yes gotta search by vehicle that came with bbc. If you use year 1980 C30 and select engine, it should give you a menu to pick from. Then pick your area, I use Southwest as it covers Oklahoma, then pick $$. Once you hit search it will also show other years related to a 454. You have to search the GMT 400 trucks (1988-1999) separately. You need to narrow down which version BBC you want MK 4,5,6. For me either 4 or 6 as the MKV has some quirks to it. I didn't see where in the US you live so I can't help search.
