Hello Great forum. I am helping out my brother and nephew. We are working on a 1990 Chevy Caprice Police Package 9C1. Has anyone put a 500 in one of these ? We have 2 motors and 3 TH400 transmissions. What kind of motor mounts are required ? Any help would be great. Thanks Kelly

If that chevy is the same as the 77-96 full size RWD caddy, I think it is. you can get all your parts off a 77-79 deville or broughm...oil pan,mounts and many other parts ... y pipe if you run single exhust.. almost any other part will fit... Good Luck

Did you get you swap done? What did you use for motor mounts?

I think that front crossmember/frame section is same from 78?? -forward to the last rear drive Cad -96 Caprice/Impala -Roadmaster. The engine mounts -brackets from a 77-79 deville -fleetwood would be a direct bolt up. Also whatever years used the 368 -4/6/8 engine 80 and maybe 81??
