Anyone have experience with these? Thinking of running these on my still in planning 383 TBI. How will they do #'s wise? Also, can they be CA smog legal?

 

Well the 170's are supposed to outflow the stock vortecs by 30% maybe on the exhaust side. So the 200's should be well up there. For example, edelbrocks e-tec crate motor makes 435hp in a 350. I havent found out what their special cam is yet but I plan on it. Plus those are the 170's I think. I'm guessing their more of a high rpm power maker.

 

This shall be my first post, hey fellas. Umm, I have the ETEC200 heads on my 383 and I ran 12.43 @116 with only a dozen or so runs on my belt. This is in a #3500 race wieght camaro, manual transmission, bone stock wore out suspension, and 275/40/17 potenza tires with a 3.42 gear. A no nitrous no nonsense bad boy and I owe it too the Edelbrock ETEC200 heads. Well, that and my driving skills. I think if I did it again though Id get the 170s with fuel injection.

 

So this is with a carb, right...Disqualified ! !

Anyways, with the E-tecs, because they dont have an EGR crossover, your gonna have to plumb the exaust from your headers to your intake manifold, which has to have EGR provisions, and in this case must also be a vortec manifold.
Heres are pics of the SDPC kit that allows you to do this

thanks for the pics, makes a little more sense now. Are the e-tecs worth the $$ + the vortec manifold for the power they make, or are there better heads out there in a similar price range, keeping in mind this is a truck engine im building so tq is key but hp is good too, and i need to be cali smog legal

 

btw what valve covers are those in the pics showing the crossover? They look really good

 

I would not go with the 200's on a TBI vehicle. Your powerband and air flow criteria are better suited for the 170 heads.

 

already passed on the 200s figuring they were too big. If I do go with them I'll buy the 170s new. Is $1050 about the best I will find for them?

 

Why don't you try some Trick Flow heads?

 

any suggestions? fairly new too all this. Biggest thing at the moment is being California SMOG legal, good price doesnt hurt either though

 

It states on their site that the 23* heads are 50 state legal.

I have them on my 350 and they are awesome.

 

those look pretty nice, DD2K says 510 ft lbs and 375 hp w/ those on a 383 of my configuring, not to shabby. On the optimistic side, but still pretty nice numbers. Any other similar setups for less $$$, or is $1000-$1500 about what you will pay for nice alum heads?

 

That's about what you'll pay for good aftermarket aluminum heads. I would steer away from Vortec style heads if you have to keep it Cali legal, you'd have a hell of a time passing with that EGR situation.

 

Like ive said in many previous posts, we have plenty of people here in SoCal passing smog with vortecs with that very same setup in Kevin's pics.
The bigger problem here is having a 350 w/ a tbi. If you have a 350, yiu gotta go TPI or superram.

That being said, i would go with the trickflows rather than the vortecs.

 

I just think that's a lot of hassle that many people don't want to undertake. I don't live in Cal, so I couldn't really say anything first hand. Does it pass the visual with that setup? That's pretty cool then that it leaves Vortecs as an option for ya.

 

Honestly, out of all the people that have run that setup, no one has failed the visual.
But i agree with you in that its a bit of a hassle and i personally wouldnt choose that route. First off, your headers cant be ceramic coated before you weld on that bung. Second it limits your intake choices. Third, those trick flows are alumimum heads, and flow more than the vortecs.

 

so w/ the trick flows versus vortec or vortec style (IE E-Tec), what are my intake manifold options? Are there many, if any, performance TBI manifolds out there?
