Head casting # 3932441

Number of front engine pad 919Z362121 TO625HD
Please and Thank you.
Could you tell me what his could be out of and how much stock HP it might be pushing?

Tiger -
What you have is a bit of a mystery, but this may help:

3956618 casting was used in 1969 302 engines listed as 290 horsepower, 4 bolt from a Z28. If this is truly what you have it's a gem. However, this casting number is inconsistent with the number stamped on the pad, i.e., the TO625 indicates the engine was made in Tonawanda(T) June(06) 25(25)th.
"HD" is 1965-66 327 and 1969 350

This casting number is also used for:

1969 327 listed as 235 horsepower, 2 bolt main in full size (Impala, Biscayne) and 1969 350 listed as 250 to 350 (depending on how equipped) with either 2 or 4 bolt mains. My guess is that you have a 1969 350. If it's a four bolt, it's a great block to build. If it's a two bolt main - it's like a gizillion other 350s out there.

3932441 are 1969-72 heads with small (1.9, 1.5) valves. If these are the original heads, you probably have a fairly common 250 horse 350.

Others may have more information..

I to believe that its a 69 350 it is a 2 bolt. I was just making sure. The plan was to get rid of it. Thank you
