C454 intake manifold?

Anyone ever use the old Edelbrock C454 dual plane intake with 4500 dominator flange for BBC rect. port with any drag racing success? Just curious cam, rear gear, and converter selection.

Hi Bob:

I used one on a 468 big block and surprise, it worked really well. I've heard similar comments from other guys that they liked it better than many of the single plane manifolds. Better torque was the common comment. You can probably run a little less gear. A good 1050, 3 circuit Carb Shop dominator was what I used.

Good luck......

Bob

Thanks Bob I guess this was the go to manifold back in the 80's with the Orange county SoCal Pro gas guys. Fabbro said he ran the C454 with 5.14s at 7500 rpm and it was still pulling.

I ran one on a 2900lb chevelle with a 482 bbc, 4500 converter and 4:88 gears. Best 1/4 et was 9.69 @ 138. This was in good air with a turbo 400.

They work very well. Don't forget to cut the center divider down about 3/4 inch.

Great intake for smaller inch engines.
We did a test against a Team G when they first came out, it was a .03 difference.
2600# Camaro, Lenco 4-speed, 5.13 gear, closed chamber 427, Crane roller, running 9-teens @ 151
Put one on a similar 427, flat tappet, TH-400, 5.13's back half Camaro, about 3400#, running mid 10's

?? Was cutting the divider down a common thing to do when using for 1/4 mile?. That would take away a little bottom end and help on the top end?

That's the prevailing legend, it's fine out of the box.

Or, you can tune it as is, then cut it and see if it does anything.

You can also accomplish the same thing with spacer(s).

Yes, that is correct. Take a look at the Edelbrock 7163, which is a current dual plane Rectangle Port BBC intake, (although I don't know if they make one with a Dominator flange). It has the plenum divider cut down on it, I believe all of the Performer RPM manifolds do. And you know they did a ton of testing to determine that was a worthwhile modification, otherwise they wouldn't spend the money to machine them that way. A lot of the old race engine shops used to do that mod for guys, before you could buy them that way.

Actually footbrakejim the C454 intakes all came with center divider cut down 1/2" to 3/4". They came that way from Eddie.

LOL No, It's going on my car as we speak, I really appreciate all the reviews plus a lot I gathered. I'll let you know after Bakersfield how it works. Some said it idles very smooth and more consistent.

And for the 4150 guys, the C427 is identical except for the carb flange

I've been using mine since 1981 mostly with a 9375 1050 4500. 12:1 433 BBC solid roller 702 lift 262/270 @.050. T400 trans, 4.88 12 bolt and almost 3,000 lbs with me and some ballast. 9.650 qtr and 6.04 1/8. Dynoed some single plane stuff in the mid 80's and no difference.

Good Morning Bob:

Modifying the septum divider as mentioned does help, I cut the divider down in the C454 that I used.

That is very surprising and impressive.

-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.
