Turbo 350 vs. Metric 200 (stock eliminator)

[Jesse Knapp]

Which one is faster behind a smallblock combo? Heard the stories that the 350 can be as fast if it's high dollar stuff. I also heard the 350 is more durable. I've raced 350's and glides but never a 200. So, if one does a Rossler or another high end piece, will the 200 go faster (quicker)? My concern is not as much about durability. I care more about elapsed time. Are there any problems with a 200 fitting a (68 to 72) Nova? The stick idea is very appealing to me, but my lack of knowledge in the clutch area makes me lean towards the automatic again. Thanks for any replies.

The 200 fits where the 350 fits, same drive shaft, mount, and cross member, the 200 is actually smaller. Most say the 200 is faster in a small block car. If I were going to a 200, I'd get a McClay, and I'd get the pump modified so a regular turbo converter fit.

I remember Keith Lynch saying the 200 was quicker than his 350 both quality pieces (so he said)!

I think Rossler does the 200 also. He should be able to give you a good idea

Wish I had the xtra money to buy a good 200 to find out for myself

Thanks Alan. If it's a bit smaller, then is it lighter as well? Also, with the deep aluminum pan, is the oil capacity the same as the 350?

Yes ,it is a bit lighter to start.
There are two different factory fans. The deep one holds about one more qt.
Leo (Remac) sells a fabricated aluminum pan.

Yes, a 200 is slightly lighter than a 350, even if the 350 has both aluminum drums, and the 250C shell and gear train.

Given the same depth pan, a 200 holds less fluid than a 350.

McClay is the only way to go.
I think Scott told me its 26 pounds lighter than a 350. The pump conversion is a good idea I had him do it to my 200. Also the auto 1-2 is a good option to get for consistency. It’s real easy to adjust and it’s an external adjustment. The case brace and needle bearing output shaft are also a good idea. My McClay is considerably faster than my 350 with about the same low gear.
I put over 400 runs in a 3600# car on it before sending it back for freshening and he said it was in great shape. So properly built they are quite durable.

One more thing I should add and maybe someone like Mark Yacavone who knows vastly more than I ever will about 200’s could comment on this:
You need to let your converter builder know it’s going in front of a 200 with a 350 pump conversion.
Something to do with direction of oil flow and excessive pressure build up in the converter. I heard this from Coan.

Thanks Bill, It most likely has to do with using the support bushing ,either inside the pilot, or in the stator support. I don't build 350 conversion transmissions. I just build straight 200 converters to go with my trans's.
My new 305 converter will be for straight 200s, at first,which I think will be the most popular.
Again, Leo also builds the 350 conversions ,as does Jack Sepanik and a few others.
