cars that were powered with the Oldsmobile 350 Diesel engine.

The bellhousing and case is way stronger and even heavier because the additional material in the case.

The point of the SFI case is not only because it’s stronger, it is so you don’t have to purchase a blanket or shield. A different production case doesn’t solve this issue

Correct, however, there has been an issue with cases cracking and the reason why they sell braces to prevent the cracking.

Joe, Did they make a 3 speed diesel case?

Yes they did. GM cars, including Cadillac that were powered with the Olds 260 and 350 Diesel engines, depending on the year, had either the THM-200, THM-200C or THM-200-4R transmission. All the cases were BOP and beefier.

However, the first year the engine was introduced, 1978, the transmission was a T-250.

I learned about it from a former colleague of mine, that was a drivetrain/transmission engineer at GM. On the side, he rebuilt transmissions at home. He heard me talking on the phone with another racer about the T-200 trans and he asked me if I needed a stock transmission. Also gave me a dissertation of all the GM transmissions and told me he had a BOP T-200C and he rebuilt and didn't have a use for it.

He shared the transmission had a beefier case for the diesel application. When I picked it up, he was not kidding. The bellhousing and case were beefier and did not look like the case of a T-200 I had purchased from TurboAction.

ON A SIDE NOTE:
The 350 case from ATI looks like it is a Chevrolet pattern only?
That is just dumb.

Besides that, the TH 350 in drag racing is not all that popular any more, in cars that would need an SFI case.because of the new rule.

As well,
IF,...AND THAT IS A BIG IF!!!
Someone was to make a TH 200 Metric SFI case.
In my opinion the corporation should consult with the likes of Scott McClay, and Leo Glasbrenner.
In an attempt to have things set up in the case so they will work with no modifications.
And a dual pattern bell housing to fit Chevrolet and B.O.P. would also be a necessity.

Glen,
It's still would have to be mucho expensive, the way I see it. It's still just a tiny niche market.
