Can the stock intake manifold be used on the install of the bc broncos q-jet? Also is there anything that is difficult about the install. And finally will it pass emissions in colorado? It is a 73 EB with an EGR.

my stock intake was two barrell.......so no way!

Our local parts store has an adapter to go from q-jet to 2bbl. It cost $15-$20. I'm sure summit has them as well. I almost put a q-jet on my bronco, but decided to hold out for a stock throttle body off a t-bird or something. Until then, I've actually got my holley working quite well.

If you've already got a motorcraft, I don't think I'd mess with it. They do very well offroad.

I would also be using the adapter from Bc Broncos if that is the type of adapter you are speaking of. I have a motorcraft but it has just quit on me so I am looking at options. Any info on the new Holley Truck Avenger??? Thanks for the help so far.

Any one else have any input???

Those adapters don't work very well. If it were me I would buy a Edlebrock aluminum intake and ditch the stock manifold. That way you don't have to use those crummy adapters and you get a better and lighter intake manifold. You would still have to buy a square/spread bore adapter, but the 4 bar/4bar adapters are more like a carb spacer that the 2 bar/4 bar adapters. Just my $0.02, but I am running a 460 with an Edelbrock intake manifold and I am also about to swap on a Qjet.
