Mikelly Posted February 19, 2003 Share Posted February 19, 2003 Guys, I need to get a flywheel sent out to my builder. Looking for a 153 tooth internal balance SBC flywheel (Preferably SFI rated). Cheaper is better... Mike Quote Link to comment Share on other sites More sharing options...
Mike C Posted February 19, 2003 Share Posted February 19, 2003 Check CAT http://www.catpep.com/ They used to have their price list up, but I couldn't find it last week. For example, they have their SFI certifiedl steel balancer listed for under $100 last month. Great prices, at least they were... Their stuff was in one issue of the Summit catalog last year, then disappeared. Don't know what was up with that, but I've seen mentions other on the 'net or in magazines with buildups using their parts. Quote Link to comment Share on other sites More sharing options...
jt1 Posted February 20, 2003 Share Posted February 20, 2003 I know Ram makes an aluminum one, and probably a steel one. Quote Link to comment Share on other sites More sharing options...
Mikelly Posted February 20, 2003 Author Share Posted February 20, 2003 Thanks Mike C.! I'm in touch with CAT as we speak... I'll post when I find out what they have... They have two listed for $100 and $105, but I suspect they aren't for internal balance applications. We'll see! Mike Quote Link to comment Share on other sites More sharing options...
Louiem Posted February 20, 2003 Share Posted February 20, 2003 Somebody correct me if I'm wrong but aren't all chevy small blocks internally balanced except for the 400. I pulled my from a 305 camaro together with the 5 speed. It bolted right up to my 350. It's a work in progress so I don't know how it's going to work. It did come with the 10.4 inch clutch. Louie.

Mikelly Posted February 21, 2003 Author Share Posted February 21, 2003 Nope, not all were INTERNALLY balanced, which is what I found when I started researching small block chevys the first time I built the 383. Mike Quote Link to comment Share on other sites More sharing options...
Mike C Posted February 21, 2003 Share Posted February 21, 2003 From GM, all SBC and BBC were internally balanced. Until the arrival of the 400 and 454, both in 1970. In 1986 when GM switched to the one piece rear main seal, they eliminated the counterweight from the back of the crank. This meant that they had to add a counterweight to the flywheel, so all SBC post '85 are MOSTLY internally balanced, save for a counterweighted flywheel. The 400 used a damper that was not zero balanced and so did the 454. Quote Link to comment Share on other sites More sharing options...
