Edlebrock C4B Intake - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**DreamRyder1963** · 01-11-2014, 10:36 PM

I picked up this old Edlebrock C4B intake in hopes of swapping it out with my Offenhauser 360 degree intake. I am looking for more low end torque. My problem is that I am concerned that this intake will not work with my HEI. Does anyone have experience with this intake?

I think that it will clear with no problems. I have no experience with that manifold though. It is older than I am! You may be able to make a few bucks from someone doing a 60s period build.

**DreamRyder1963** · 01-11-2014, 10:50 PM

If it doesn't clear that will be my plan. The part I'm concerned about is the rear runner. It seems to be taller than on most intakes.

Just measured a HEI dizzy. There is 2 1/8" from the bottom of the mounting pad to the base where the cap goes.

**DreamRyder1963** · 01-12-2014, 12:25 PM

I just measured the space on the intake. There is only about 1 3/8" on space between the runner and the outer edge of the hole.

oldschool18 · 01-12-2014, 01:38 PM

what is your height clearance?

**DreamRyder1963** · 01-12-2014, 01:52 PM

The runner is about 2" tall at an almost 90 degree angle.

oldschool18 · 01-12-2014, 02:32 PM

I think burnin oil meant you had 2 1/8" clearance in height?

**DreamRyder1963** · 01-12-2014, 02:56 PM

If thats the case then my distrubitor might fit. I think I have a spare at the house that I can test fit. I read on a different forum that someone had to grind off some of the runner to get to fit correctly. I might just clean it up and flip for an Edelbrock Perfomer EPS.

Tx Firefighter · 01-12-2014, 04:29 PM

I restored an earlier one that that, a C3BX for my 327. Cleared the HEI just fine.

**DreamRyder1963** · 01-12-2014, 04:34 PM

How do you like it Tx Firefighter?

Tx Firefighter · 01-12-2014, 04:40 PM

I like funky old parts. After running it a while I changed it to a Performer RPM, but I had other reasons to do so.

**DreamRyder1963** · 01-12-2014, 04:47 PM

How was it on low end torque? That is my main objective right now. My current intake is gutless when it comes to low end power.

Tx Firefighter · 01-12-2014, 04:51 PM

I never had any complaint on the bottom end torque. It would blow the tires off at will.

**DreamRyder1963** · 01-12-2014, 04:54 PM

Sweet thanks for your input.

I've had an old C4B in the garage for over 30 years. An HEI distributor would not fit when I tried the combination on a 79 El Camino that I had at the time.

**DreamRyder1963** · 01-12-2014, 08:04 PM

I'm pretty sure I have an old dizzy lying around I will mock it up later. I'm only in it $60 so I am good either way.

bigguy69 · 01-12-2014, 08:38 PM

I had that same intake. Mine cleared no problems with hei.

**DreamRyder1963** · 01-12-2014, 09:27 PM

I just tested the intake with the distributor. The edge of the base hits the top of the runner. It's just barely off probably no more than 1/4" of need clearance. I will probably just sell it and get another type.
