I find myself agreeing with you too many times today.. I'm honestly a little scared.

 

Sean,

A 355 can easily make 10ft lbs more TQ since you can tweak so many little things to get that for you that you can't in a stock bottom end. When I'm talking about that TQ range it's about the stock cube cars, not strokers. All you have to do is look around to notice that the strokers are much higher than that.

cmroSS97 "i think the last bre/le 383 car made about 428 rwtq.......fwiw"

Same here.

I love how I get you guys all rilled up. If you didn't really reguard me as something to care about you wouldn't even care..... lol

 

wow...this is crazy...My cam is at least a 8 year old off the shelf grind..anyone up to sending me a new one? The only "custom" part of my cam is I told them to put it on a 110 instead of a 106...I wanted it to be a street car back then..lol.

Joe..nice to see ya around.

As far as the heads go, I've seen good results out of both camps. I'm not sure if LE has had anyone go full out on his setup but I know of one that is close. In a car that is Set up for nitrous he is prolly going to bust into the 10s soon. Runs 9s on the jug right now. I'm not sure what cam he has but I think its a 306...could be wrong though. As stated elsewhere here a cnc is a good way to put out a consistant head. I don't think it will be a max effort head though. Look at any of the really good performing cars out there(above your average guy with same setup) and you will see a set of hand finished heads. I know some people will start with a set of cncs just to knock off alot of the meat off then go in and hand finish the setup. I've also seen cnc heads that are all over the board on port to port flow..so don't think they are all perfect. But..same goes for hand done heads..I've seen ports vary as much as 30 cfm. I agree with LE though in that if your looking for a good running car you will be satisfied with heads from either shop. .

 

Sup Tim?

 

not much...just rebuilding my pump gas bottom end. Its only 5 years old at 7000+ rpms...thought I would go in and check it out before something lets go and hurts my heads.

 

I should be scared? Or I should be agreeing?

 

Brett the rock is a life...maybe you should find one, other than the internet .

And Brett please, as far as a conversation. Why would I give you any more knowledge than the cam guru you self proclaim to be ,wouldnt already know.. wheres this power across the curve? on a peice of paper? cause thats the only place maybe you can show me.But as the people with some dyno knowledge know, things can be made to seem what they really are not.. Other than that why dont you step up and really and I mean really do something... I don't have 1 car or 2 cars I have many ,and suprise!!!! I didnt tune all of them or set the cars up...But alas they outperform your best efforts...

All we hear is dyno this, dyno that... when it comes to you...

So anybody reading this....here is some wise information..

If you want to be a sheep grazing in Brett's pasteur and all you want is a dyno graph to show your friends... by all means you found your boy in Brett..

If you want to hold a timeslip to be proud of instead of a dyno sheet...well need I say more...

............
now lets start hearing the crying of excuses..

its tuning, its car setup, its blah blah blah... You had a few years Brett you cant tell me you havnt had quite a few of what you thought would be top performing customers... Maybe a search would show how some of these power houses failed to meet expectations... only to hear the same backing up of excuses we'll see you post here... Happy Sales Brett .. If the Moderators remember years back I got slammed for advertisement...thing is I never pushed anything, Unlike you.. figure with all your cam sales you could atleast kick back some revenue to a board you utilize so much ,and thats enabled you to make some income. I mean what is good for the goose is good for the gander as it were...

 

FWIW to the rest of the guys eating popcorn reading this thread... sorry for getting off on tangents and arguing. I had a family member die this weekend and I usually fall of my rocker and start fights with the kids when crap like this happens.... I just have some strong thoughts that most times I keep to myself except when I need to do a little "venting"

Mature as normal Overton, Back to the name calling and acting like a punk as normal I see..... at least learn to spell my name correctly.

Still nothing technical to talk about as normal. I wouldn't want people to know I was "slow" either if I was you.

On a full out set of hand finished heads(not the LE1, LE2,..maybe some LE3) I would tend to give the nod to them over a set of cnc heads with no hand finishing. I want to qualify this by saying I've never had my handson a set of either heads(LE or AI). If the cnc head outperforms(I'm not talking about flow bench crap) the hand ported heads in a apples to apples compairison then they have a better port design. But I also believe that that cnc port could be made better by some hand finishing.

 

trymy6: This always happens. I will give you some relavent info, but then I will add to the pile.

I bought a cam & head package from AI. I got the 190 CC heads, and a gm-847ish cam (within a couple of degrees). I have a 96 SS, 6-speed, bmr suspension parts (lca's, sfc's, torque arm, k-member) and moser 12 bolt.
It dyno'd 397.3 rwhp & 357.1 tq N/A.
Here is a vid of a pass I made:

http://videos.camaroz28.com/search/9...904A07731B.htm

At the time of the video the car weighed a little over 3800, w/me in it.
I bogged it out of the hole (as seen in the vid, there is a sudden jump then it falls flat, then picks up). I should of gave it more RPM, might of gone a little better, but that's how it was.

I put a 200 shot to it and it dynoed 575 rwhp & 614 tq.
That got a 10.5 @128, but the clutch was slipping all day. It managed to hold together for that pass, but ultimately was inadaquate (spec stg III, aluminum FW). You can hear it in this vid:

I am tweaking things a little more and will have my new set up out shortly.

I have no information on LE products.

I am making an effort to get a bunch of guys to get together and race

http://web.camaross.com/forums/showthread.php?t=448220

Why does every one want to race dyno's and not cars .
My car didn't break 400 to the tire but it runs in the 11's and has a respectable trap @ almost 117. So on the dyno (or web, or engine analyzer) I loose, but on the street I run good soooo that doesn't count?

This debate is getting some what tiresome.

Lets take it to the track.

 

Because dynos eliminate variables, like a sticky tire, gears, weight, driver error, suspension setups, etc. Atleast with a dyno you see the differene in curves, one may be peaky while the other is broader. Its easy to tell which car would be faster with both cars having everything the same except heads/cam package just by looking at dyno curves.

 

I'm not taking sides on this becase I don't care either way...but LE has offered up a set of heads for a test..I haven't seen AI offer that. I do think if this is done an existing set of heads..say within the last 3-6 months should be used to get a true judge of what each shop is putting out and not give them a chance to "prep" a set of heads.

 

Good point.
