Coolant leak

Coolant leak
Recently had 350 professionally rocket rebuilt. Have finally got it installed and running, however we are seeing coolant leak from the back side of the engine. Any ideas where it could be coming from?

Take it back to the "pro", have them figure it out for you! Could be a lot of things- cracked head, block, bad gasket- intake ( my guess), head etc. Is it coming out from the back of the block where it mates to the torque converter ie: water dripping out of the torque converter dust cover or do you see water running down the "outside" of the block?

Coolant Leak
Thanks for the responses. The leak is originating under the bell housing. Spoke to the rebuilder. He says that sometimes the coolant will trickle by the new freeze plug(s) which is silver. However, once the engine comes up to normal operating temp the plug, 99% of the time, will seal itself. There are 2 freeze plugs on the back side. Once were fully operational we'll run it awhile and see what happens.

I think he's trying to mug you off. Freeze plugs shouldn't leak if properly installed. Period.
Otherwise when we go to the garage and see a puddle of coolant under the car we would just say; "Hmm... cooling system seems fine, no oil leak though, better take it to the shop and see why not."
If his freeze plug installation is anything to go by I wouldn't have much faith in the rest of the engine..
