BJ, I have a copy of Rocky's version, upper left in Mikes picture - you are welcome to it.

Text me your address & I'll try to get it out to you in the next couple of days.

My HO intake is dated 2/22/71. The timing cover bolt hole is 1/4"-20 instead of 5/16"-18. Just curious if this has to be an incorrect repair or a factory mistake.

If you convert to US dollars that is only $3500 and it does have the correct carb . I don't think that is a bad deal.

Hi Bob,
You are correct about it should be 5/16" not 1/4". The proper bolt is 5/16-18 x 3 5/8 long.

If your intake has 1/4-20 thread it is one of the two things you mentioned.

02/22/71 was a Monday back in 1971.... Machinist may still have been suffering from the brown bottle flu Monday morning from the weekend. Hard to think it though. You sure it's not just a banged up starting thread on your intake? Or does a 1/4-20 work just fine. If so, I would get me a 6" long 5/16 bolt, cut it to 3 5/8 and have a machinist cut it down and put a 1/4-20 thread on the end of it. No body will ever detect it. Or install 5/16-18 helicoil in the intake. Guess which ones easier!

Good Luck

I removed the intake and was able to get a closer look at the 1/4"-20 tapped hole. Definitely signs of a helicoil...

I'm short one of the 4 studs that secure the intake to the heads. Cutting one of the currently available hex head studs to the same length as the OEM studs and then turning the threads down on a lathe should make a close duplicate.

That explains it. Somebody repaired it with a 1/4" helicoil instead of 5/16". I tried to send you a copy of all the stuff with the exact dimensions for the all the 455HO fasteners from Pontiac for this, but the format on the forum is different than mine and it all ran together, left it unintelligible. Good luck on sorting it out.

Pretty sure that a striped out 5/16 threaded hole would be to big to accept a 1/4 20 helicoil

Let's just say this project has had some "bumps". Ray of hope shining, despite losing a season. Unchained by non-correctness is fun. Cliff supplied cam, roller. Praying for a run before winter. We've had snow already. Be kind, "It's A Driver"

Thanks y'all. Chris at C&C Performance here in Kalispell MT is doing work. I should give them credit, they are talented. They have affiliated painter who did mix on engine paint, he did well it seems. He (Mitch's) will do my minor lower L door paint repair in spring, he will spend he estimates most of a day on getting mix right to not do a big "blend & fade" job on car. The aged Revere greenish silver is a toughie. He also is really good.
