520 heads on 327 /250's was 64 and earlier.
65 327...Same exact specs except for carb.
My question has to do with how much real dyno hp and whether the AFB is worth the hp to offset the weight.

I had a friend who bought a 65 Impala, 4 speed ,327/250 new, and it came with single exhaust .
I doubt you would have seen a 327/300 that way...Ancient history though.
