Really? If anyone has that article I'd like to see it.

The manifold in the article may very well also be a ramport or something like on the callaway Twin Turbo 100+ setup.

I found that article,but it isn't same manifold.The manifold at article was modified Edelbrock TR1Y tunnelram with tpi top and throttlebody.It was designed by Chevrolet engineers to 5 liter Camaro~275hp.It was -89 HRM january page 22.

Can you scan and post it??

On the subject of prototype manifolds, I thought I'd post a few pictures of a Trans-Am prototype that Falconer developed for Pontiac. I bought this one from Erik Falconer a couple of years ago.

nice!! in a selling mood? sort of looks like the big block kinsler crossram originally designed for GT1/IMSA C3 Corvettes. It's not for a pontiac, it's for SBC pontiac motorsport heads from the looks of it. Sadly a lot of those heads are now hacked up beyond repair.

ericjon262

Cool manifold, I was wondering what heads it used after looking at the bolt pattern. my quess is that it would perform similar to a TPI manifold with high flow runners.

Looks like it's for an 18 degree head setup. It looks like they used a normal spider type 18deg manifold (carbed), machined the whole spider off and attached the 4 elbows with small countersunk allen heads.

Neil Albaugh

Yes, it is for Pontiac heads on a SBC-- I should have been clearer on that. I haven't bolted it onto anything yet but I do have a set of 18 degree heads so I might try it when I have time. Here are a few more pictures, including one with the port size marked on it.

Hey Twin Turbo, you have some really cool stuff there. Thanks for the pics.

micktroup2

That crossflow manifold looks like it was made for weber carbs, not EFI...

Maybe, put it appears to have injector bungs on the top.

Twin_Turbo

iTrader: (25)

Yes, it was originally for webers, it's modified. There are versions without the throttle blades and no injectors.

Manovox

what brand are those fabricated valve covers?

Twin_Turbo

iTrader: (25)

No brand, they were listed on ebay. don't think they are anymore.

Neil Albaugh

Twin Turbo, you are right-- I checked the casting number of an 18 degree intake manifold and it is the same as the one on the Falconer manifold.

LGAFF

any more info on this intake or feeback on performance? I just bought one of these for my 87 Callaway TT.

It also is the same kind of basic shape as the inside of the Firehawk T-ram

LGAFF

Probably should clarify.....this is the one I bought

TTOP350

iTrader: (8)

That is cool! it looks like it has been sandblasted?? whats it look like with the top off??

Twin_Turbo

iTrader: (25)

That's it, a mcfarland short ram.

Want to sell it?

TTOP350

iTrader: (8)

Hey, you prototype intake hog!!

LGAFF

So is this a prototype? Was it for GM or Edelbrock? Does it flow well with TPI heads, getting it PC'd wrinkle black and then putting it on my 87 Callaway TT

thanks

I'm not sure who it was for but supposedly there is only 3 of them.. It would be nice to have it copied so it can be sold !!

Twin_Turbo

It's aMcFarland short ram, McFaland had his own line of manifolds, like the torque link and some others. It's not a prototype but it's a very rare intake. Yours is not 1 of the 2 new ones off ebay so that makes it 4 confirmed in total. Mine has been modified but has the correct fuel rails, bolts and what not. The 2 new ones were bare, 1 came with an EGR setup (JerryWho's) the other was just a bare base & top. Looks like yours was actually used and cleaned up. Can you tell where you got it?

PCed black it would look like a Callaway 100+ intake,...nice!

TTOP350

iTrader: (8)

Did McFarland have a shop? catalog? or ??? Anyother info as far as its intended use? Boats? Drag strip/road course??

LGAFF

Guy I bought this from said in testing this intake was making more power all the way to 7K and it outflowed a custom Tunnel Ram and the SLP T-Ram

TTOP350

iTrader: (8)

I believe that, just by looking at it. Its what GM should have built instead of the TPI

LGAFF

Checked in with John Heinricy and he said that the intake looked like a prototype for the 1LE Camaro...got scratched for the LT-1 motor

Lee,
Better sell it to me. Heinrocket says it's junk.

