- I'm resisting for now. I gotta get a car 1st lol. Life's priorities 1st. But I will be in contact when the time comes. Been lurking since 2020. Intaking everyone's threads,etc. I realize there's a ton of reputable shops and companies. Don't see Mamo mentioned alot other than everyone and their brother uses his ported intakes but what I do see of him, it's always positive and praises. I like the fact he uses what he does.

Actually I have a really nice 24" roller SuperFlow with an 800 HP Eddy brake / load cell.....its under a tarp at the moment but hoping 2023 is the year we finally break ground on the install!!

Sad to see all the sniping and BS. Can't we all get along? We're all here-hopefully-for common good of our cars, and educating each other, not name calling and personal insults. Sheesh...

hmm. so many heads, so many opinions. that is what is hard to wade through. i kinda feel like i could put a bunch of companies names in a hat and pull one out and be just fine. i definitely want a nicely ported head. i've heard good things about mamo, trick flow, ai, american heritage, and i forget the name of others. sounds like a bunch of subtleties between different companies porting and maybe geometry if an aftermarket casting. part of me thinks an aftermarket casting may be better as you can maybe avoid some of the flaws gm has with the heads. but, i hear really good things about companies that port the stock heads.
Throughout all the research I have done in trying to determine which heads cam package would suit my needs best. I had taken my time and really studied dyno charts. I'm not worried about what the numbers "are" or "aren't" instead I began looking at Torque and HP curves. I didn't make my decision hastily, and it took me an entire 2 years of reviews, calls, research to reach my deciding point.
If you look at the dyno graphs below.
This graph was from last year in April. As the tune got better so did the numbers. Also looking at the torque curve; the car makes around 300 ft-lb almost instantly 2200 rpm it and remains flat well passed peak and gradually falls off. The HP comes in smooth and Carrie's all the way to top end. This engine was still making power with no signs of the curve falling off when they let off @ 6900 rpm.
This car from this dyno graph is my good friends Z06 he too is running the RAMAIR SS CAI. He just got tuned within this month. More like one and a half weeks ago. Both of these cars are almost 1 year apart. And if you look at the torque curve you will see torque begins building immediately and flattens off gradually towards top end which is a VERY common trait with Tony MAMO's heads cam packages.
In comparison to many other companies this is something that drew my attention.
They are two different cars, that are in two different time zones. Almost 1 year apart Tuned by two different tuners on two different dyno's, but the sexiness in the torque curve and how smooth the power comes to life. Not to mention how it carries though-out the power band is really what got my attention.
You can clearly see how well set up and thought out these heads cam packages that Tony designs truly are.
That is why I decided to go with MAMO MOTORSPORTS MMS and their 265cc stage 1 heads over all other manufacturers out there.
In comparison, below don't look at the numbers. Look at the torque curve differences from above 👆 and below 👇 and the way the power comes to life.
The first graph shows the difference between the old heads/cai and new heads/cai, the 2nd graph is the difference between the old cam/balancer and the new cam/balancer.
539whp: stock heads, mamo msd, nw103, arh 1-7/8 headers, corsa intake, hsa s3.7 cam(supposed to be btr stg 3 equivalent)
551whp: added AHP Archangel heads(66cc) and ramairss intake
567whp: added btr stg 4 v2 and 10% ud balancer
Again we are not talking about dyno numbers here... just the power curves.

So, I see many on here that dump 20k in a stage 4 or radical HCI , making 620-650rwhp and its still stock bottom end ls7.
I wasn't aware if I dropped the car off at AHP , theyed charge me 10-12k to perform a engine swap and tune. I assume a clutch install would run 3-4k give or take , providing I didn't pick the more expensive options out there. Maybe a monster ,etc.... regardless , you didn't mention how much the average ls7 went for so I'll again assume 10k. Now, I'm looking at 5-8k over a HCI package. That's figuring 25k for a turnkey stroker.

Let me put it into perspective, a 600 whp Z06 will leave an 800 whp just about anything else.
A stock Z06 will walk a 600cc crotch rocket.
A Full HCI car will walk a 1000cc crotch rocket.
On a stock bottom end.
When these cars get out of control it is a violent out of control situation that happens in the blink of an eye.
I am sure you want to go to a 440 cu in displacement. It sounds like fun and all, until it scares the living hell out of you and points itself at a Gaurd rail at 120 mph +.

Hahaha you spying on me??? You mean drive with Nannies engaged?
I ride motorcycles, and traction control is all in the right wrist. I have owned several crotch rockets over the years, I have owned a couple CBR 1000rr's, zx6r, zx10r, R1 and Hayabusa which I did a top gear pull on several times. It has seen over 220mph on the speedo.
Personally I like the way the car feels without Nannies engaged.
And I have changed my driving habits ...the car learned me something good.
nothing like an ohh **** moment where your ******* squeezes so tight you can make a Diamond to keep you from doing that again LOL

One of our turn key ready Forged LS7s can range from around $15k-$30k depending on the parts used and if we are reworking some of your parts or going with all new parts. With that said we do give core credit for alot of parts when going with all new parts for our engine builds.
Here is a link if you want to check out pricing and options:

of course you can always send me an email hp@americanheritageperformance.com to discuss anything you dont see or any questions you might have.
This is not an accurate statement at all.
A properly calibrated Hub dyno will read the same as a properly calibrated rear wheel dyno when all other factors are the same. Plus there are a ton of dyno sheets out there of our products on cars from all over the world on tons of different dynos not just on the dyno's we use. If you want to start picking on dyno numbers I would start with the incorrect correction factor a lot of guys that post chassis dyno graphs online use. All Chassis dyno graphs should be posted using the industry standard for chassis dynos which is SAE J1349 (2004) correction factor, this is going to be the correction factor that generates the lowest numbers. Any other correction factor being used when posting a Chassis dyno graph is artificially inflating the numbers.

I don't like to feel like a computer is driving my car instead of me. I hate how the car reacts with all the nannies on if it gets just a little sideways. If it's raining or something, I leave them on but otherwise I'm usually in comp mode.

I never turn it off. I actually wish the traction control were quicker to respond (needs a faster thinking brain I think...like me before coffee) and just a little more aggressive when doing so. If I roll into the power in 2nd the traction control seems to allow the TC to keep up with things as the traction breaks loose and I can ride the hazing all the way through to redline. That's in 2nd. There is no hope for 1st gear traction any longer. I'd love to be able to really hammer it in 1st and 2nd and let the TC handle things....but it's not programmed for this kind of power. Gonna need a Motec or similar for that.

As for the matcho men that drive without traction control - that’s the reason for so many crashes and unnecessary injuries to yourself / innocent others that got in the way. Put the testosterone boosters down. Word of advice - if you get into a new supercar don’t touch the traction control or you will be in a ditch real quick.

Agreed I wish it was more accurate like the Porsche / Mclaren / supercar world. Granted their systems are probably more costly than the value of our cars but it sure would be amazing.
