Default orig. rochestor q-junk or edelbrock carb?

idk what to do. i have a shaker hood-scoop and idk if i should buy a edelbrock carb and intake manifold replacement for stock. would that mess w/ my hood-scoop height? because this rochester q-junk is coming off and i might as well change the manifold while im at it.

I guess that would depend on the intake purchased.

edelbrock carbs are junk, manifolds are good I would highly recommend the RPM air gap for a street setup. get a holley

the rpm air gap will take away low end torque though and as far as street fun low end torque is where it's at

true on the edelbrock carbs though, holley is what to get

the rpm air gap is for low end torque, it's a dual plane..

Edelbrock's Performer RPM Air-Gap intake manifolds incorporate race-winning technology that's been used on Victor series competition intakes for years. The open air space from the Air-Gap design separates the runners from the heat of the lifter-valley cover. So, the air/fuel mixture stays cooler all the way to the heads, which produces a denser charge for more power. Runners are tuned to move the power band 1,000 rpm higher than Performer Air-Gap manifolds, from idle-5,500 rpm up to 1,500-6,500 rpm.
sounds like it's moving power up the band, aka NOT low end

theres 2 air gaps if i remember correct..the performer is for the avg joe and is dual plane..and the rpm is a single plane...the air gap will make more power then just and avg intake do to the fact of the runner design and the gap under the intake witch stops the heat soak from the valley cover going into the runner plenum.

What else isn't stock on the car? If the car is all stock, put another q-jet on it. They're not as bad as people make 'em out to be as long as you're just cruising in the car. I got 200k miles out of the one on my '87 Caddy before it took a shit, and now I'm running a junkyarded replacement with God knows how many miles on it. The q-jet on my '79 Caddy is fine too.

^Agreed. For under 400cid, a properly built q-jet will make more hp than a holley any day of the week. Look at superstock
