Kevin, you should perform a search of Jay Brown over at the FE Forum. He has done a couple (or more) intake comparisons with almost every conceivable intake known to mankind. I'll try to find a link for you, if I get the time.

Kev, with the cubic inches you want to run coupled with a solid roller you need to stay away from dual plane intakes, especially the sidewinder. The Victor that you were talking about earlier is your best bet for feeding that beast. You don't want to mis-match components.

Kevin,

I ran a Sidewinder for several years until an unnamed person talked me into trading my Sidewinder for a new Blue Thunder Medium Riser. Huge loss of power and performance. Go with the Sidewinder if you have the opportunity.

Dave- I only have one photo of the side winder and did not notice it's a dual plane.

Clois- what were the differences ?

There's a side winder on ebay right now. I do have a new Victor Jr. that is sponsored but, I have not done much reading about the side winder so I'm curious about it.

I ran a Shelby Sidewinder, I think it's a vintage intake, and a Da Vinci 950 cfm Holley on my car for about a year and half. It ran smoothly and had tons of power. Went to Webers for the throttle response and eye appeal, and don't regret it. Webers aren't for everyone and the Shelby Sidewinder set up is really good in my opinion for the big block FE's.

I have the whole assembly, including linkage and Kirkham turkey pan if anyone wants it. Shoot me a PM if interested.

Then again Jay wasn't testing these with a 527" monster with BT CNC'd heads and a stout mechanical roller. Basically, all this info is totally worthless for Kev's engine. It's apples 'n oranges...

My experience is that the Sidewinder out performs all other stock intakes at the low end and especially for top end. I have ran a 2 x 4 set up, Edelbrock MR, and Blue Thunder MR. With the Sidewinder my engine pulled all the way through the power band like a freight train. Massive torque and in your face performance. I sold my sidewinder for $600.

This looks exactly like my old one:

except I closed the oil fill extension.

That's correct Dave. Type & amount of porting and match up to the heads can be different from any builder.

FWB- I'll look over the link tonight. Thank you.

Clois- that's the one I mentioned for sale. There's 6 bidders and I'm sure it will go way past $600 What do they usually go for ?

Kevin, which carb are you planning to run and are you going to use this on the 428 in your signature?

Jim

the short answer is no....

why is it in spite of the testing done by jay which was very extensive on a dyno still believe the voodoo told by others sitting in their armchairs who have never used but two intakes in their lives with questionable carbs and builds?

i don't know the answer....but i do know jays results are correct and the numbers don't lie.
on the same note, lucas electrics........they sucked in the 60's they suck now, why would you incorporate them into a new build when there are far better choices?

same unknown answer.....

here's that monster motor the testing was done with...



- 428 + .030", stock rods, forged pistons at about 10:1 CR, CJ pan/windage tray
- C6AE heads, CJ valves and very minor port cleanup
- Crane dual pattern hydraulic cam, 272/284, 216/228 @ .050", .531"/.561"
- FPA headers, Holley 750 vacuum secondaries carb


was jay's brother's motor before it was put into the car.

gee it seems it is the same motor......wow imagine that......huh.....

Jim- nope, the sponsored carb is by Quickfuel. We still have to decide on the cfm but, it will be around 850. Most people use way to big of a carb thinking it will make more power, and that's not true. Talking with a few engine builders, for the motor I'm building, George Anderson's guy's use a 750 on their big Shelby engines and Dennis & Keith is apx. the same thought.

I need to update signature when the motor's done.

I'll be starting a thread about this all sponsored paid, Genesis 427 side oiler. Dennis of Pop's Engines, will punch it out to 527 cid, mechanical roller cam, aluminum heads ect..... The build will be in Car craft, Kit Car Builder and one other magazine. We will be displaying it and my Cobra at the "Run & Gun" in Sept. and George Anderson's (Gessford Machine) newer road race track.

I'll try and let you know when I post the build. For now, look at this website that most of the photo's and video's will be home at. Here on CC, I'll add the links and most information.

We will be taking photo's and video of the entire build. From the block, all parts used, machining, engine & chassis dyno runs.

This is very exciting for me and I hope all others here on club cobra. I just hope that everyone will be respectful of all the parts and engine builder that I've chosen. There are many top quality parts, machining techniques and engine builders out there to be used. Some people here and on FORD FE, are just plain jerks and all they do is complain !

Wish me luck !
