Guys, I have a complete top end from a 1983 Turbo Regal. I have read that the 83 turbo housing is bigger/better than my stock 1979 one. Not sure if the housing means the aluminum part or the cast iron part though. Will the 83 housing bolt onto my 79 turbo? The 83 turbo is seized from outside exposure. The hood was off car for about a year. My 79 turbo is in good usable shape. That's why I thought about changing the housing. I can have the 83 turbo rebuilt if nothing interchanges though