Getting close to finishing my 87 Callaway TT:
Stock IHI RHB52W Turbos
Ported Stock Heads
2.00/1.55 Valves
Ported Exhaust Manifolds
3" Exhaust
GM prototype 1LE Intake(Mcfarland Short Ram)
Small Cap Dist
Mocked up the Intercoolers to check fuel line clearances:

Will keep you posted on the progress...appreciate all the help from 3rd Gen, you are a great group.

Twin_Turbo

iTrader: (25)

Awesome, to a novice that would pass off as a 100+ for sure. I assume that's why you wrinkled it black??

LGAFF

Found out one of the ZR-1 guys knows Jim McFarland......going to get the entire story on the intake

Twin_Turbo

iTrader: (25)

Please post it here I'd like to know exactly what I have also.

thanks!

Great collection!

LGAFF

Waiting to get moredetail, but Mr. McFarland confirmed this was a GM contract piece, there were 6 made...all I have so far will see if I can get more details.....

I am trying to get info on the perf objective and what dyno results they got as well as confirm the 1LE

TTOP350

iTrader: (8)

See if he can have more made!!

VincentZ28

iTrader: (2)

That would have been the best intake ever made for TPI. Wouldn't even need an after market company to make it.

It would be cool if one of these guys with that intake show to Edelbrock, BBK, Holley and see if they can copy it and put it into production. They will sell like ***** cats. A cool direct replacement.

Thirdgen89GTA

iTrader: (5)

They do sell something like it though. This is very close in performance to a HSR I'll bet. Look at how tall it is, the runner length has to to be pretty close.

VincentZ28

iTrader: (2)

Yea I know. I've seen Jerrywho's intake up close in person.

Twin_Turbo

iTrader: (25)

No copies!! no copies!! Cant have true art copied LOL

HSR comparison pics

VincentZ28

iTrader: (2)

It will work just as good as the Miniram and HSR. Just lose a little bit of torque on the bottom but make it up in the mid range and top.

Twin_Turbo

iTrader: (25)

This manifold is a lot more lively dow low than a miniram, I like it a whole lot better. Iy easily revs my 355 to 6K rpm, haven't done a dyno pull but it feels much happer up high. If you want to loose TQ get a miniram... it loses a LOT!

Is JerryWho still working on his? If he wants to sell..have him contact me LOL I could use a 2nd one.

TTOP350

iTrader: (8)

If your wanting to build a torquey motor, you shouldnt even be looking at a short runner intake!!
Short runner intakes are for large CI motors with big stroke cranks.. The extra stroke helps pickup that "lost tq".

Quite honestly, my motor only spends time at 2500k rpm going down the road, but when I hit the throttle, it spins to 3500-4k rpm and just pulls like a freight train to 8k rpm.
The joys of a stroked and poked n/a 400ci motor.

I do think I would like to have one of those Mcfarland intakes, def over the ugly, to tall for the stock firebird hood, HSR and maybe even over the mini-ram.
I like the fact that it has a VERY production like look, runners could be tweaked and the plenum is way bigger than the mini-ram.

Bottom line is, there isn't a all purpose intake out there. Every motor or project has limits, be it money or power goals. Pick the intake to suite what goals YOU have. High rpm tq and HP isnt for everyone, its dang pricey!

Savage388

Man if I had one of those short rams I wouldn't have a problem ripping my carb right off! It just looks so perfect for our thirdgens.

Twin_Turbo

iTrader: (25)

There's a difference between a short runner intake losing tq and a miniram, a no runner intake that is dead in the water below 3K rpm on a 350.

LGAFF

Got access Jim McFarlands personal e-mail......any specific questions anyone has?

I am going to cover

1)What project was the intake set for
2)What were HP/TRQ goals and were they achieved
3)Why was is scrapped?
4)RPM range?
5)CFMs....what was his impression of the end result?
6)Ask about the epoxy intake..
7)What is the purpose of the holes drilled in the valley connected to the intake port
