Picked up this block cheap (free) with heads (14102193) and bottom end included as well.

The block is 10054727, has the 5.7 L designation and says CANADA on it. The code is K1113FBC, the K being the Canada plant and the 1113 the date. I have searched multiple reference books and the web. My books don't even have the 10054727 casting number, though many tables around the web do. It happens to be a 2 bolt main. It is the 1 piece rear main seal but does not have a spider in the lifter valley.

Has anyone ever seen the FBC suffix? I am unable to locate it on any of the references i have searched. Anyone know what engine application this is from and what the horsepower was? The bottom end is complete but no intake.

I am planning a supercharged 383 build-up and am looking at this block and 2 others for the foundation. The others i have info on but this one not sure? Also any indication whether or not these heads are usefull would be appreciated.

The block has no provision for fuel pump and the date on the passenger side indicates November 1986.

Anyone know how many vehicles GM put the 5.7 L into in 1986 and 87? Camaros i guess it was only available in 1987 in limited numbers? November casting probably indicates an engine installed in a 1987 model year car?

Thanks in adavance!
