Yup and it does. With the right supporting mods (heads and cam) a FAST will usually double the power gain over an LS6.

Will these heads gain 50% more hp than another ported LS3 head? If not, then what other perks do you get for paying more?

That's what I'm asking when presented with the statement "you get what you pay for". I wanna know what you get for the extra $500.

 

so your charging 1900 to port some heads. thats a hi price do you think. AI charges 900 I wanna say and WCCH is some where around 1200-1300.

 

The intake/exhaust cc's are a secret?? That is kind of a need to know detail when putting an engine combo together.

Also, do you have any dyno results?

 

"You send us your heads, We CNC/VJ/mill if needed/assemble with new .660 lift dual valve springs. Can do new stainless valves for an extra cost.

Stainless valves for intake and exhaust Add $450
Springs good to .700 lift Add $250"


Intake and exhaust port CC's arent a secret, they just never got poured. To be completely honest, we havent seen that much difference on the multiple previous programs we have tried as far as peak rpm and power go. Alot of real engine builders tend to use a larger head and dial it back with the cam anyway. Dyno results are coming within the next few weeks.

 

Would like to see some results on these heads.

 

^^^LMR is correct on this. The same work from AI is more than what you posted lilaaron. Still,......it is $1345.00 for the most expensive options from AI which is still $554.00 bucks cheaper and is a proven head.

I know this will be a great product from LMR and produce some stellar numbers when the dyno numbers come out, but on the down side if there isn't a good difference in separation from the other heads on the market it will just be preference in name when purchasing heads.

LMR, you have some stout competition out there in the LS3 rect. port world. I hope your price reflects what is to be had power gain wise. I think y'all probably already know that hence the higher price. Only time and a dyno test will tell. Good luck.

 

Updated original post.

 

Now I know that flow numbers aren't the end all in terms of performance...but for less money that just this 1500 dollar CNC job (without castings) you can get a CNC job that includes castings and flows better all around.

So I ask again...am I missing something here?

Sorry for being a doubter here, but I'm still trying to understand what the benefit of spending some $800 more for less potential?

 

You are correct when you say flow numbers arent everything. But then you contradict yourself later on by saying these have "Less Potential."

If that was the case, Take our ls7's for example. They flow under what alot of other peoples programs do, but yet made over 10 more RWHP than the other programs we have used in the past (With better flow numbers.) They actually made within 5rwhp of a well known aftermarket casting ls7 headed and fast 102/102 build did but through the stock intake manifold and throttle body!

And this is stuff we have seen with our own eyes on our own dyno. Not something we read on the internet somewhere.

 

They look good.....any dyno numbers yet?

 

Holy hell! $1500 to port customer supplyed heads! Thats rediculous! I can get tsp to port for $900! Advanced induction got therebudget port for $795!! I was realy hoping yall would atleast beat everyones elses prices! I just want my heads cncd and valve job no milling,how much?

 

I wonder are you guys at LMR re-thinking your sponsoring of this board yet ? LOL
waste of $$ (the sponsorship that is, not the heads)

 

^^^are you kidding me?! Your an idiot to think that!

 

CNC/Valve Job and re assemble your looking at $1450

 

Thanks!

 

LOL. I like for thinking

So............. has it been a few weeks yet? Peek numbers are all, but how are the numbers under the curve/peek?

I hope you didn't pay AI all that much to design and digitize these, because at these prices, only loyal customers will be buying them. IMHO.

 

Ai or was it Greg Good? I heard different rumors. We all know, they couldn't put it on the internet if it wasn't true!!!!!!!

 

Was neither AI nor Greg good. Rumors are exactly that, rumors.

Still no dyno numbers on them as of this exact moment. Also we did not pay AI anything for anything. They have nothing to do with any of our cnc programs.

 

If you end up wanting comaprative data to other heads and want to test yours in a track situation, I'll be glad to test them for you. I have a set of Stock LS3 heads and GMPP Ported LS3's I will be testing in the next few weeks on my car. It's a 408 carburated application in a track only drag car.

 

Then stop the rumors and tell us who did the heads?
