I am looking to buy some new heads to match a 500hp 355 or 383 ci.

I found 2 set...E-Tec 200 (Alredy have the intake vortec) or AFR195.I whant to keep the combustion chamber in the 64cc range.For use with a XR282HR cam with 1.6 rockers....

The flow chart at 28 h20

E-Tec 200 intake 2.02" exhaust 1.6" 64cc chamber .650 max lift

Help me make my choise
Thanks

 

AFR 210's would be the head of choice for what you have listed.

 

Take the edelbrocks.

 

I'd go w/ the Edelbrocks. I personaly don't think AFR's are worth the $.

late, justin...

 

I'd run the Edelbrocks. I personaly don't think AFR's are worth the $ - you have the intake and everything ready to go anyhow... for the difference in flow #'s you'd probably wash w/ the extra 4 cc loss of compression for the AFR's - very little diff. even w/ the compression, and the extra cost for the heads, plus a different intake.

 

I think will goes with the edelbrock ...Thanks

 

I don't think that 4 cc's extra compression is going to make up for nearly 20 cfm at mid lift numbers. You have to look at more than peak lift numbers.

 

I see the mid-lift numbers, what I'm saying is that if you built both combo's, I don't think the difference would be enought to warrant the price difference in the heads, and buying a new intake. Besides, that cfm can be picked w/ a little port work. That makes the AFR combo even more money, for nothing...

later, justin...

 

You guys need to do more research. The edelbrock exhaust numbers are with a pipe, the AFR's are not. The AFR 195 is an all around superior head. They are CNC'd and they pretty much flow out of the box as promised. Edelbrock heads usually need a healthy cleanup to get them to where the flow numbers you are promised out of the box. Also, if you go with a vortec style head you will limit yourself on intake selection.

 

I totally agree more that the AFR's are the far superior head. Everything I have read from people that bought them says that they are well worth the money. He did say that he already had a vortec intake though which is what made him choose the edelbrocks.

 

The one thing that you are all missing is that typically Vortec style heads make a lot more power than their flow numbers would indicate. This is due to their superior combustion efficiency. I agree the AFR's are great heads but as far as the most efficient, it would be the E-Tec's.

 

Werd!

I'm not sure where this talk of AFR supremacy came from, but I can say from experience that the E-Tec 200 head rocks right out the box.

AFR heads are good no doubt, but superior?........ phooey.

 

may i make a sugestion what about a set of pro toplines

 

Edelbrocks design of the E-tec head is much better then the plain jane AFR's. AFR is behind the times on their combustion chamber design. I would get a bare set of E-Tecs then build it to your own specifications. I dont' like the valve/spring combos that any of the head manufacturers use out of the box...

 

I am confuse again... ... I will change my intake if i need to!!!! What about the Victor jr heads they say 530-580 HP out of the box...I think the victor jr intake would be just great!
The Edelbrock vic. jr heads are cheaper then the AFR 210

As Tested by CHP

Victor jr 23 AFR 210 Race Ready
intake exhaust W pipe intake exhaust W pipe
.2 123 108 111 140 115 118
.3 173 141 145 197 148 153
.4 219 178 180 240 180 183
.5 255 194 198 271 198 200
.6 275 203 206 279 210 210

 

You dont need a 215cc head to make 500 HP on a 355 or 383. Having said that, keeping a smaller runner*d* head will keep velocity up, making the car fun to scoot around in.

My vote is for the E-Tec 200s. They are readily available, priced fair, and you can reuse your intake. The only thing I would do is a good port match on your intake.

HTH

 

How many cubes you gonna run?

How big a cam you gonna run?

What intake you got already?

You gonna run it on the street?

What exactly are you trying to accomplish with the total package?

 

For the cubes i will go for a 383ci.

Iam thinking about thoses cam XR280HR 242 248 @.050 .570 .576 of lift or XS282S 244 252 @.050 .520 .540 but this one with 1.6 rockers .554 .576 .

I alredy got a Edelbrock air gap vortec but i am thinking about selling all the vortec setup not sure yet...

The 383 will see a little street use...To make some "victimes"
But will be a second car.

My goal is to run mid to high 11s on motor (With pump gas) and some 10s on a 150HP nitrous shoot.

 

I havent really seen any solid performance numbers posted with e-tec heads. Anyone have any dyno/et's they want to post using the 200's.

 

357 RWHP @ 6100 RPMs
12.18 @ 110.86 1.68 60ft.

355
Mighty Demon 750
Air Gap
9.7 to 1 compression
Healthy Comp hydraulic roller cam
1 3/4 headers
3 into 2.5 inch X-pipe exhaust
This was in my street 79 Monte Carlo with a lockup 2004-R transmission, and 3.73 gears.

