408 original air cleaner dimensions, please?

[Kevin H]

David,
This one looks like it sits quite snug https://www.forbbodiesonly.com/mopar...01-jpg.532225/ .

For what it's worth, the height of your carby is the same as mine - 3.250 in.

Also bear in mind that the bonnet is higher in the middle than it is at the sides where it meets with wings.

If you are prepared to take the plunge and buy a secondhand one on eBay, at least you are the in the right country . If you do find one that fits, you can probably get a replacement post for the centre of the carby. It looks like you could buy a period single snorkle air cleaner for around $100.

Here's a mockup I made of a 17" dual snorkel 3" high that I considered buying.

It might work if I can lower it but probably more likely to fit if I use a 14" dual snorkel. There are separate lowered 14" bases available. Maybe I could cut the base out of a factory dual snorkel one and rivet/solder one of the lowered ones in its place. I'll play with mocking that up today.

Yes but a bit pricey compared to some local (eBay) stuff.

The summit carbie you have does seem very tall and Kevin is right the air cleaner sits very high . My 411 Mk2 (high compression motor ) had a 750 holley on it and performed very poorly and used a lot of fuel. A friend of my brother Geoff who would likely be Australia's authority on all things Mopar strongly recommended going back to an original Carter (Edelbrock) 650 cfm carbie. I took his advice and it transformed the general running of the motor ( very pleased). Since then Edelbrock have released a new series the AVS2.They come in avariety of sizes and finishes, I plan to fit a 1906 to my 412 shortly.
You motor is smaller than mine but is warmed over therefore a 650 cfm like my new one would be ideal . Check the website for dimensions ( the video is worth a watch). One danger if you change carbies make sure you set the auto transmission kick down correctly or you will burn out thr transmission.

Your correct, the point of first contact with the air cleaner is at the front because the bonnet slopes down.

Thanks, Peter. Whilst the Edelbrock 1906 may well improve the drivability, it seems it is 3.25" high same as the Summit one currently fitted. I am going to focus for now on getting a quieter, more stock looking air cleaner on there somehow but will bear the carb change in mind for future.

My US born and bred neighbour who likes loud cars and motorcycles suggested I cut the 'hood and fit a shaker intake'. Heaven forbid!

What a great idea you would be the first Bristol owner to do so. Could I suggest a supercharger and 20 inch wide rear wheels.

Interesting the Edelbrock is the same hight , the summit in the photos looks much higher.

Shall leave you in peace

Best of luck

Peter, just as an aside: how do I check/set this anyway, please?
