hey i hope im putting this in the right spot. I was just courious if the edelbrock e-tec heads will fit up to the TPI intake
thanks,
john

 

no, youll need a vortec base to make it work.

 

our these heads suppose to make more power then the rpm performers?

 

well i personaly dont know, but for a guess. i would say they have the same intake runner features, but the combustion chamber is suposed to be way better than the basic rpm head. so i would assume that they are better, but not by a huge amount. there supossed to flow better than the GM fastburn heads (which is a good head). i would think that getting the edl. e-tec head and the TPI vortec base would make a solid foundation for hp. i was thinking of do that myself.

 

thanks guys but im kinda confused i thought the stock tpi had the vortec base. So the e-tec heads wont fit on a stock tpi intake?

 

nope, stock TPI as a standard intake. the vortec's have raised runners.

 

this isn't making sense...a set of e-tecs(assembled) cost ~1100$, while a set of GM vortecs(assembled), already worked over for high lift would cost less than 800$?

the only thing i see the e-tecs have over a pair of worked vortecs is the 200cc intake runner option.

seems to me you're paying an extra 300 dollars for the name.

and 30lbs less plus they do flow better than the GM vortec's.


oh wow, i just saw the price of the edl. vortec base 451.99. and the TPI Vortec Lower Intake Baseplate :: 12498060 - SDPC is for 400. just in case any of you were wanting to switch.

 

so are you compareing the newest top of the line vortecs to the e tecs?

 

lol this is getting kinda interesting,i appreciate all the feed back well ok what heads should i use im not looking to rev the engine above 6300rpm cause im not going to replace the internals this winter ware could i find some information about the gm vortecs tobias is talkn about
once again guys thanks for the feedback

 

i didnt know of any new vortecs, please educate me. do they flow better, better lift out of the box? cool i did know they had new ones.

 

well, i mean not new like yestureday. im looking at the heads in the jegs mag, they have the large port vortec heads, then there are the alumiminum vortec heads 809-12464298, i was compareing the etcs to these two heads about which one makes the most street power, about 9.5 10 comp

 

well im not saying that the heads have to be vortecs im just looking for a decent set of heads that i can bolt up to my tpi intake

 

i was comparing early style vortecs (not bowties), with high lift modifications, against the e-tecs.

...e-tecs aluminum?

 

oh ok, i wanted to buy a new set of heads, and im really interested in the etec's, but then i read up on the bowties too. are they just reworked old vortecs? i know the vortecs can make really good power too. maybe somebody has used the new heads that know more about it.

 

so are you just sayn to get the stock heads completely workd over and they would be pretty decent?

 

IMO, yes. unless you want to step up to the e-tec 200cc runner and an aluminum head for another 300 bucks.

but is running a vortec style head for a tpi setup worth the extra spent on the vortec specific base? tack on another 400 bucks... you could almost buy a set of afr's...

 

, but youll still have the restrictive base. and unless youre running a 383 on up i dont think that the 200s or nessesary.

 

First, we dont need to see huge sig pics with every post. Once per thread is fine.

Second, my dad has the Etec 200 heads and Scoggin Dickey Vortec TPI intake. He was one of the first to get one. It has made 322 HP and 394 TQ at the rear wheels with a ZZ9 cam, 1 3/4" SLP headers, 3" Magnaflow exhaust and a T56 tranny. The runners are siamesed SLP's. Its run a best of 12.80 @ 106 MPH at a 3000' track. The previous best with iron GM Vortec heads was 13.02 @ 103 at the same track. I think its output was 302 HP and 366 TQ.
Edelbrock makes the Vortec TPI intake for Scoggin Dickey, so definitely buy one from SD and save some money.

 

So would you say your pleased with the results from the 200s? I have been debating on either going with them or dumping my intake and getting new afr 195s (already set up for vortec) also a few more questions how did they look out of the box was the valve-train hardware any good

Ive been trying to find solid info on thoes heads for a long time and its a pita for some reason any thing you know is helpful

AL

 

Kevin91z, was that a stock 350 motor with the etc's ur talking about?

 

Well, I dont consider an engine with heads, cam, siamesed intake, and headers to be stock, but if you do, then ok....

Did you mean if it was the stock bore? No, its a 355.

 

ok, yeah thats what i was looking for.

 

has anybody seen the "something old something new" article in GM hightech performance? it is a 355 with vortec heads and accel high flow tpi.
it put down 416 hp and 487 ft/lb on an engine dyno. and it made peak power at 5400rpms.

i am personally tryin to build the exact same motor for my car, but i was looking at the e-tecs as well. with better flow rates and alot less weight i think the $300 is worth it. ive also beeen lookin at the trickflows which are comparebly priced

 

The Etec 170s make significantly more power than any other Vortec-style design, including the Bowties. If you go back in Super Chevy's Danger Mouse series, they named the Etec 170s the best combination they ever tested, with over 450 hp, over 480lb/ft torque, and an amazing torque curve. They later tested the Etec 200s, which did make more peak hp, but less power between 3000 and 5000 rpm, and less torque as well.

Recently, AFR came out with their Eliminator series, which adapt LS1 design to standard small blocks. They perform even better than the Etec 170s, and use standard intakes. I'm buying a set of the 180cc Eliminators. For a stree engine under 400c.i., runners larger than that hurt more than they help.

 

i had a set of cast iron vortec heads on my 383 tpi iroc.i used the scdp vortec base at first and made 289 hp and 365 ib's of torque. then when the hsr intake for vortec heads came out i got one and made 317 hp 367 lb's of torque. Later when i got bored i bought the etec 200 heads and a bigger cam and made 396 hp and 412 ib's of torque and went 11.98 @ 111mph with 1 5/8 headers, 3 in exhaust, 58mm tb, t56 tranny/w spec stage 5 clutch and 3.73 posi on 255/50/16 drag radials. THE ETEC(200) HEADS are worth every penny. but no matter what head you use the stock style tpi setup can't make much over 300 horse to my knowledge. But if anyone wants the scoggin-dickey intake base i would sell it for whatever half its worth new.
