Continue brother.......

 

All good mang.

 

Jake, what's the thought on going to a bigger bore down the line?

I've thought about the pros and cons of doing 4.125" bore vs 4.185" on my build... my smaller valved heads make me rethink the 4.185" bore. But with a sleeved block, it's free cubic inches. With the MMS heads, is he using a 2.200" or larger valve? Might be worth something. But I don't know what the trade off vs. flame front and timing and efficiency is with those larger bores to know whether it actually shows up on the dyno in any meaningful way.

 

Might have a decent comparison soon enough. Mine and 98ws6m6 both use Mamo heads. He is a 440 vs my 428. Similar cams. 256/270 vs 258/272. Both 4 inch stroke.

He has what tony called V1.5 heads. I have the V2 but then modified so not quite off the shelf. I expect similar power but torque edge to a a ron.

As to flame front I expect a fast burn. I will be surprised if peak power is more than 24 degrees timing. Either way it will be interesting.

As to valves his V1 was 2.20. V2 is 2.230 so a bit bigger valve.

If I had a sleeved engine block I would likely have gone straight to 4.185. Mine is stock production so I did not want to push it

 

I need you guys to figure out something on the intake. I'm sick of it. Cutting your own throat. Yeah Mamo figure this out

 

^^^very limited in fbody choices. My buddy has one with a 408, i cant believe how much they suck to work on!

 

As bulbous and huge as the front end is, the packaging is terrible.

A Vette is lower and sleeker and has more room above the motor and a larger oil pan. Think about that. Both the top and bottom of the F-Body LS is squished. Not to mention around the block on the sides...

 

ITB’s is the intake answer. Plenum volume is eliminated. Darth, you were dead set on ITB’s. Are you still considering them? I’d love to see what the setup is capable of on a 427+ engine.

 

mamo isn't a chasing numbers guy. he is a driveability and street machine guy. therefore the longer runner intakes fit his builds.

 

All BS ...why reference and say you've got 415 cfm then turn around and sell a ported intake that still cuts the person's throat. Added what in the hell is a Version 2 needed 4 and 99.9 % of his buyers are low profile street guys. He wants to do something contact or get a intake made so you can put 420 cfm to the piston. Anything other than that is BS.

Any and all other porters have a intake and head package. Other's use carb style intakes which can handle the 400+ cfm. He sells to you guys so he needs to figure out something...design a damn low profile intake to match his 420cfm v2 or v1 heads. FED,LME, CID, Mast,Dart, All Pro have intakes made for there head package that can provide what's seen from the heads. Although carb style. He caters to who...so he should do a intake ālso. Why would I even listen to someone who tells me he has a 420 cfm then say use my ported intake that flows 380 cfm. MF'er I lost 40 cfm f'ing with you. No nonsense Tolerance. I think most just like using the name and Dyno. My take on things and Mamo. Hell what he's doing we call a hand job. Bowls,SSR, v/j. Dude on YB has 410+ without the name and TFS ls7 heads.

 

He'd Really make some $.

 

Now that we have a new "LIKE" button, can we maybe get a "DISLIKE" one too?
Relax, your startn to get alil disrespectful and aggressive with your "BS" opinions. This aint a restaurant where you get it your way. You dont like the menu, keep it movin...I ve never bought a single Mamo part in my life, but i can appreciate the R&D he puts in constantly pushn boundries on improving things that do work for the masses, aka us low profile street guys. Why dont you finish your build/motor instead of armchair quarter backing everything n puttn people down who contribute to this community?

 

You should... it's all about options and choices. But what was said is a fact. Not a opinion. Figure if you like using the name while cutting your own throat have @ it. Again it's a system not just heads. The piston only knows what's provided. You had* 420 cfm. You guys know this yet Fail to want or ask for what you know. Darth is like my brother and I'd be damned if I don't say something. I want to see all what was seen on the flow bench @ the piston. 100 to 95% of the cfm is wanted. Free extra hp that's available. You paid 4 it. Why not get what you paid for. Must be a rich guys thing not getting what u paid 4. Figure it out ...they, he or whom ever needs to get it done. Without having to buy a 1 off custom intake and 1 that suits the needs of the low profile guys.

Sheet metal intake tested that can provide what's seen for a given rpm...then made into a polymer style intake for Mass production.

$ maker! From a dumb ***

 

I still do want one. Hammer did not seem to like his very much. Kinda made me question it

 

Fair enough. Im very aware of where you stand n I get it. No hate there.
Not every pitch in baseball has to be a FASTBALL to win the game!

 

I wonder if it was tuning issues? Or maybe needed more trial n error with other components? I was torn between the Harrop ITB and PD CF crossram for my build. I liked that they were both different in appearance. It was a tough choice, but Mike, my builder convinced me the CF crossram was gnarly n would get it done and look good doing it. Cant lie tho, the additional cost are snoballing, wait til you see what we trying to make work for the dual CAI...think lambo/ferrari CF intake lids

 

Me and Smokey been friends a couple years now. So if anyone reads his post and thinks he is hating he is not. He is helping. Just gotta know how to take his posts. I know where he is coming from and he is right. Most intakes do not allow the heads to shine. The whole thing from the throttle to the combustion chamber is a system.

In the 468 thread I remember the regular msd got walked by the lsxhr, but the Mamo ported one paced it all the way out. Out of the box the msd needs love. Also look at blackbirds intake work. Out the box msd was middle of the pack. Mamo ported outflowed everything.

I know a lot on here like to hate on hiossilver but he has been inside them also and found there is a ton of material to be removed to optimize that intake. Normally ported intakes are scuffed you and the seams are sanded smooth. These msd runners end up a good 1/8 inch bigger, or 3mm if you prefer.

Not saying it is ideal but I am saying that I think Tony HAS done a lot of work trying to get more out of his heads via intake, and for stock form factor right now, there is not likely a better option.

The heads will support Damn near 900 NA and I want to try to get all of it. Sometimes the power left on the table is in the cam too.

But anyway, please do not read Smokey and think he is ticking me off or hating or anything. We are cool.

 

Not hate....I want Everyone 1 to get what they paid for. 400+ seen ...well the piston wants to see it ālso, that simple. This is not rocket science. Those who win these challenges or races, just place what's seen to the Piston. Race thoughts used for the street or a DD .

 

Think about it guys. If we know more we got to ask 4 more. They're coming out with head after head. But Nothing to fully use them besides a carb style intake.

Speak up! Complain! Do something besides accepting the fact that I'm not getting 100% out of what I paid 4.

It's all Luv from me to us as the consumer.

 

You can't always have your cake and eat it too. Compromises are part of the game, especially when you want street manners and packaging that fits under a stock hood.
