im putting together a 82 sanger mini day v-drive. its currently at bullett fiberglass for some stringer replacement because i want it perfect. im building a mild big block .30 over 454 but i always wanted to go blown. im looking at blower kits and there are several kinds. i dont want the WEIND cause i dont care for the looks of it. im debating on THE BLOWER SHOP or a BDS. whats the diff in 1V or 2V hell whats that mean? whats the diff in marine vs non? with my set up should i go with a 671 or a 871 i noticed my books dont show BDS with a 671 for a bbc. can i get some input on what is the best way to go
