Holley 3810 question

[Chuck M.]

We are in the process of having our 3810 (L79 motor) restored and I have a question about the screws that hold the throttle plates on the shaft. What types of screws are they and what should they look like? Thanks for the help!

Re: Holley 3810 question

Very short, I think a #6 machine thread slotted truss head brass screw that is peen to insure it stays put.
Length is just long enough to protrude thru shaft to allow peen spread of thread.

I have seen some with a slotted shallow filister head but I don't know if they are original.
