OK I am seriously considering this setup from edlebrock

it is Performer rpm Air Gap... edl-7501

Performer Rmp Heads.... EDL-60999 64 cc combustion chamber 2.02 intake 1.6 exhaust 170cc intake runners 60 cc exhaust

Performer RPM CAM and LIfter Kit....EDL-7102 488/510 lift at the valve 234/244 duration at .050

Performer Series Carb...1407 with Electric choke
750 cfm

This Kit is supposed to pull 420 HP and 415 Ft Lbs of torque...


should i believe it.. i m looking at the dyno chart in the Edelbrock catalog... the whole kit is gonna cost me around $1,685 Shipped from Jegs..... Sweet deal... or too good to be true?????

 

any thoughts greatly appreciated

 

i'd skip that cam. I also wouldn't go for that carb, I think that performer carb is a vac secondary, with a not-so-great reputation.

The heads and intake are pretty good for a street motor I think.

 

i'd change all that to vortec heads, comp XE274 cam and a 750 DP holley carb. that will net the same power and be much cheaper. also get the rpm air-gap vortec intake as well.

 

if i m not mistaken you posted in my summit heads thread.... and i seriously looked into what you said... with the cam being a retro fit roller cam that cost aout 230 sumtin if im not mistaken was fine and all but a set of lifters cost me about 450$ thats almost 700$ right there..then i had to buy a set of heads figure the vortecs from summit fully assebled were 515$ i think... thats thats about 1200.. tehen i have to get the intake for about 215 there thas about 1400.. then theres the carb... and that if i am not mistaken was 245$ at my work.. but cant check now because yesterday was my last day...(moving in a week) but anyway alltogether there with a ballpark figure is 1645$
for another 40 bucks ive seen the dyno chart ( i know its not really running the dyno in front of me ) and know whats its supposed to pull. its doesnt have the guesswork...and there all not matched to each other like the parts from edelbrock.......hey whatever this looks like to you....i meant no disrespect. just stating the reasons why i didnt go with that the first time ...

 

the cam is $169 with lifters from summit. it is NOT a retro-fit roller cam, it is your basic hydraulic flat tappet cam. Heads machined for extra lift are $550 for the pair through scoggin-dickey parts center which are the way you need them for that particular cam.

 

really?????? the cam i looked up was roller ..... maybe i just told them the wrong part number... yeah but foreal i meant no disrespect

 

That's not a roller. It's garbage. It's also overpriced: you can get the identical same cam in the Summit brand, Melling, AMotion, SpeedPro, and on and on and on; any of which is cheaper than buying it in an Edelbrock box. Like this. Nobody in his right mind would pay Edelbrock's price for that POS. Also, given that it's about a 35 year old design, virtually ANY modern cam of simialr specs will outrun it. Or, looking at it from the flip side, virtually ANY modern cam that produces the same power, will get better gas mileage, be easier to tune, give less driveability problems, have higher idle vacuum, and so forth.

The RPM heads are pretty decent, for a street motor. They're not designed for max power or all-out racing, so don't be expecting that. Instead, they're designed for good high-RPM flow without sacrificing too much low-end torque; compare their 170cc ports to, say, AFR 195s, Trick Flow at about 195, etc.

I also agree about the Edlebrock carb. Carter carbs aren't a performance carb at all; and in the 40 years since that particular design came out, alot of improvements have been made. Like the cam, you can do ALOT better.

I think if you used the Edelbrock heads, a Comp 270HR or 276HR hydraulic roller cam, a Performer RPM Q-Jet intake, and a Holley 6210 or 6211 carb, you'd have a VERY GOOD all-around street performance setup, that would still get nearly stock gas mileage on the highway; and wouldn't require 4.10 gears just to be able to pull off from a stop sign.

 

depending on your cubic inch, and compression, 170cc intake chambers might be a little on the small side. if your completely puzzled, look in magazines about 383's. there are easy ways to make 500 hp for under 5000. and they walk you throught it. tell you exactly what to use. also, talk to people at your local speed shop, or machine shop. the worst thing you could do is buy these parts without talking to anyone and then getting the dreaded "oh, you would have made more power if you did this."

 

Hey 85T/A we built a similar motor for a customer a few years back :355 flat tops, rpm heads ,750dp holley, comp 280h (non roller) MSD ready to run dist slp headers dyno tested @ just under 400 hp so with a bigger cam and maybe some long tube headers and the air gap it would make the 420 HP

 

hey was that at the crank or at the wheel hopefully the whell probly the crank.. any way whic is it lol Just curious
