I have a block and am trying to get some information on it. The main thing I would like to know is what kind of power levels it can see. The casting number is #3932386. Any help would be great. Thanks!

Should be a 1969 4blt main block. As is I would think it would handle around 500hp with main studs. This is a better restoration block than a performance one. My boss buys this casting number blocks. If you are interested PM me the casting date and the suffix code that is stamped on the deck at the front Passenger side.

That block may have the 2482 center caps making for a good peice if the cylinders pass a sonic test. that should be a good 500 horse piece.
