427 FE Tri-Power

like in my other thread. Y’all used to know me as Ghost Torino GT. I was originally building a 460. I made a thread about the tunnel ram. Luckily for me I found my true dream engine. A 427 FE. I managed to get my hands on a tri-power intake and I built some carburetors for it. I also got some factory 427 low riser heads, a ton of FE parts I gutted off a 390, including a high flow oil pump. I haven’t got the camshaft and lifters yet. My 427 was cast after 1968. It should accept hydraulic lifters. I have rocker arms for that.
I plan to order a custom camshaft. And running a factory ford rated stall converter with a C6 transmission.

I’m looking for extra tips before I go any further. Factory ford HP rating was 425 HP. The same or more power will make me happy. I want my car to be a real performer. But not to unrealistic extremes.
 

fords older fe series

back when I was in college , several of the guys I knew owned a 1967 ford two door fairlane with a 4 speed trans and a 390 or 427 ford engine, and when properly set up the cars were competitively fast on the street...

where are you physically located (city)
your ip address appears to be close to mine (farmersville texas)
 
Yeah, the guy I bought the 427 from lived pretty close to you. I was building a falcon and sold me the engine for extra money. I met him in Corsicana and him and a friend slid it to the bed of my S10. Considering the traffic. I should had just drove all the way to his place.

Edit: I’m reading the links. I read several books on FE engines. I just doing last minute homework before I go any further.
 
Okay, my heads have a 73-76 cc chamber. I’m going to lower my CR just a bit lower than factory. I’m going to order a custom made camshaft. I was going to go with rollers but I decided for a custom flat tappet.
Now who here has experience with ford 3x2 set ups?
 
Ive certainly set up several tri power big block corvette intakes, but not ford three deuces
basically you set up the engine to idle on the center carb. and then jet and set up the two outer carbs to kick in at identical rates after the center carb gets to about 1/4-1/3rd open, and set the accelerator pumps on the outer carbs to start kicking in at the same rate
yea a manometer helps

1984 crossfire vette won,t run right?

I have a 84 crossfire injection corvette I set the timing and it misses horribly if I advance the timing it idles high but takes gas better but still misses and stalls the computer throws code 51 I have two ECMs I've tried and two different chips still same problem and same code BUY A SHOP...

thank you. I bought brand new carburetors for my intake. I found a site called HP trends. I bought new carburetor based off the cfm ratings.
Now I’m willing to buy a new edelbrock 2x4 set up. But my heart is set on my 3x2 setup. Not for power but for historical purposes.
 
there are a dozen ways to install three two barrel carbs, or even 4 two barrel carbs
keep in mind the old inline three deuce config can be either based on 1950-60s tech, or upgraded considerably, you could even modify a tunnel
ram intake generally used with dual 4 barrel carbs to run a modified three deuce carb config, and there are several larger high flow 2 barrel carbs available that flow far better than the original three deuce carbs ever did.
Id also point out that if you have or know someone who has a milling machine and a TIG welder your imagination is almost the only limitation

certainly the original ford three deuce config leave a great deal of area for improvements, especially if your not concerned with hood clearance.

and there are adapters for fe engine to other intakes, it is not cheap but it is easy to do if you have deep pockets

why not post several clear pictures of the intake and carbs taken from several angle's
have you port matched the intake?

porting can help

I had to buy new carburetors new off summit and turn them into ford style carburetors. Holley doesn’t make carburetors for ford tri-power. Not even close.
The center carburetor is 325 cfm and the outer carbs are 350 cfm. What I found on the internet that most people agree on is ford originally had 320 cfm on the center and 350 on the outers.
On Facebook a lot of people gutted a lot of generic two barrel carburetors and force them to work as a tri-power setup with mixed success.
And some got Chevy tri-power carburetors meant for corvette applications and complain they didn’t work. Or used factory carburetors on stroked engines. I decided to replicate what ford did from the beginning the best I could. That’s why I chose low riser heads. For what I read they are similar to the 406 heads. And I’m keeping my engine as close to the original displacement as possible.
I’m not trying to shoot to the moon with horse power. The factory rating for the 427 was 425 or more. I will be happy with that. If I get more that would be great. I plan to buy a custom camshaft made for my engine combo. I plan to improve my car around the engine. Like upgrades to my transmission, electric fan, improvements to engine cooling and so on.

My intake has been modified and everyone that looked at it agrees that that the previous owner probably tried to rig up a vacuum linkage on it because a very good tap job was done to it. And spacers were used. I already had some of it fixed. But I plan to have a machine shop plug the holes. The mechanics said there isn’t anything wrong with it as the can tell. I can’t tell if a port job has been done to it. I can’t get to the intake right now.
The guy I bought it from didn’t use it. He collects parts and sells them.
