440 Small Bock!

hot rod tested it,they also mentioned that the heads are as cast ,unlike the chebby and ford entry. imagine what kind of power with a good port and polish.

If the heads are as cast they are leaving a lot of power off the table:

For the kind of money I am hearing for that engine those heads should be fully ported. Does that price include a new transmission and full exhaust?
