Ford 428 Police Interceptor Intake Manifold. Surface just restored by Houston Vapor Blasting, looks new. Factory milling marks on all surfaces, so never cut, and ports have never been touched. One weld repair on bottom (see photos), likely for porosity and there is a crack on the bolt hole for the distributor hold down that one might consider repairing with a helicoil or similar threaded insert. Otherwise one of the nicest original 428 PI intakes that I’ve seen.  SOLD

Thanks,

If I understand the Holley info correctly, and hopefully I do since I'm dealing with a similar situation, the Sniper will output a (-) ground signal to activate your fans.  On my car, and what I think is a typical setup, the temperature switch is between the chassis ground and (-) post of the fan relay.  Once the temperature reaches setpoint, the switch closes and gives the ground path to the relay. The Sniper has two wires you can use, the blue & light green, either of which can be used to give the same ground path to the relay.  I think there is a YouTube video that shows how to test it by lowering the temperature setpoint below ambient in the Sniper controller to see if the fan starts.  All that said, I'm no expert either, but I think that is all there is to it.

My D4TE block has the compressor drain hole on the passenger side skirt, but has the 'automotive' size hole for the bottom of the distributor.  I was expecting to need a bushing, so I was surprised by this.

Looking for a nice set of 65-68 alternator brackets, the upper support bracket and adjusting strap. Let me know what you have.

Thanks,

Y-block 2 - 4 intake from a '57 E-Bird.

FERoadster sent some CJ valve covers to test. Here’s the results after a few minutes in the cabinet.

Here's a look at a few of the parts that I've done, simply vapor blasted, no coating of any kind.
