Turbo 350 vs. Metric 200 (stock eliminator)

[Bill Edgeworth]

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.

Thanks for all the info and help last weekend.I found the valve body was the problem.Talked to Billy Lynn and he told me what to do.Did not get to go to Dallas.But will be ready for PineValley

Get the turbo input conversion if you are going to get a 200. The stator tube is suspect. I broke one bad at Cecil County after I spun the tires hard and it took out my good converter and turned it into junk. If you are going to buy a 200, Leo Glassbrener is the guy to use. Great giuy to deal with, and you don't have to wait long. I broke mine the Saturday before Indy, and he had one to me at my trailer Tuesday morning. I put it in right away and 2 days later won G/SA Class in a very tough field. If it wasn't for Leo and the guys at Remac I would have never have been at Indy. I have since put 60+ runs on it and never had an issue. And this is in a 3700 pound car that has run in the 10's quite a few times.

Thanks for all the info. Sounds like some people race the 200 behind a bigblock. I would think it wouldn't go too many passes. Too bad I sold all the 396 blocks I had a few yrs.ago. My friend Kenny, he has a tranny shop, has built every tranny I've ever raced, including the glide for my superstock car. The glide had everything possible in it (ATI) and held up quite well with a brake. Kenny advised me then to go with the turbo spline for it. He uses some of Rossler's stuff, and that's why I mentioned the Rossler name. Guess I need to look for a 200 since I only have a 350 to build.

Jesse, you do not need any 396 blocks. You build a 396 for stock by pouring a production 454 block and sleeving it down to the 396 bore size. The only "old" stock piece you MUST have is a crankshaft.

Alan. A machinist friend told me that awhile back. The appealing part is the thick cylinder walls you get. I bet it's costly, though. I even checked my GM catalog and there is no bowtie replacement. My thing is that I sold a mint block ready to build and three spares, with the crank, heads, and gave the intake to a friend that runs a Nova stocker. I think I am going to do the 69 yr. with a 350/300-290. I have a bunch of 041 heads, 4 bolt blocks, intakes and cranks, steel or cast. Build it light as possible and run E. I don't know that anyone does that yet with a Nova. It is really nice to have all that room under the hood lol. I am a pack rat, except for the 396 stuff, for some reason. I appreciate your help and enjoy the talk.
