It's coming from the spot where the water pump connects to the intake coolant crossover. Just speculating, but I've seen where some folks actually cut the coolant crossover from the intake manifold and I think they do that so it'll fit tighter in this location.

Good eye, its the intake

Hello all and thanks for letting me join up. I finally found my 1963 Tempest recently and traveled all the way to California to get it and bring it back to Georgia. The car is in exceptional condition, leaving me to believe it spent its entire life in California. I've sent in to PHS to have the car documented as to where it was invoiced and its production particulars. The car is far from stock as it's been modified to replicate one of the 6 Super Duty Coupes. It has a 400 with the dual 4 BBL induction and TH-350 trans with a 9" rearend with the typical race inspired ladder bar/coil over arrangement. The car is a street car and I will keep it that way. I'm fairly new to Pontiac engines, but have a good back ground in high performance big block chevies. So I'll be leaning on you folks to help guide me thru this endeavor. I would welcome anyone in the local vicinity to reach out and possibly meet up to share some good ol bench racing. Thanks again, Rob
