GM bolt sizes
So i'm putting the motor in this weekend and wanting to replace a lot of missing/damaged bolts but don't know the correct sizes. bolts such as water pump to block, bellhousing, crossmember thru engine mount.....i'd like to just go to a local bolt/screw dealer to buy them all but all I know is that they are grade 8. Does anyone know of a good resource that can tell me bolt size and thread count for GM bolts?
FWIW it's a 79 GMC 454 going into a 1969 Camaro with a TH400 and i've got all the right big block mounts on the frame and engine.
Thanks all,
RobertRobert F.
