This is going in a street/strip car. How streetable are aluminum mains? Also who's should I use? BCR's aren't available anymore. Thanks Jamey

My Belvdere went mid 10's with a pump gas 451 and logged over 4500 street miles when I sold it. It is still going strong six years later.

Thanks Jamey Your only option now is Best Machine Koffels or 440 source. Support the Moparts guys and buy from Best Machine for now. No problems running them on the street. Lots of my customers do at least 20% Greg www.bcrproducts.com

I haven't seen anything out of hinm lately. Anyone know what/how he's doing? 5741922-Blockal.mains.JPG (50 downloads) Last edited by Madness; 01/17/10 06:52 PM.
