Its a crate motor but also a service replacement, parts counter engine for normal service.

These engines are not rated by HP, they are meant to be generic replacements for engines gone bad and used in place of any 350 engine, car or truck.

MB19800 is a Targetmaster

M - Made in Mexico
B - Built in Feb
19 - Day of month
800 - 1979 model year service part (would have been built sometime from mid 1978 thru the end of 1979 model year engine production)
