Another clue to the 3.90 gears is the HD Radiator...mandatory with 3.90 and steeper gears on A-bodies. Last year for factory available 3.90/4.33 gears...though I'm not sure 4.33's were actually...

66sprint6, That looks like a '73-up A & B body 4-bbl air cleaner unit. They also use the AC-212 filter.

Here is the '68 single snorkel air cleaner on GTO's and 428HO's. The snorkel is longer on these and aren't double flared at the snorkel opening like the OP's unit.

I'm thinking they must be repopped and available from our host (Ames)...but I have not checked to see if that is true. If not, they shouldn't be that hard to find...hopefully!

Bruce, I'd opt for a new 3.08 gear behind your 455. I have a new 3.08 gear (Yukon) & Eaton posi unit in the 12-bolt (McKinnon out of a '70 GP) in my '70 Lemans with a 461 with an M-20 4-speed trans....

You'll be fine with the 2.25" outlets. My stock 455HO did pretty good on the dyno (430 hp @ 4900 rpm/535 lb-ft @ 3500 rpm) with factory original RA manifolds with 2.0625"/2.125" outlets, so your...

Kent, Might as well ante-up for the 2.5" outlet RA manifolds since you are going that route along with the Pypes mandrel 'X' system. Can't go wrong there and it will support more power down the road...
