Question Spreadbore intake question..

Stupid question....
Can I stick with an Edelbrock spreadbore intake if I swap a Qjet for a squarebore Holley? Is it just a matter of using the correct gasket\spacer?

Looking at this Holley for sale locally: http://www.summitracing.com/parts/HLY-0-80508S/

Re: Spreadbore intake question..

I have run square bore holleys with the adapter plate on several SBC, but never in a first gen Camaro.

Depending on which hood and air cleaner you are running you might have a height / clearance issue.

Yes either will work. Square bore w/ adapter or a spread bore.
As for the height, I had a VicJr. under a flat hood with a dropbase filter. You should be fine

Re: Spreadbore intake question..

As said, yes you can. Adapter plate is thinner now than before.
Mount intake and carb, then add a cylinder of clay and close hood.
Open hood and check height.

Re: Spreadbore intake question..

The Qjet and Edelbrock 3" air cleaner don't quite make it to the cowl opening now. I can just see the top of it from inside the car.
Alright... it can be made to work then.


This should work just fine... http://www.autozone.com/autozone/acc...er=228351_0_0_

Re: Spreadbore intake question..

I've used a stock spreadbore intake with a one inch adapter and Holley plus a 3 inch filter in my Camaro before. The Moroso air cleaner base had a half inch drop around the carb.

Re: Spreadbore intake question..

Have had a holley sq bore base plate with a Impco 425 carb on a performer spreadbore valley cover for 20 odd yrs
The spacer should have the divider plate in it.
I was able to mill a good 5mm off the spacer, which actually had the spreadbore base fit far more accruatly...like port matching.
used a drop air cleaner and the hold down bolt was/is so close to the hood it rubbs the paint off after a few weeks.

My Spelling is not incorrect...it is creative

Re: Spreadbore intake question..

Not sure what Edelbrock intake you have but if you have either the Q-Jet Performer or Q-Jet RPM Performer from the last 10-12 years, you can run either a spreadbore carb or Holley. No adapters needed. Here's the Q-Jet RPM Performer:

Notice the two sets of bosses for mounting either style carb.

Re: Spreadbore intake question..

Right... mines a little older. The Smithsonian called once and wanted to use it in their museum.

It's a 7101
