Yes, I know 18 is their smallest.

There is a 10 and 14 available on the net, we made a 12.

Trust me, the good doctor ain't milling custom distributor bushings....

OK, thanx for the info about the intake leak, which was immediately obvious after hard driving at the right rear "China" corner, but using a UV light + dye revealed oil leaking from the front, esp on the driver's side and from the rear not only in right corner, but across the middle. I'm just disgusted as I was very careful in trying to do this job. Does anyone ever use the cork gaskets they always supply for the ends? I never have, but jeez...

Timing: I have an MSD box (6 AL, I believe), a standard Ford FE distributor with the advance locked out and an MSD programmable timing computer (8981) now superseded by a the model 8680. s

I wish I had a "magic bullet" for intake installations to keep them from leaking but, alas, I do not. If you just can't, can't, can't get it installed without it leaking, and it didn't leak before you removed it, then I would start to suspect something is warped or cracked or the like.

Well it's time to check in with ol' doc Steve and see if he's making any progress on the Kirkham now that summer time is right around the corner....

If you were topping a 460 with an Edelbrock Torker II I could help: the manifold was made incorrectly in the area around the distributor at the front.

Incorrectly means that the manifold did not overlap the china wall, so a bead of sealant had nothing to adhere to. The manifold was cast with its flange about 1/8" to the rear of where it should have been. Leak, leak, leak...

The fix was to form a 1/8" wide piece of aluminum and adhere it to the front of the manifold with some diesel sealant. After that cured, installation was successful and no more leaks.

Takeaway: dry check the manifold's fore-aft position and assure the ledge on the manifold actually sits directly above the china wall, and not behind it, so as to contain the sealant bead effectively.

Oh, and Edelbrock says "their manifold is not at fault," of course.
