Generation IV Internal Engine - ls3/l92 408ci hi ram intake vs fast ported 102

im just wondering has anyone had experience between the two?
the holley Hi Ram Intake with a Nick williams 102mm TB vs. Fast 102 ported
with a Nick Williams 102mm just wondering what peoples honest opinion is

im running TEA Stage 2 ls3/l92 heads 279cc 68cc
wiseco/eagle manley forged crank 11.5.1 comp
MS3 113LSA
Planning on a Direct Port 300on c16??

if anyones has any help lmk as i have a fast 102 but ls1/ls6 style im tryin to
sell and deciding after i sell it if i should do hi ram or buy another fast 102 ported for my 408??

What vehicle? The high ram seems to cater to higher rpm's. Also, you will not fit it under the stock hood on an f or y body, or the cowl. If your looking for good, all around useable power, stick with the fast.

2000 trans am i have a ram air hood or i have a v6 hood i can cut plan on reving to about 7k 6speed lq9 408 stroked with ls3/l92 cnc heads and a ms3

More than likely, your going to lose your wipers. I still say the fast will be a better intake.

thats what i was leaning towards but some people told me to look intoo the hi ram so i figured to ask on here

The hi-ram will destroy the fast everywhere over 5000rpm, and match it above 3500rpm, as well as shift the powerband 3-500rpm higher, and carry it 800rpm longer.

im shooting for 600+rwhp around 6500-7000rpm what will i gain powerwise with hi ram over the fast?

Is there a specific reason you want to use a MS3 on a 408?

I'd want a bigger cam then that especially with nitrous.

You need more cam and rpm to make 600 at the tire NA.

you gotta understand i chose the ms3 because i needed to be able to spray....itll make its power....:-) seen plenty above 600rwhp with a ms3

LOL, I don't mean to sound like an ass, but that is far from the cam I'd use in a 408 let alone a 408 on nitrous.

If you'd like I can spec you out one that will beat that cam up and down all through out the power band.

The MS3 is a fine cam in a 346, but does not have NEAR enough IVC or EVO for a 408 with nitrous.

I'm curious to find out the cam specs you'd think were good for this 408/n20? PM me the results if you would :)

I would never choose an ms3 for a stroker motor when there are so many other off the shelf stroker cams out there if you want to go that route.

Getting one spec'd for your combination is not much more than buying one off the shelf. So, If I were you I would get one spec's to maximize your combo and meet your goals.

forget the numbers really i just want to beat my buddys regal and he has a "junkyard setup" stock lq9 stock l92 heads tsp torquer v2 cam edelbrock victor jr x carb mani and a 850 carb on open dumps thats it with slicks runs mid 10's and on spray low 10's
and hes 580hp on that baby cam with stock shit so it is possible

580 maybe at the crank and that's a big maybe. That's not 580 at the wheels.

Listen to what we tell you and we can get you to run around your buddy like he's tied to a stump. Run the combo you posted and you will be "stumped" to why its not making power like it should.
