Who's Running an Edelbrock CH-28 2x4 Intake on the Street?

[PROSTOCKTOM]

Thinking maybe I need one of these on my 499"RB. Wanted to see who's running one and your thoughts.

Currently I am running a ported Victor intake and know that I'll give up some performance if I switch it out, but they just look to cool to not inquire.

Only interested in hearing from guys that have real experience with them.

Thanks,
Tom

I had one on my 66 coronet with two 600 Edelbrocks. My 440 was 9.4 to 1, hughes 228 232 @50 cam. Headers and some head work. It ran well. Very responsive. I first had progressive linkage but it was much more responsive with both carbs opening the same rate. The only issue I'd get was some poor running if I was in traffic on hot days. The carbs would boil. As soon as I got moving it cleared out. I ran it on a drag night for fun with 3.23s and street tires. I believe my best was 13.36. That was with points distributor and my trans was not optimal.

the linkage and gas pedal still factory smooth or was it stiff?

I had a lokar kick down cable and throttle cable. It worked just fine. Pedal pressure was normal.

cool, I'm with you tom, cool factor it'll look awesome, I bet it would work great for a torque monster stroker. 2 thermoquads? wow

I don't think two thermoquads would fit that intake. The carbs are very close together. Unless you made some offset adapters

true, they are monsters

 

[PROSTOCKTOM]

I need to figure out which adapters I need to buy so I can use the wide bolt pattern that OEM AVS carbs have.

You would have though Edelbrock would have updated the carb flanges, but why I guess when they can sell you $200 worth of adapters.

I had a 505 with a Comp 292HR cam, ported Eddy heads and that intake. It was a great engine. Made 600 hp and 600 torque. Was super smooth and pulled hard.

That is a good looking set up.
I like the air filter assy.

That engine had a set of heads that you ported. Edelbrock heads and you did some bowl work and valve job and got them up over 300 on the intake side. It was a long time ago, maybe 2008 or 2009?

I wrote some articles for Popular Hot Rodding on this engine but sadly I don't have links anymore. I think they blew all that stuff away when they nuked PHR magazine.

I dug around the internet and found the article that I wrote a million years ago: https://www.hotrod.com/how-to/1007phr-big-block-mopar-engines
