408 original air cleaner dimensions, please?

[dwomby]

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

I hate to say it David - but same thought occurred to me about the shaker hood scoop! I did dismiss it though! Hope the air filter box solution works other wise I guess you have to start looking at low rise manifolds shallower carbs and so on. Bet the car goes well with the 360 and hotter cam though.

Indeed it does. Just a bit too noisily for my taste, Andrew.

Re setting the kick down lever I have no understanding of how to, I paid the guys who rebuilt my auto to do it. There is some infomation on the Web but I dont fully understand it. Just be warned

What a horrible thought!

I have ordered a 14" pancake air cleaner (the filter is exposed around the whole circumference) with a recessed bas to lower its overall height. I'll see how that does for fit and a first step towards quietening. I'll report back when fitted.

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