5.7 swap dash questions.

I did this in my son's 73 Scamp. I was a little nervous about the core with Hemi operating at a little higher pressure. It's fine so far. There's a port on the driver's side of the block/birdhouse area. Points directly to the driver's side, use this for water temp. There's an 1/8 NPT port, facing front, behind alternator for oil pressure. The two wire plug on the back of the alternator can be spliced to the existing field wires for your factory amp gauge.
