Turbo 350 vs. Metric 200 (stock eliminator)

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.

[Jesse Knapp]

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.

Is the reciprocating mass less in a 200 than a 350? Has anyone ever used a 200 in a heavy big block car. When I say heavy I'm talking 4200lbs? Or won't the 200 withstand that type of weight. I have been thinking about that and was just wondering.

[Bill Edgeworth]

They are considerably lighter. The 26# I quoted earlier in the thread I think includes the weight of the case. So the exact difference I don’t know. It also depends on how you have them built McClay can build them with aluminum drums if you want to cough up considerably more money. However in a stocker he told me at best it’s only worth a couple hundredths as the 200 drums are already fairly light.
As for whether a 200 will hold up in your application I couldn’t say but they are being used behind Super Stock and Comp motors but I’m fairly sure in those applications they are seeing far more maintenance than would be expected in a stocker. Probably the biggest question is if the input shaft can take the torque of the big block. As Todd Hoven mentioned the input shaft conversion is a real good idea if you are going to run it behind a big block. And which big block will make a big difference in longevity also there is an awful big difference in torque between lets say a 402 and a LS6.
