Answer85s came standard with: Buick v6-231 2bbl, buick v6-231 sfi (w/turbo), olds v6-263 diesel

however most rear wheel GM engines should fit depending on how much customization you want to do. i recomend a 1970 buick 455

you can also drop in an olds 307. Its a well rounded engine and can be beefed up some too.

The 85 buick Regal Limited came equip. with 305cid small block chev engine. this is to say any sbc combo will fit as well as bbc (use short fact,style valve covers to clear heater box if bbc option is used) My best advice is stick to the sbc chev very cheap power ie 383 stroker ect. find a early 80s chev montie as a doner car for all nessary bits ie throttle linkage mounts ect Very easy swap no mods required
