Ok, just got my engine from the machine shop, 69 429 going in my 77.5 f250 4x4 blah blah etc.

anyways, i had them put on a edelbrock performer intake as it was originally a 2 bbl. i was just looking at it and on the front right below the thermostate housing there are 2 5/8's holes, one is threaded and one is not. the one that is not is the one that joins that 3 inch piece of heater hose from the intake to the water pump. is this for a press fit barbed fitting or is it a casting flaw?
i havent worked on a 429/460 before this.


-gbm-

 

I answered this in the 73-79 forums but both of my 429-460 edelbrock performer intakes came with a pipe in the box that is supposed to be pressed in. I put threads in the intake and put in a threaded fitting.
