Would love to even the field a bit by using Tony Mamo's ported MSD. Bet $$$ that on a 440 cube motor, the MSD would gain at least 25hp, which would put it at 740+hp
Comp Cams On the intake side, an MGZ 23502 lobe measures 250 degrees of duration at .050-inch of lift with a gross lift at the valve of .684 inch, with a 1.8:1 ratio rocker arm. For the exhaust lobe, an EHX-series 12701 lobe was chosen. It has 267 degrees of duration at .050-inch of lift. With .675 inch of valve lift. LSA unknown.
I was so excited to see this test and then so bummed that you didn't get Tony Mamo to Port the MSD. I think you would be surprised how much closer it is to those big intakes. My 427 made 807hp and 665lb/ft using his ported MSD
807 n 665 427??? Has to be a Borowski motor. I have no doubt its a strong build, but 807 n 665? What are cam specs? Hydraulic or solid roller? Lift? Compression? Fuel?
You want a broad torque band in a road race application. Ideally you would have a different runner length per cylinder to try and broaden the power band and a set of tri y headers to match.
@@AMac1978 so what intake is best I’m running a 2010 Camaro SS 6 speed manual and I’m about to install a GPI ported and rod modded intake with heads an cam already have a set of Stainless Works headers but not Tri -Ys are the requirement?
@@robertfoley6430 The cost of a FAST over the GPI ported and rod mod intake isn't worth it. Make sure you have a ported TB to match their intake and your headers are fine. You will see a nice increase in power and torque across the curve.
Helpful information, so thanks for posting! I’m building an LS 440 NA w/LS3 style Heads. I’ve been plucking daisies between the Atomic in the FAST 102. From what I reviewed, the FAST seems to be slightly more efficient. 🤷♂️ -not sure
Brule has got one hell of a Mullet goin on!
When are y'all gonna make more videos on the dual plenum intake
Love this testing!!! Thanks Mark!

Cam specs?
What were the cam specs?

What boost you got going on there ?
@@TampaDE5 naturally aspirated
@@FullForce1972 those are huge numbers for n/a
@@Velocitydrive Borowski Race Engines. My engine is a pump gas engine but they build killer stuff

I would still use the LSXR
LSXHR baby
So for a road racing application LS3 that runs 6500 Max I want a long runner intake??
Yes

Have you put it on the dyno? I have a similar set up
Go with tony mamo ported msd intake
They don't make the MSD Atomic for LS3 style heads.
Whats the mpg?
Msd coils sucks 👎got new one and acted funny . Stock works better
