Weiand intake but it gives you an idea what the stacks will look like on a BB. It is very symetric.

Good idea Dave.
These have the round holes. They may need to have the diameter trimmed down.
I guess the retaining ring can be made out of flat aluminum.

FWIW, re: those air filters with the black "foam" type filter elements;

Over the last ~30 years I have serviced more carbs than I can count that were fouled by that black foam after it dissolved and "melted" (for lack of a better term) into the carb. Getting that material out of the air bleeds is a real picnic.

I'm not sure what causes this (aside from the obvious carb backfires and subsequent fires), and I've seen plenty of cars that have ran those filters w/o issue, but I feel I would be remiss in my duties here if I didn't at least post a fair warning based on my personal experiences.

Just a heads-up. Carry on.

Good info Eric. We appreciate it. How are things to the west?

Ditto....I was in a Chevy dealer getting my SS Chevelle serviced (warranty work...) in 1970. Another local was attempting to get warranty work done on a '69 SS Nova (L78) with one of those foam filters. The engine had &quot;sneezed&quot; and melted foam was all over the Holley... L-O-L. Dunno if he got warranty. I did (killed a TH400 on the GM 5-Year, 50,000 street race power train warranty plan) [img]<<GRAEMLIN_URL>>/smile.gif[/img]

I was concerned about this. When I break in my engine I'm going to run regular filters until everything get's past the hickup stage.

Since the black foam is so porous and allows everything past except a small bird I was also thinking about running a layer of flat filter material from K&amp;N or some other source underneath the black foam. Iwas thinking of taking one of their flat pleated filters and leveling it out and use this as filter base to catch anything the foam does not filter..which is plenty, plus keep out melted or deteriorating foam.

Running naked carbs at the track is not technically legal unless they're under a scoop.

Backfires are probably the majority of the problem, but I wouldn't rule out fuel incompatibility. Thanks to the EPA, today's gasoline is much harder on polymers than it used to be.

Re: Tunnell Ram Toppers
 

That should work very well. I cut down a large diameter velocity
stack and made a mini flyeye for my Dominator on my Chevelle. I did the same thing you are speaking of. We worked out the tune on the dyno and I installed the air cleaner after that. I've never had a problem out of the foam in all the years it has been on the car.
