Hello guys just got my new edelbrock performer 2-0 intake. The ports look small it is going om my 402 .030 over 9.5;1 comp. Comp Cams 270H 224Duration 510 lift. Early oval port closed chamber heads. It pulled 403 hp 460lbs ft torque with OE Carb & intake on dyno the flat cast iron intake.Will this intake the performer 2-0 give me any performance gain? Will be using a new rochester customed tuned by Sean Murphy induction. thanks for any thoughts!

Gary,even with the small ports it will out perform the stock pancake intake.
I ran on my 454,turned a best of a 12.99
I recntly swapped to an RPM,but haven't been back to the track yet.

Mr 4 speed you ran one on a 454 a pulled a 12.99 in quarter? What hosre are you running? Any one else have any comments on the subject please chime in. I am concerned that it is a waste of time should i go with the RPM? wanted to keep it stock as possible! THanks again MR 4 Speed.

I like the RPM...paint it orange and noone will ever know smile.gif

Slightly off the subject...I used RPM manifold on a small block, painted it orange and even had the old style oil filler tube installed in it. It looked really stock and fooled the eye when glanced at.

Gary,

Personally, it would not be my first choice for a high performance motor. I am using one on my 408 motor, it was on the car when I got it. But if you want to go with a Q-jet, you don't have too many options. I did a little port work on mine and opened it up to match the oval ports on my heads. It seems to work good enough. My cam is a fairly larger and it still seems to work ok. I think what you have is marginal to gain much from the RPM (I am assuming you would buy the RPM for the QJ). You probably will not get much more than 5500RPM from the 270H cam, so the 2-0 should be adequate.

By the way, those are some impressive dyno numbers. Would like to get some more detail on the dyno run. There has been a number of ongoing discussions regarding power output of a mild 402 motor. Like I said, I run one and have never expected anything over 380-390 HP with a mild flat tappet cam. Nice to be proven wrong!

Thanks for all of your replys! So do we all agree that the performer 2-0 will give better, noticable power improvement over the stock cast iron 1972 402BB intake? And my combo realy is not radicle enough to warrant the RPM.I Have a CI hood and do not nned clearance issues, Thanks again guys!

69chev I will get my dyno sheet tomorrow and post the info here.

im not sure if this helps.....but i thought i would throw it out there.....last summer i was going thru intake swaps and cam swap like you wouldnt believe......i was trying to get a combo that would pull a 3900 lbs car with 2.41 gears off the line and be impressive......during the parts changes and track times i came up with this conclusion.......the stock low rise intake perform very well i thought for what it was.......it pulled well down low and didnt seem to give to much up on top end.....but it did have a spread bore carb then i tried a 3310 with an adapter plate same bottom end just alittle more on top.....i changed intakes to the old streetmaster eddy intake and used same carb the bottom end (60 ft times) stayed in the same area but the top end i was able to get a few more mph.....i was turning 6000 rpms during my 1-2 shift..........i then switched to a old torker 2-0 intake with the same 3310 carb......this still was giving me the same kinda 60 ft times (2.24-2.30) as like the other intakes........my top end was improving from 92-93mph with cast iron low rise spread bore,cast iron with adapter plate an 3310 to mid 94-95mph same with the the streetmaster and the torker 2-0 low rise intake was giving me 97-98 mph other changes was made to the car and it was running 104mph plus with same intake and carb and i just put on the rpm intake from eddy and i do know it feels so much better down low....even with gear changes from 2.41 to 2.73 and stall changes from 1600 stock to 2100 and then a 2800 rated stall and with about 6 differnet cams....the cars worst 60 ft time was 2.30 and with a best of 2.15....and the last outing was best of 2.20 .....so it seems those intakes must be pretty close down low.....but the rpm i know has the best bottom end and i will shortly find out........

as far as im concern the low rise intake wasnt that bad i ran it as well on a 396 with 7.7 to 1 comp. motor with a 272 crane cam and with a 650 holley it was turning 99 mph thru the traps and i ran the eddy performer next and didnt see no noticable gain in performance with such a mild 396 turning 5500 rpms........
