Hopefully I can rework my tone a little. Its not based on what I do, but what you can see yourself doing.
Based on the expert work I've experienced first hand with the Corvette multiple point Crossram and Crossfire, there is no way I'd "personally" use FiTech stuff in a 2-bbl situation due to the shot gun splatted of trying to level one caterage of lead into six holes.
I'd spent 50 bucks on two HSC 2.3 carbs before spending a cent on the FiTech...see below
GM went through this through the Maliase 1978-1981 and Alphabet Soup Era (1982 to 1992, the death of English letters, start of Greek).
The issue has never been that TBi doesn't work, its that TBi doesn't work well on in line sixes.
Ford used Nissans Pathfinder VQ30E Throttle Body Injection on its 1987-1991 EA 26 3.2 and 3.9 engines....it was two K car Chrysler carbs in one 32/36 style package.
To get that 2-bbl TBi to work, the intake had to be like this.....
to make it work, it needed major 1968-1996 Argentine ME 188/SP 221 like 2v manifold surgery details
I would find a 165 hp CrossFire Z28 5 LITER 305
205 hp L48 Crossfire 1982, 1984-1986 Corvette system, which is just two 4 cylinder throttle bodies.
Them before I'd spent any money on an 2-bbl EFI.
Even if its a company as well respected as FiTech is.
Factory 5 and 6 liter twin point TBi EFi uses the most delightfully simple to balance systems ever made.
I'm swearing, and using the Chevy word, but....MOATB! (Mother Of All Throttle Bodies) .....

The idle tracking the TBi 1 to TBi 2 balance, its all been done.
Every early Chevy Cavalier or Iron Duke TBi car is your friend.
And if you've ever seen a Rambler 196 engine, the arrangement of the two carb set up that
OpelGT+3point3 is doing is perfect for twin 1-bbls.

I took a few pics showing the size of the intake ports and the angle I cut the tops off; toward the valve cover. Plus with some studded head bolts inserted to provide an anchor for eyebolts to attach the new intake. I cut the angle because I want the intake lower; coming out level instead of upwards. The upper section I angled off was the inner radius of the curved port; it will be a smooth transition without any severe angles. My head is cast steel as denoted by the grinding sparks; light yellow and very long, instead of short orange like cast iron. I'll try again later to upload pics. I just want one small four barrel, like a 390 Holley or an old WCFB Carter or Four Jet Rochester. Something about 400 cfm with vacuum operated secondaries.
I've worked with the Wrought Cast Carters before, both Double (WCD) and Four Barrel (WCFB)
Mainly GM crap like Buick 8's and 62 Vettes. Before those in 2011, I was probably influenced by the GM in line Pommy sixes, and the whole thing was the simplicty for setting up multiple carbs from the indermediate shaft on the firewall. Falcons have that same key idea...simplicty!
The WCD I like more because the parts situation is easier, and again, I like the easy GM linkages, and the single Twin H Hudson Hornet air cleaners that come with them.
If you use the Rat Roster Cross Ram Smoky Yunick style plate on a 6 cylinder,
I started in 2011, but got busy earning a living
My background was twin carb CrossRam and Twin throttle body Crossfire Chevy intake manifolds, so when I found the old AMC/ Nash six cylinder stuff, it was a slam dunk to do it on a Ford log head six.
