Hot Rods Edelbrock C4B, C3B and C3BX

Thanks for posting . It is good to refresh the old noggin.

 

Thats cute! Moriarity arranging his manifolds like we would arrange our socks!

 

I have one of the C4B intakes and wonder if anyone has ever used one with an HEI distributor? And, also, what tricks were used to do so. And, yes I already know GM made a small version but I'm not interested in using one those because of the 'why' the larger one was designed in the first place. Also, I want to thank Moriarty for being generous with photographs of his N.O.S. parts. (Neat Old Shite)

 

Another to note on those intakes is the hit and miss of there being spots to mount a coil on the intake, the C3B sometimes had it, sometimes not.

 

What ever happened to the Corvette Creitz switcheroo?

 

I've always wondered what the rationale was for one side having individual holes and the other having conjoined holes? The Corvette dual 4 bbl manifolds had all kinds of combinations including (IIRC) a dogbone configuration going diagonally. Maybe to equalize the booster signal between the two planes?
Thanks for the pics, I honestly never really looked at the C4-C3 family that closely, they did a bunch of redesigning didn't they?

 

Funny how our onboard Random Access Memory works (and doesn't work) as we get older. My wife and kids marvel at some of the useless crap I cough up from memory but I'm usually confounded by the stuff I want to remember but can't when I need to.

 

Thanks Mark !
I've had a couple of those on my engines over the past 50 years.

 

Thanks for posting.......

 

Fun stuff. I have a C4B somewhere, I think. Bought it In '75 for 10 bucks.

 

Just for the sake of comparison how did this compare to the above Edelbrocks performance wise ? This is an ebay listing have not seen one in decades.

 

Cool! The C3BX os my fave 4bbl SBC intake. The runners are huge, it works great!

To complicate things, here's my C3BX with the more equal length runners. It looks just like the C3B posted earlier. What do you make of this @Moriarity ?

 

Very interesting Mark. Seems there were a lot more versions than I knew of. I ran a C3b for years, someone had filled the notch. Now I'm running a C4b with the 4 holes. Both of them had the oil fill tube pointing to the passenger side. I see all of yours point left. Were the C3 available at the same time or were they replaced when the C4b came out?

 

This is the greatest "not for sale" ad .. I've ever seen !!! Way to go Moriarity !

 

I just rebuilt a 260 with a C4B and my Petronix flame thrower HEI would not fit. I had to put the stock distributor back in and installed a petronix II in it because the stock distributor is so much smaller.

My dad ran a C3B for years , still have it but the plenum notch was milled....I have bought and sold a few and they came with oil fill tubes going both ways.

 

Looks like I have another slight variation of a C3BX.

 

Hmm...I don't remember for sure...will have to look and report back.
