Part #?

Posts : 4294 Join date : 2009-12-16

Does anyone have a part number from any manufacturer for the manifold to cat flange stud and nut on a stock LT1? Also is there any trusted/go-to 3 bolt flange gaskets you can recommend? TIA

3/8-16 on the manifold side and metric on the cat side, I forget the size. I just use 3/8-16 studs from the local hardware store. I think Dorman has an assorted pack with 3/8-16 studs in the pack.

Fel-pro has changed to the paper looking gaskets. Last time around I got a different brand from Autozone.

I got the numbers I was looking for and ordered them from napa.

Ok never mind. The napa studs that came are pretty far off, not even close.

10220453 ? Maybe I was wrong about the metric/std but that's what I remembered from that other forum. Oh well 3/8-16 worked for me.

I read that whole thread. I put the nut and gasket part #s into the link you provided for the stud on GMpartgiant. I wonder how different the GM gaskets will be compared to what I got from napa. Thanks a ton for the info from the way back machine!

The napa parts #s I was given are

Gaskets: FPG 60988

Stud kit: 600-1816
