Fast 102 Race Runners vs. Ported MSD - LS7 Good Morning
Was just looking at Fast’s race runners and they look like they will definitely add more power the bigger the engine like my 454. I already have the Fast 102 with regular runners.
I’ve also been thinking about Mamo’s ported MSD and how it would fair against a Fast 102 with race runners on my 454.
Or would an ITB or sheet metal be better for my setup?
I’m keeping it NA.
I’ve heard mix reviews on ITBs. Some people gained yet others reported similar gains to those with Fast 102s and MSDs.
I’m actually lost at this point and need to squeeze the most HP out of my setup.
Any input is appreciated.

Your very limited as to what you can do with your low hood. I’m sure you’ve seen, over on Corvette Forum, what those guys are chasing with their big engines. Plenum volume is key to feeding these engines. The best current front feeding, single Tb intake for an ls7 with extra cubic inches is the ported MSD, and Tony is king. At this point, if I were you, I’d call Tony direct. He’s spent the last 3 years working with his LS7 program, and in fact he’s already found new stuff since I bought my top end from him. My heads are going back to him this spring. Nobody out there has put more research into the LS7 package. He will shoot you straight, and has the best customer service in the industry. If your serious, he’s your answer.
Hes a busy boy. Leave a message and he will hit you back.

If cost is no object I'd call Marcella for a sheet metal intake or an ITB manufacture and talk about your goals. Otherwise the MSD is the best compact composite LS7 intake on the market currently.
If you arent planning on moonRPM and its a street motor the MSD will be fine.

I have built countless 625 - 660 RWHP OEM 427 builds utilizing this intake and a 700 RWHP 454 as well.
Also FAST does not offer a race runner for the LS7.....only the LS3 and you give up a bunch of bottom and midrange power when you move into those shorter runner lengths.....there is no free lunch IMO with the exception of a properly modified MSD.
I have guys picking up 40 - 45 RWHP over a stock intake in more aggressive applications.....those are numbers usually associated with a head swap not a manifold swap
There are a bunch of threads (independent build and dyno threads) concerning my ported MSD intake (Google Mamo ported MSD), but here is one that you should check out of you haven't seen it already
https://www.corvetteforum.com/forums...t-mamo-vs.html
The MSD fattens the curve everywhere and I tell people works better than it should even up top for a manifold design that works so well at the bottom and middle of the curve as well....its as close to the "Have your cake and eat it too scenario" as it gets and I have dyno tested more manifolds in the last 20 years than I can remember.
Feel free to email or call me if you would like more information or would like to place an order.
Cheers,
Tony

Anything worth doing is worth doing well. Build it right the first time....its alot cheaper than building it twice!!

My ported MSD for the LS7 is as proven a piece as it gets and has trounced some expensive $3500 billet / sheetmetal intakes as well.....its really a very difficult manifold to beat unless your building an 8500 RPM true drag race application and buy a purpose built custom intake for that application.

Restrictive at high RPM. If you are planning on spinning past 7000ish youll see more power with a different style intake than a compact composite is what he is saying.
If cost is no object I'd call Marcella for a sheet metal intake or an ITB manufacture and talk about your goals. Otherwise the MSD is the best compact composite LS7 intake on the market currently.
If you arent planning on moonRPM and its a street motor the MSD will be fine.

Yes, the majority have been saying the same thing. But when I talked to a guy who actually has the Harrop ITB with a box setup to pull air from the front of the engine / on top of the radiator, he said that if Iwere going to a max RPM of 6500 then the ITB will be more beneficial since it produces peak HP at around there. And that if I wanted to rev higher then a Fast or MSD would be more suited for my application.
I’m absolutely torn at this point and should probably listen to what Tony has to say.

If it produces peak tq at that rpm it's not peak hp unless it fell of very hard which it wouldn't. Tony is very smart & will point you in right direction.
