[Zeke Topanaga]

Most use chev 400 rods with the old holden crank offset grind to make 286ci with 0.030 over bore.

Only reason I posted was to see if anybody has actually done it, because I know the cams are the same

not strictly correct...they look the same but
factory 253 and 308 cams are different.. plus they are also timed/set differently via different chain gears
