I have the chance to pick up 1990 Cadillac Coupe Deville with the 4.5 V8 front wheel drive. From what I can tell, this is a 273 c.i. aluminum block with cast iron heads. 1.811 throttle body and the engine is a 3.623 bore and a 3.307 stroke. is a 10.28 compression with a 7.9 cc dish piston and 45 cc head. 457/473 cam. From the classification it says that this engine can have external air inlet. I don't recall anyone running on os these back in the day, but has anyone on here tried. Rated at 180 hp or 16.70 weight break. would be a B/FS and can ballast to 17.5 to run "C". B is 14.65 and C is 15.15. Just curious if this is a dead horse or can it be made to run? Thanks guys.
