Keith Black KB845 - http://store.summitracing.com/partdetail.asp?part=UEM%2DKB845%2D030&autoview=sku TRW WL2329F30 - http://store.summitracing.com/partdetail.asp?part=TRW%2DWL2329F30&autoview=sku Main differences arethe ring size. KB is 1/16 and TRW is 5/64. Both will give me almost 12:1 CR. No much infot for the TRW. 1973 Brasilian Dart E100, boosted 390"

The TRW is a flat top with four valve reliefs, not a dome high compression piston according to the information on Summits site you attached to I thank it is a stock replacement forged Speed Pro piston wit a compression ratio of around 8.5 to 1, maybe not The KB is a domed psiton so it should have the higher compression your looking for Mr.Cab Racing and winning with Mopars since 1964.
