BUICK RACER Posted December 4, 2008 Share Posted December 4, 2008 Yes, it will fit, no problem, but you will have to change the motor mounts on the frame,depending on if you keep the probably existing 350 hydramatic transmission, you may have to move the crossmember and shorten the driveshaft, should check out V8buick forum Link to comment Share on other sites More sharing options...
