Actually I've had the blower since 1988. I bought the whole system from Dick Landy (DLI). B&M (as usual) ignored Chrysler when they built the blower system. Dick Landy did all of the dyno work for B&M so he decided that if B&M wouldn't make it then he would. He took a Offenhauser dual quad mainfold, cut the carb flanges off and mig welded the supercharger flange on. The disadvantage to his system is that the manifold is not a low profile design so it doesn't fit under the hood (hense the six pack hood). The advantage to his system is that he used the big block 174 blower for the small block Mopar.
