Andy, one of my customers(and freinds) used that set up on a pump gas stroker in his wifes car,1968 Charger R/T. They have dyno tuned on a engine dyno and a once the motor was in the car they chassis dynoed it also. They had to rejet the motor down on the chassis dyno for the best performance (HP and torque)after jetting it on the engine dyno for best power and torque I can probally get copys of both set ups, dyno sheets and jetting if you want one I'm not sure on the air cleaner they used on either tests

I run it in my 1969 chrysler 300 and I am very happy with it. Tons of torque - just what you need for a complete set up of 4400lbs. Best ET so far 14@170km/h , 60ft was horrible 2.45. I was running on General Tire street tires with 45psi pressure. So absolute no grip. And kickdown linkage wasnīt right. The tranny shiftet at 3500 into second and at 4400 into third. Normal shift point should be at 6200. And the carbs runs to fat. The heads are homeported edelbrocks. Cam is a custom solid from Scott Brown. 10.76.1 compression, 1,75" headers into 3" system with h-pipe. 3:91 rear axle. Havenīt been on the dyno yet, but car was built to run 12s. Maybe next week I make it to the chassis dyno. To me the air cleaner looks to small too but if I have enough time this winter I want to built a cold air intake system. ps: Like your new book

Any chance you're going to dyno that set-up? I would be curious to see how it stacks up against a Performer RPM with say a 950 Holley or a (gasp) thermoquad. It do look good if nothing else.
Kevin
I am going to dyno it but I'm going to compare it to a tunnel ram. Basically a dual carb showdown. The engine in the picture is a 505 with RPM heads and a hyd roller cam. Heads had a little touch up work done by Dwayne years ago. Motor should make some torque but it isn't a high power setup.

Just got a complete setup from Edelbrock. Cool looking parts but I've never run this combo before. The air cleaner is a little dinky for a Mopar. I think they would sell more of these if the air cleaner was large enough to accept the 440+6 element.
Do you think that maybe a stock HEMI airgrabber air cleaner could fit with some mods?
I don't know about the Hemi, but the early factory DQ intakes are 7 1/8" center-center spacing. New Eddy stuff is 6 7/16" IIRC.
This aircleaner is bigger and would look much nicer with those valvecovers. $70 more than that cheapie chrome one, too, which isn't much in the grand scheme of that induction setup. http://www.summitracing.com/parts/EDL-41...mp;autoview=sku
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields

Andy,
Don Dulmage used to ( probably still does) run that combo I think. He is on here, not sure if he frequents the board much. He is in Canada and I know has ran it for many years. Maybe someone can help me out with his contact info here.
He was running it on a early 70's Sattelite or Roadrunner and ran quite well. HEavy car.

i've had it off and on the car 3 times...i'm having fuel delivery/pressure/volume issues that aren't as bad when i have the single 4 on it,so thats how i finished the season..i plan on changin fuel systems over the winter and hope to start next season with the CH-28..

I predict the only category the CH 28 will be superior in will be hood clearance.
Kevin
It's pretty danged awesome for hood - AND bonnet- clearance!
I run one on my Jensen Interceptor, it's a 9.35 to 1 compression 440, .030" over, ported heads, 270 Comp Cam, and two little Edelbrock 500s. It hasn't been to the track yet but it seems to run really good right out of the box, the idle is steady and solid.
I was thinking of trying two Edelbrock 600s, but the engine is pretty mild, the car has 3.08 gears, and it doesn't have a stroker crank or anything.... maybe I'll change it down the road if it doesn't do what I hope!

Has anyone tried it with Holley carbs or are the Eddy/Carters the only ones that fit??

Nope it's edelbrocks or nothing. And I bet they made it that way on purpose. I looked into this once. No way a pair of holleys would even come close to fitting. Only way to do the dual holleys is a tunnel ram or possibly the early 60's stock dual quad intake? Although it looks so bad for flow who would bother...

last page...11.50's @ 4,100 lbs. He is right, that's mid 10's in an a-body! With parts that many consider "junk".
Not knocking his results(especially back in the day)but the 5000 stall and 4.56 gears had a lot to do with it IMO.

I just finished building a linkage kit for this intake. Nobody seemed to make a throttle bracket or a return spring setup so I designed my own. I'll stock a few in inventory by the end of the year in case anyone else needs it.
Can the factory bracket for the kickdown be used with that bracket??
Nope, I have a Doug Nash 5 speed in my car so I didn't try to accomodate the factory kickdown in my design.

I made an interconnecting piece from flat stock for my carbs, and drilled a hole at the exact location the original carb linkage rod was. I bolted the factory piece in the factory location, and I hooked up my kickdown and throttle linkage bracket to it.... I'll post a pic when it stops pouring rain!

You must remember that setup was a hot setup 35 years ago. It is definately a more street than strip deal. That being said I have run it on 2 Challengers with 440s, 509 cams and 3000rpm stall converters. It is FANTASTIC!!! Great sound and even better looks- plus its a period hop up from a day when more carbs simply equaled more power output. On a 440 Edelbrock says the manifold is an idle to 6000 rpm setup. I love that setup. Wish they made a manifold for the smallblock.
Keep old mopars alive.

Edelbrock DID make a 2x4 inline manifold for a small block - I've seen them personally and for sale on this and various other boards. They're out there..

That is encouraging for guys contemplating the nostalgic look, but still seeking hp. I wonder how a little porting might work? Maybe no carb spacers under the carbs for a different booster signal? Pretty impressive, when you figure it was designed in the days when we were hogging out stock iron heads looking for more hp!

i would expect a decent single plane intake to best the RPM by at least 20-25hp on a 12:1 505" motor, which says to me the CH-28 is down about 40-50hp from a decent single plane(like a Victor).
