383 240z Posted February 15, 2004 Share Posted February 15, 2004 Any idea how these compare to the AFR 190's You recommended these heads for my engine a while back, and I've been saving my nickels and dimes, but with new information you somtimes have to make new decisions. Plus I get Wholesale pricing from GM!!! Keith Quote Link to comment Share on other sites More sharing options...
Guest Nic-Rebel450CA Posted February 15, 2004 Share Posted February 15, 2004 Nice Any noteable differences to the 206's vs the fastburn heads other than flow? Quote Link to comment Share on other sites More sharing options...
strotter Posted February 15, 2004 Share Posted February 15, 2004 You know, I have mixed feelings about Chevy coming out with all these cool performance parts and motors. I mean, it's cool that they make the parts and all, and it saves everybody a bunch of money and time (especially the performance crate motors), but I feel like it's kind of stepping on the toes of all the motorheads who have burned zillions of hours learning all the tricks and doing all the research. I don't know how many times I've seen (or heard) a great motor and struck up a conversation with somebody about the work they've done on their car. Just a couple of weeks ago I spent an hour talking to a guy with a blown smallblock pickup in the Pep Boys parking lot. We both had an excellent time. With all the new stuff available from GM Performance, the conversation might have gone like this instead: Me: Wow, that thing sounds sweet! What is it? Him: It's a 383. 425 hp. Me: Cool! What cam is it? What heads? Did you port-match them? And hey, what manifold is that? What's the compression ratio? I mean, dynamic? Him: Uh, I dunno any of that stuff. I bought it from Chevy. It's a crate motor. Me: Oh. Okay. Nice talking to you... I dunno, maybe every time you gain something, you lose something too. Sigh. Quote Link to comment Share on other sites More sharing options...
Guest Hauptmann03 Posted February 19, 2004 Share Posted February 19, 2004 Hey All, I think it is going to put more funin the "street scene"so to speak. It will make more equipment available to more people and better equipment to excite the public and racers. Perhaps your conversation would have been more like this: Hey man, I like your machine! It looks and sounds great!What yu runnin? Man, I put together a real package but I had to do a lot of research. You know, those crate engines are not so simple. I looked at about 5 magazines like Super Chevy, Chevy Rumble, Muscle Car Review, CarCraft, Super Rod, GM High-Tech Performance, Mustangs and Fast Fords, Tech Guide, Engines (Mail Order Engine Guide), High Performance Crate Motor Buyers Guide, and a bunch of Road Racer type mags to get comparisons. Then I was more informed and with this background, I think I can add the touches I need to be competitive! Yea but they all seem the same and everybody knows what ya got. Not really cause it takes a lot of work putting together gears, trannies, tires, tuning, and then weight tricks, and suspensionis anotther gig! Man,I haven't even got there yet! I gotta go work on that! Later! Quote Link to comment Share on other sites More sharing options...
383 240z Posted February 29, 2004 Share Posted February 29, 2004 I called my GM parts warehouse, and they tell me that the part number for those new heads is not a valid number.

Guest crazymike Posted March 17, 2004 Share Posted March 17, 2004 true all of these awsome new stuff comming out allows less-knowledged people to have cheap fast power, but it also works for our gearheaded advantage. Everytime I find out about a new inexpensive performance part I find myself dreaming about an engine build that is just as cheap as before, but makes way more power. Let those who don't want to learn stay less-knowledged, but when they pull up next to a machine built by someone who knows excactly what to buy and what not, they'll still get smoked. the faster they go, the faster we go. Its just thier Idea of fast is not nearly as fast as our ideas of fast. Quote Link to comment Share on other sites More sharing options...
383 240z Posted April 16, 2004 Share Posted April 16, 2004 I talked to my GM supplier today. The posted price on the 206cc version is $335 each (he could not tell me if that was bare or assembled) with no date yet on release has anybody else looked into these or have any new info on them? I'm guessing that when these are released the magazines will have a feild day with them hopfully driving DOWN the prices of the older units at the swap meets.

Guest 77vegasz Posted April 16, 2004 Share Posted April 16, 2004 The thing that gets me is the fact that alot of this stuff is coming out AFTER I spent a ton of money making mistakes and learning. I have spent way too much on a motor that does not compare to this one! Oh well, it was a fun ride getting here. Jon Quote Link to comment Share on other sites More sharing options...
