im wondering if there is a difference between the f22b2 block and the f22b1 i got a f22b2 now and i want a spare to build well pretty much just a block and i found an f22b1 for cheap wondering if i could build the f22b1 block and use my head and be fine thanks

 

I know the f22b1 has a main stud girdle. B1 block has a windage tray also the b2 does not. Thats just one things among others.

 

Aren't the crank gear and water pump different as well? 1 more or 1 less tooth IIRC. Other than that the block design is pretty much the same. OBD1 & OBD2 have there differences but the blocks them selves don't change. Just the parts that are bolted to them.
