    question as a newbie here and hope i have the right forum....1972 GS w/350 and has A/C

    I know i need a BB fan shroud, will the 350 clutch fan, A/C pulley, alternator pulley and all brackets fit etc....???
    Will BB Chevelle front springs work in the Buick?

    any help would be appreciated

    Fan and clutch will work although depending on which shroud you get, you might be better off with a larger fan. The 71-2 BBB fan shroud has a larger opening than the 70 BBB shroud. Alternator and A/C should tranfer over, not sure about the P/S, but I believe the 72 P/S is the same brackets.

    A BBC is 130 lbs more than the BBB, more if you use the aluminum intake/heads.
