Can I Transfer the B18A1 internals to B20B4 block?
I have a spare B18A1 complete shortblock and a bare B20B4 block with main caps
I've heard that all the internals are same except the bore size only...
In order to make things sure, I would like to know if I can re-use the followings B18A1 parts on my B20B4 block??
oil pan
pick up
screen
windage tray
crank pulley
right side cover
crank
of course bearings, thrustwasher, rods, rod bolts, and pistons are going to be changed...
