Do all 200-4R's have the BPO bolt pattern on the bellhousing? I've been looking for one locally, to stash back for my wife's 77 Trans Am. Not having much luck finding one, but just kinda half hearted looking at the moment.
Yes. I believe all 200-4R's are dual bolt pattern. We had one built for a customer's '69 Firebird convertible behind his 472 stroker. Finding cores is tough.