With 20/20 hindsight, I would have went back and put in some shims to bump the compression, and port matched the horrible head/intake mismatch. It would have run 11's, guaranteed.

12 MPG BTW

:edit: Theres an article called 530 HP from spare parts on Car Crafts website somewhere. I cant seem to find it right now to link it though. It was in the December of 2002 issue. They used a 355 shortblock, 11to1 or so, a big solid flat tappet, E-Tec 200 heads, and made 530 HP and some killer torque too.

 

Click video link in sig.

E-Tec 170 heads

 

I found this...

I would go Vic Jr with a healthy solid roller cam thats got some big lift numbers. Match it with a Edelbrock single plane.

Sounds like you need a trans, converter, and a rear axle to go with it all.

 

I agree, go single plane.

 

Open plenum should be bether with nitrous...

 

I have a 383 with AFR 210's that have a whole lotta work and a zzx tpis cam and a miniram. Worked nice. I am selling it now because I am going with a big block. I got a 350 with Trick Flow G1 heads that have a little bowl work and a little work on the intake side. Nothing much. Just a little cleanup. A LT4 hot cam TPIS big mouth base and ASM runners. Car runs strong. I dont know the full potential yet but I am going to the track this week before I install my HSR and rev kit.

 

I found the perfect setup (Super chevy danger mouse part 21 test 36)

-355 ci
-victor jr heads
-super victor intake
-comp cams XR286R solid roller cam (248-254@.050 .606"-.612" with 1.6 rockers

-455 ft-lb max TQ
-420 ft-lb avg TQ

-508 max HP
-365 avg HP

I will kept my nitrous shot...to...125-150 HP

:rockon:

 

I have AFR 210s (CNCd and then some) they are on a 400 + cubic in mini ramed motor and i have no complaints..
I went 11s on street tires and a trans that wouldn't go past 5,000rpm stock chip and 24 lb injs wee I'll be getting it sorted out soon though oh and mph was just under 120

 

I just buy a set of :hail: Victor jr pn:77599 for use with a solid roller cam (my choice is the XR286)they got a 64cc chamber with 2.08-1.6 valves 215 intake runers verry impressive . . I will post pic soon...

 

Where in Quebec are you Smokin?

Where did you buy your heads from.
I heard Zeke's in Montreal closed. And I haven't really heard of any other places. I'm near Cornwall, and buy most of my stuff from Total Race, who deals alot en Quebec.

 

I live in gatineau just beside Ottawa i can look to the parlement trough my windos I buy from my freind small buisness (G&G performance) We also have Consept autosport , Action performance , Canadian tire trough keystone , Evolution tuning...

 

Funny I've never seen your car. I'm in Ottawa every weekend for the meets, I've been to Luskville numerous times every season. There's actually quite a few of us around Ottawa(within 30min) with thirdgens.

 

This is me at luskville last summer !!! ive been there about 8 times in the summer.(Are you talking about Bank & Alta vitsta meet for the midnite street race?) I only noticed 1 fast 3 gen at luskville it was a red iroc-z with a intercoled supercharger 12.2s...

 

The cops have kicked everybody out at Bank and Altavista about a year ago, now everybody goes to Merivale and Meadowlands, near the Tim Hortons.

There was a real beater thirdgen running high 12's on a crap motor. Beat up 350 with ported 882 heads and V6 rear springs. i think he got rid of the car since. i haven't even seen the red Iroc your talking about. maybe it never comes out other than to play at the track.

Gotta love the left lane at Luskville. A 6" pothole at 100+mph is about as close to death as you want to be.

 

"Gotta love the left lane at Luskville. A 6" pothole at 100+mph is about as close to death as you want to be."

lol yes your are right about this

 

shop around, you can find AFR's for not much more than Etecs, but like you said, if you go vortec intake, then go Etecs. both are more than up to the task of making power. some minor porting to both will increase lots of cfm if you need more.

The trick flow heads 195's are cheaper than afr and i believe somewhere about the same as the Etecs. gotta check the catalogs on that one. but they flow just as good as AFR, again, some minor port work to get what you want out of it.

Pro Topline 200's are dang good heads for the price. they flow just as much as those others for less money. they like .600inch lift too for a big old solid roller. LOL http://www.protopline.com/123400000a.htm

 

He bought a set of Victor Jr. heads. A Damn good head

 

LMAO, woops, i missed it. i thought he was still lookin

 

etecs - get em bare and put yoru own valve train in them - the stuff they give ya isnt that great...

 

you can get the e techs for 1000 assembled from flatlander racing

 

Here is the super victor intake it looks like it will match the vic jr heads
