Title: K&N stub stack...any good ? still around ?
Post by: Frank400 on January 12, 2011, 09:36:27 AM
Hello everyone, I'm newly registered here.  In the 80's the stub stack was very popular, at least in magazines.  Is it still around ?  I think it was available for the quadrajet as well but I am not sure.  Any valuable information/testing that exist on these ?

the stub stack is still around but, I dont think there is one for the Q jet as far as I know.
Holley or ELdbrock and a few AFB's. (Someone correct me if I am wrong please). They actually do work.
I was thinking of trying to make one. Jus use the green foam like used in flower arangements and shape the entrance. Then coat it with fiberglass sheets and resin and shape it. the foam can be "dug out" afterwards. It might be worth some experimenting.

Those were very popular back when EVERYONE running a small block Chevy bought a POS 1850 600cfm Holley carb, put it on the $75 Edelbrock Performer intake, and LOST power at every rpm!

The coolest part was the first time you went to full throttle at a stoplight and the engine backfired up thru the carb and melted a big hole in the foam filter element.

I'd like to have $1 for every time I saw this happen back in the day!.....Cliff

I thought a Stub stack was a plastic part that smoothed the air horn out.. Like the one in the link.. http://www.knfilters.com/Racing/stubstacks.htm

I've been doing a lot of research on air filters.. The best is suppose to be the open style that covered the element but was open on the bottom. Smokey used them on the Fireball Roberts Super Duty cars then Mopar and Olds used them in the 60s..
