502BB into 78, how?ch. mounts?

[alspeedy]

im attempting to install a 502 into a 78 camaro, with 2" hooker supercomp headers and im using the stock 78 motor and frame mounts. will this work or not. so far headers wont fit. do i need mounts from a 70-72? if so how are they oriented. spin frame side mount so single hole is on top or just place new mounts back in origional factory spot? please help the 2 hairs left on my head are in danger of falling out, or being ripped out!....thanks john
