If I were to get a replacement carb for 1967 442, Should I just Chevy style inlet? To the side and not straight on. The issue is a stripped out filter housing thread.
All searches of JET models call for a Buick/Olds version with straight inlet.

Your filter housing thread can be repaired through a heli-coil process. I've had it done on the original carbs for m '68 and '69 and it's worked beautifully.

The correct 67 442 carb had the side facing fuel inlet....and the divorced choke. Somewhere around 1970 the quadrajet for the Olds switched to a straight fuel inlet.

Those inlet housing Q-jet re-thread kits are available..Fact I got 1 sitting out in the garage never used...

here you go

1968, actually.

joe_padavano

Yeah, and you get to use those exactly one time.

To the OP, the original 1967 carb was a side inlet, just like a Chevy. The correct carb number for a 49-state 442 was 7027156, and for Calif cars with A.I.R. it was 7027157.

X2 yep! Each one has a different size inlet for the fuel line from the pump. I guess depending which Q-jet your going to mend...Have not seen any for the earlier Rochester 4-jets...324, 371-394's etc..

Ok great. Thanks for the confirmation. I have extensive experience with big and small aftermarket Chevy builds but not much with Olds, which really is my favorite though. Ive had a few over the years but couldn't seem to hold on to them cause of the expensive parts! Had a 68 455 Delta Custom and a 67 Turnpike Cruiser. There was too much deep engine work and I couldn't keep up.
This 442 is in great shape cosmetically but has a lot of the same problems, crappy idle , likely due to mangled exhaust seats and worn out Q-Jet. The cylinder pressures in this 10.5-1 400cu in.
motor are all around 175psi.
Does that seem halfway decent to you guys?

Those are not the same as an "heli coil" repair. That is a one time "repair" that possibly will ruin your Q-Jet.
