While looking through the norton cabinet of my dads garage, i came across two finned pieces with bolts that looked like they could be intakes, later i found a print ad he had from the early 90's trying to sell the bike, and under spares included it listed "dunstall intake manifolds" i've search around google, and can't find any info on any dunstall intakes. I found one ebay auction that looked like them, and said MCA intakes. Any one know anything about this or anywhere i might find info?
Thanks in advance

They are probablyjlust universal finned intake extensions.

Those are a great idea and the increased intake manifold length is probably the cheapest torque/HP improvement you can make.

Manifolds (32MM) are just like the ones on my 68 Dunstall Atlas...+ matching intake and exhaust covers.
Supposed to be generic hot rod pieces of the era...but used and sold by Dunstall also as listed in their catalog.

webco made a similiar manifold item for triumphs/BSA 's - they just didn't have the one edge cut down (unless they made some for Nortons which i am unaware of)- i imagine due to carbs being closer on norton head than T120/A65

Good stuff! Maybe best for an Atlas.

Aw man! Those are gorgeous, I love this stuff for some reason.
I've got the velocity stacks, now I gotta find the manifolds.

Don,
let me know if your interested in the pair, i don't think i will end up using them. Was probably going to put them on the for sale board on here. I found them in a cabinet my dad had full of norton parts, and there was also a sale ad he made from 1990 when he was going to sell it which is where i saw them listed as dunstall intakes. I thought he also had the original air cleaner parts in there but the center piece is missing at least thats the cheapest of the 3 parts to buy
