Anyone want to comment on it? Personally I dont see how they got the numbers out of it that they did, but if those numbers are true then I might just copy it Here are the specs:

350 block
E-tec 200cc Heads
11.3:1 compression (pretty high)
Lunati Solid 254*/259*@.050, .552/.561 lift, 106* LSA
Performer RPM for vortec heads, 1" carb spacer
1 3/4 headers, dual 3" exhaust
Mighty Demon 830cfm carb

They got 530 horsepower @ 6300 rpm and 482 ft lbs @4700 rpm

I would have thought the motor would have made its horsepower closer to 7000 rpm. Any comments? Do you guys think the numbers are over inflated?

 

I didn't see that particular article. The one I saw was in Super Chevy (I think it was last month's issue) where they pulled 530 horsepower out of a 383. BTW, the cover of Super Chevy said 350 horsepower out of 383.

 

I punched those numbers into DD2000 and got the numbers below.

I don't have the flow numbers for the Etec 200s, so I used AFRs 190s. And you have a choice of either single plane or dual plane, which as you may know, the RPM manifold is kind of in between, so I used a single plain, but dropped the CFM to 750 to make it simulate a large plenum dual plane.

Other than that, I used large tube headers and the exact cam specs you gave there.

I'd say for $35 program, and a little "know how" it's a pretty accurate piece of software.

 

u get what u pay for good machinest and parts.

 

Those numbers are very impressive for a 350!

These are the flow#s on the E-tec heads I saw on the Edelbrock site if you felt punching in these in to see if it changes anything!

I think these are one of the best heads available for the money

E-Tec 200 Part #60989

.100"--- .200" --- .300' --- .400" --- .500" --- .600" --- .700"
67/57 122/110 175/153 223/182 252/196 259/204 265/207

 

Well if you thought 530 was something you gotta see the dyno graph of that same motor on N2O. 710hp with a 175 shot of juice.

How's this???

BTW..... that just show you that AFR really knows their STUFF!!!
They managed near identical flow numbers with smaller intake runners.

Although I have to say DD2000 doesn't allow for the Vortec style chamber's ability to provide an EXCELLENT street engine. It certainly has it's drawbacks.

 

here are the # on my 400....Dart doesnt do too bad either..

 

the seller claims 525 hp DD2000 can be a little generious!

 

one more...the first chart was with open exhaust.......
