This is a continuation of part 2. Please post new info here.

What's the CFM on the Holley Economaster carb?

> Also, here is an off the shelf Crane hydro-roller cam
> is this close to what I need?

Cam specs for that are:

216/224 (278/286 @ 0.050"), 0.562"/0.586", 112 LSA

The Lunati HR that George spied is:

211/219 (262/270 @ 0.050"), 0.559"/0.559", 112 LSA

Dan,
I'll find out what I can about the Economaster carb.

@ whatever depession they're using, they flow what you test them at. maybe you've seen this thread?
http://forums.vintage-mustang.com/vinta ... 302-a.html

but are we on the same page as to what an Economaster carb is? some ebay sellers call several Holley types 'Economasters'

http://tinyurl.com/Holley-Economaster


being a Q-jet replacement even with the small bores you still ~might~ need to use the adapter plate but i wouldn't be surprised if the bores did fit within the perimiter of the square plenum

in the first thread i posted the number of an Economaster, probably the best fit for you, there were well over 100 different OEM specific calibrations that Holley came out with
"Holley 4360 #7956 Economaster "for 351 C.I.D. eng, Mechanical secondaries, spread bore, integral choke w/elec. assist, Ford kickdown lever"
as most were set for GM's and will not have the linkage, did i mention 'good luck finding one' but you never know

all that said, for your project i still think you'd be happier with a conventional Holley like your 1850. i just remembered an old bud had a Fireball 266 & 1850 on what coulda been a 305 or 350, once he said he left for the city on E and made it back, darn thing was pretty uppity too, very responsive



there'll be phantoms, there'll be fires on the road... and the white man dancing

I also saw them referred to as an Economiser ...
Yeah, from what I saw they are 450 cfm, probably way to small for my liking.
The number on the carb are 9112 and 6R-5643B.

I also think I would be better off using a carb I have. Getting parts for this while broke down in BFE would be a problem...

Dan-
I rarely ever post here as I simply like to see all the other builds and vast amount of information here.

I was worried when we did the 2010 Powertour, I was worried about milage, I was worried about spinning my 1972 GTS too hard on the highway.
I'm running some sort of mild mystery build I got 15 years ago from a kid I worked with at a Buick dealer many moons ago, and the setup came from the Torino his mom bought new.

I had the heads redone 13? years back for unleaded gas, and replaced the seats, valves, and stuck in new rockers. By no means a hot engine, nor am I more than an average caveman knuckle dragging mechanic.
I run a 351 edelbrock performer intake, a 1406 600 cfm performer carb {I feel this is undersized, but I don't race my car...street driven 99% of the time.}
I do however have the joy of having my heavy Torino backed with a toploader and the close ratio gear set.


I am also running a set of old Dynomax blackjack headers, primaries are around 1-7/8" OD if I recall correctly...nothing special for $99 elcheapo headers.
I run a full 2.5 flowmaster kit with 70 series mufflers

When I was rolling around 55-60MPH on 2 lane roads which was a wonderful time...we managed 15MPG w/o issue.

Prior I had 3.50 gears...and I spent PT2010 running down the road around 3800 rpm in 4th. There were stretches I can honestly say I was getting gas every 140 miles @ 16 gallon fill ups.

I was worried about MPG, but calculated if we took our Ford Contour SE V6...we would have saved a whole $150-$200 ON FUEL.
Not even worth it.

This year, I tossed in 2.75 gears for my 2011 PT run, Omaha to Indy to Muskegon and back to Omaha. I burned up my speedo and drove by tach, and running 80 I was spinning 2700 rpm and I only used $430 for gas for the section I did this year.

Run the killer engine, swap in the trans, and don't seat spending an extra $200 on gas.

Trust me, life is too short to worry about it.

See you {hopefully} in 2012! Look for a big yellow and Grey 1972 GTS.

Andrew, Thanks for posting.
I'm afraid it is much more than just $200 difference for gas. I figure more like $1000 difference for gas. If it were only $200 I wouldn't have wasted anyone's time here in this great forum.
My guestimate is I'll put on 5000 miles next summer. Not just on the Power Tour, but around town and going to cruises, shows, events and just plain ass driving my car. 5000 may even be on the low side. It could be much more.
As stated my engine comes out and apart every winter lately so why not play with it a bit and see what I can come up with. This is a "Go" project. I started gathering parts and this Will happen. Whatever results I get I will live with.
Thanks again for your input.
please don't shy away from this forum. Post more often and enjoy
Cheerz.

Hi guys-
Dan, that makes sense. Myself, I want to change things up a bit on my GTS, but don't want to thread jack.
I may or may not make powertour for 2012...but if you happen to see my 1972 Gran Torino Sport, don't be afraid to say howdy.
...or give me three horn blows on a long stretch of highway to see what 2.75 gears and a top loader can do...with a mild 2v build...

Bill-
Yes, I had picked up a '74 Q code ranchero. She was pretty much chewed up and long gone by the time I got it.
Only thing I have left is the Q code specific power steering pump/pulley for my GTS, and the 3.25 center section from the 9".

If you need any parts or such, there is a guy out in the panhandle of Nebraska with a bunch of Ford stuff, super nice guy that runs a tow company.

Yeah, I'd like to know about that towing company as I have a 73 Q code Ranchero in need of restoring as well.
