Intake Q ?'sEdelbrock Performer RPM manifold ( E Body )
Does anyone know if a Edelbrock performer rpm manifold will fit under the hood of 1970 Challenger 440? Also will this manifold require a different trans kickdown rod/ carb linkage? Right now it has an old Holley 3310 with the stock cast iron manifold. As you can tell I don't have much experience with motors yet. Any help would be greatly appreciated.
The RPM is pretty tall. I think you would have to alter the throttle bracket and KD linkage to work. Here is what I built for mine.
The RPM is a tall dual plane. I had to go to a drop base aircleaner and it barely clears the hood of a 70 Charger. Not sure how that correlates to an E body. Do you have a bulge hood? It is almost 2 inches taller at the carb base, and you will need to fabricate or buy new throttle and kickdown linkage.
Hey Mike, I saw you heading down the road the other day over in Tualatin. I waved but I was in the Lexus so you probably didn't notice!
Maybe if you keep the holley it will fit, I doubt it will w/an edelbrock carb like 451's pic. I had the rpm on my 383 (low deck) and could only fit 2" cleaner on top of the edelbrock carb., due to the electric choke. Finally switched to holley and was able to use 3" drop base. BTW, the powerbulge doesn't really give much more clearance because the support bar runs right above the carb.
If you have the bulge hood, you can easily run the RPM intake, a Holley carburetor and a drop base air cleaner with a 4" filter. The throttle linkage bracket should be modified to make it safe and bind free. My kickdown worked o.k
What kind of hood clearence do you get with Edelbrock RPM intake
This is for a 383 with stock dual snorkel
How much higher is the Performer RPM ?
I measured, it's 1 1/2" taller than a stock intake. Fits on my 71 RR with a 440 and a drop base air cleaner.
I have a 68 SuperBee with bulge hood and stock unsilenced air cleaner. Just bearly fit but it does fit. Hope I never break a motor mount under accel. :>
i have 0 hood clearence have to cut hole in hood with scoop on 65 coronet w/440. i think a 70 would be ok.
Wow, 1 1/2" taller than stock...Sounds like a tight fit to me.
I currenlt have a stock intake, 1"
Thanks for the input,
Don't forget you will have more clearance with your 383 than with a 440. You can probably leave the 1" spacer off too. Measure your clearance with your current setup to see where your at.
69 RR carb air cable clamp?
installing the airgrabber cable "carb air" from the interior to the underhood ductwork. the cable clamp and screw at the ductwork is missing, the cable clamp receiver part is still there. any ideas where to snag one or does anybody out there have one laying around in their toolbox stash? any other cars use this style of clamp?
If you need one Snook I have a bunch in my spare parts bin. Shoot me an email and I'll send you one. Have enough clips for the cable that goes between the two flappers? There's one on each side....
if you can't find the clip,let me know,i'll drive over and take the hood off your hands!!........lol
Black Sheep: thanks for the offer! i found a couple at the junkyard on saturday though. the first time in many years that it's worked. now it's time for the dana swap!
Snook you do know that the Dana 60 requires a shorter driveshaft to change over from 8 3/4 .I see you been busy after gettin the electrical stuff out of the way.Got your car painted way to go it looks good.You can ask around on here as I dont know the measurements .But if Im not mistaken the Dana has a shorter drive shaft due to the front of the Dana 60 is large and protudes forward
WingCars: nope i didn't know that! how much should i shorten it? anyone have the exact specs?
According to the dimensions in the Direct Connection chassis bulletin, the centerline of the axleshaft to the centerline of the u-joint is 1.12" longer on a Dana 60. You should shorten the 8 3/4 driveshaft that amount....
Factory 440 intake question. 67-70 - Which one should I use?
The 67-69 440 HP intakes were 4 hole design and the 70 HP intake had a side by side oval flange. Both types were dual plane. Why was the intake re-designed for 70? Any difference in Torque or power from the 4 hole to the dual oval design?
If you choose to use the 4-hole manifold make sure that the size of the primary and secondary throttle openings of your carb match in size.
