Your exhaust front pipe might need extending to get the system to line up properly.

Water pump pulley bolts need cutting/grinding to about half their original depth.

You doing well. I would consider having the block decked if you haven't built it all up properly yet, I recently killed mine and its looking like it could be down to me not having the block decked.

Wideband I would suggest put it in the front pipe inbetween the bulkhead and driveshaft pointing straight upwards.

Your doing well, I will get the pic of the sump where I cut mine asap.
