Pick an intake for a street driven 410 stroker - Poll inside
 

What intake should I go with? I want to keep the RPM's down to a dependable level, and the cam will be custom ground to compliment the 3.73 gears I have and whatever intake I come up with. I'm trying to decide between the Trick Flow 5.8 version, The Victor 5.8, and the Holley SysteMax (if they have this for the 5.8 yet).

Edelbrock claims the Victor 5.8 has a range of 4000-7500 RPMs.

The Trick Flow 5.8 intake I believe has a range from 2500-7000. I can't really remember and Trick Flow doesn't offer this info on their web site, but I am pretty sure it was a tad lower range than the Victor 5.8.

The Holley Systemax claims to be between 2000-6500 RPMs for their 5.0 version.

I'm leaning towards the Victor 5.8.
What do you think?

aren't most of those intake made for the 351 displacement engine?? your gonna be 57 inches bigger therefore pulling the r.p.m range down. how high do you want to turn it??

I never thought of it that way. Good call.

I don't want to turn it higher than 6500 at the most. This engine has to be dependable because I will more than likely not be able to leave it at home unless there is bad weather. This car is definitely going to be fun to drive :D

What "other" intakes could I benefit from?

Holley doenst have a 5.8 manifold, so you can eliminate them.

I still like the performer 5.8 lower with the performer rpm upper for a mid range RPM , reliable, daily driven tourqe monster.

The victor seems to be more for track use than street use. Its RPM range doesnt start until 4000! Might be a little high for a street car.

I don't know how sporty this is, but it could be cheep. My Bronco has a dual, looks to be a 35mm(don't quote me) air intake upper, with nice lower intake. It's for a 5.8. Like I said, don't know how good it would be, but it might work, plus it would be a lot cheeper. Go find it at a junk yard. I've looked at the same thing on the '89 mustangs, and mine looks a lot bigger.

Mach 1, I called my engine builder about intakes the other day and ran the post lx mike made in this topic about those intakes having an RPM range based on a 351ci engine. I asked him if he thought that a 410ci would lower that RPM range down much. He said it would.

Plus, I was thinking since I will have a tall enough hood I can always go with an intake spacer if needed. We'll have it on the dyno for awhile so if it looks like the peak HP is too high in the RPM range I'll try a spacer to see what that does. I'm sure with a little tweaking we can get the peak RPM range of 6500 to work good with the Victor intake.

Oh yeah, I've been in contact with Edelbrock too just to get their thoughts on this. I just sent them the new buildup info which changed a little from the initial email I sent them. We'll see what they say.

I apologize, my edelbrock catalog is outdated, and I wasnt informed as to the new 5.8 intake. I think your on the right track, good luck.

Oh yeah. Mach 1, that may be a good idea you have there with using the Performer RPM upper.

I know it's silly, but my brother has the Victor 5.0 on his car using stock ported E7 heads. He has no low end at all even with 4.30:1 gears, but the car is very streetable and runs 12's with a 125hp shot. He definately needs some heads, but it's working for him somewhat. Yeah, something other than the Victor would work better, but he got the intake for a steel and has plans on running 9's eventually.

lol..no low end at all and very streetable sounds a little contradictory.

Well that depends on how you drive I would guess. It takes like a stock Mustang, but once you hit mid range it has a lot of power.

I don't know how the 5.8 compares to the Victor 5.0 but I can say that I make lots of low end toque. Take a look at my dyno sheet.

Holy Crap!!!525lb-ft at 2800!!!! That is N/A????? with a good set of TFS TW I see Nice CFM on it BUT WOW 525!!!!!

If you take a look at this chart you will see where my engine peaked at just over 530 pounds of torque.

Not too bad for a 9.9:a compression ratio, n/a engine. But my hp is not very good. Torque is what gets me that 1.394 60' though!

what intake are u running?

All that power with a 347?? Not bad at all.

And your peak HP comes in at 5800 RPM while the torque is at 2800. That's what I am shooting for. Gimme power down low to get off the line without the need to rev it to the moon to reach peak HP and that should make for one mean @ss street car.

Mach 1, he's using a ported Victor 5.0 which does have a bit lower RPM range than the Victor 5.8, but I think with the added cubes I'll need to fill I'll be running one of the best intakes I could pick for my combo.

I was considering a Box upper atop a Victor lower. I could make a box at work, but figuring out the plenum volume and runner length would be a pain.

Victor 5.0 ported by me. The one that everybody says doesn't make torque below 4000 rpm. Haha!

8850 - Your HP does look a bit low for making that much torque down low. I'd hope to have quite a bit more HP than that with all the money I am pouring into this thing.

The votes are tied for the Victor 5.8, the Trick Flow R, and "Other", but nobody except Mach 1 has mentioned any "Other" intakes to consider. Come on guys, gimme some ideas here.

Oh yeah, mustangman65_79 mentioned the truck lower. Rick 91GT said he found a truck lower that will work with the Holley upper. Maybe that's the one mustangman65_79 is referring to. That brings the Holley back into the running.

What year do I look for to find this intake?

Thanks.

I was thinking of using the Super Spyder. I have seen it advertised in a couple of magazines but I dont remember who. It is basically a converted carb manifold. I am trying for a 427 NA for my 95. Let me know what you find out.

Greg

MMMMMM...... am I not a person...............I thought the Spyder is what I talk to you about..........;) LOL on of the big reson I like it, give you very ez access to the fuel rail and the Injectors with out moving any thing at all But it is your call And the Victor does look like it can be mabe to do the power ban you want.
