Well I changed computers and forgot my password, waiting to get it reset.
Here is what I have, found a 65 C60 wrecker truck.
Block casting 3914660 pad #'s T0508HH 18S238434
Pass head Hump 3890462 GM1 B186
driver head Right angle 3947040 GM4 C27 8
I found the head applications but can't figure what the block was in. Found it to match a 327 Vette but, surely not! Not in an old rusted down wrecker truck.
