How much horsepower could I get with the Edelbrock Performer RPM Power Package for my 318 Mopar?

I just bought my first muscle car, 1971 Dart Swinger. 318 2bbl. I am thinking of all the parts of the power package for the small block Chryslers. The entire ackage is outlined on Edelbrock.com. Cam and lifters, carb, heads, intake and timing chain kit. I know the cost of the parts, but I dont know what the horsepower might be put up to, and that is the important number. These are my stats from factory; 230hp @ 4400rpm 320ft.lb @ 2000rpm. Thank-you in advance for your help. I will leave more information if needed.|||My experience with edelbrock cams shows that if you use them you can wind up with less horsepower than stock.The edelbrock performer rpm airgap intake is excellent.The edelbrock heads other than being aluminum are more of a stock replacement head than a high performance head.A good set of 2.02 318 swirlports will out perform them.A holly carb is much better for making power with than the edelbrock carb.A crane cam or an erson cam is also better than the edelbrock ones from what I have experienced.Do a little research and maybe get yourself a desk top dyno so you can run a couple different combos to see what they net you in hp and torque.|||anywhere from 25 to 100 hp gains providing you get the right package if you turbocharge it you can gain the 100+ HP easy|||IF its number matching?


dont touch anything or you'll ruin the value|||I did all that to a 318 in 1974--not worth it--a stock 340 could beat it.|||10-30 horsepower gain.by the way 318s are bad a**,|||If your compression test says you have good compression on all 8 cylindars, I'd just Upgrade, just the Intake, Cam %26amp; Lifters.





For the Intake, a good 4-bbl intake like an Edelbrock RPM Air-Gap or an older used LD4B.





Carb, on a 318, an Edelbrock 650CFM AVS jetted to your altitude.





You'll be able to get a moderate gain from using a Comp brand or Crane brand cam and lifters.





Racer Brown cam's will custom grind anything you want and Jim is of good help also. I recommend them the most, but, a lot of people like staying with major brand. Message me if you need his phone #.





When you call tech, they will need to know what intake, carb, transmission and rear-end you have or will have, and how you want the car to perform. From there, they can custom match you to the power and performance you are looking for.





Have fun.|||ok dont forget first of all that 1971 numbers are "gross" numbers..meaing rated power was done with a harmonic balancer only. todays numbers are "net", so figure in a loss of nearly 20% to be apples to apples.


back to the question....couldnt find a # for the 318. guesstimate of 340 sounds about right. make sure that you get the other components needed i.e. torque converter or clutch kit, a differential that will survive etc.


i built my chevy 400 loosely around the rpm package. i changed the cam to a bigger comp XE284 and went with a slightly bigger holley HP carb. i really like the edelbrock parts. high quality, good warranty, and most of all MADE IN THE USA!!! get that dodge all american made...


ps i work for dodge and own 3 of them too...
