im looking for a stock carb for my 72 with a 402. one of the members close to me has one for a 72 350. anyone know the difference for stock cfm in these two models? has anyone ran a 350 carb on a 402? all im looking to do is have an easy bolt on situation....thanks for any info.

I think the BB primary jets and secondary rods were the only difference.
