Can I get some opinion on this intale manifold running it on a 415 stroker ..but contemplating going on the a fast 102 ...has any one done the switch ...or is anyone running a pro flow with grsat results ..?

Theres a couple people on here that have. I've looked into it also. But if your not spinning it to the moon or its not a big bore stroked engine. Then its not worth it. Seeing ur putting it on a 415, i bet itll do pretty good. And most will say the fast isnt even worth it for the price.

I have seen too many people with sealing issues with the fast, I would go with the Pro Flow or one of the modular Holley's.

From what has been posted over on YB, the consensus seems to be in favor of the Holley with the Edelbrock running a close second. Fitment and the ports matching the heads as case seem to favor the Holley as well as them coming with the rails if I'm thinking correctly. I really want to see how they compare down low on a purpose built high compression mill with a cam spec'd to flatten out at 6500ish with good torque vs the NNBS intakes or an LS6. Longer runners are definitely a plus.

I agree ^^ ive been hearing good things about the pro flo on LS1 tech, but on here, the intake sucks on truck applications, supposedly.. id like to see some actual numbers

How often do you drive this truck? You will loose some down low with the hi ram or pro flow. There are lots of dyno sheets out there to prove it. But it will really shine above 4500. Just depends on what you want out of the truck.

Oakley6575...I have a question for you ...wont that low end loss be fixed or help by a converter ? I mean is that the reason we all get converters so we wont worry about out low Rpm ....speaking for my self since the truck has a loose 3800 circle d

Hell yea. I didn't know you had a loose 3800 stall. But still, you might notice some loss when you are daily driving it around. Cruising from stop light to stop light. But if this thing is going to be driven hard all the time, I would for sure go for the hi ram. What are you spinning it to?

Before I swapped the motor and turbo kit into my 01 GMC. I installed the Pro-Flo and an 01 ZO6 cam into my stock 168k mile longblock. With the cam and using the stock intake/tb compared to the Pro-Flo and Edelbrock 90mmtb there was a 14hp gain from 3900rpm up. Low end did suck, but it was a precursor test with a 168k mile longblock and stock exhaust. I really like the Edelbrock, but the Holley is more versatile with the interchangeable tops and porting ease. My Corvette is getting swapped to twin turbo and I'll probably try and use the Pro-Flo on it.
