Where the heck did you find an old school mechanical fi setup? Those were all the rage in the glory days. It wasn't the best street setup but ruled at the track. I just Googled and couldn't believe that those systems are still manufactured. Hillborn to boot! You run this setup on your 2.3?
The pic below is from my buddy's hot rod shop. That's a real Ford Phaeton with a 289. A local guy manufactures and sells that stack injection setup. It's run by a Fast EFI computer. This car was featured in a Hot Rod magazine photo shoot in the 60's. It was yellow back then.
No no....I run a "bolt-on" setup from Ron's (flying toilet). Same principle as a stack-style but only one throttle body which bolts on to a standard spider-style 4150 or 4500 intake, and uses the 8 nozzles in the manifold runners. Real simple and real effective.
Ran stacks on a stroker 3.7 (Mercruiser block on a dragster, NA) before the owner of the car passed away. Custom setup. Sorta like that NHRA class where they run altereds with 4 and inline 6 cyl engines. I forget what they call it but same type deal but this one was a dragster and not an altered. 200" wheelbase Neil and Parks. Ran some high 9's with it. The plan was to get it lined out before hitting it with the nitromethane, which never happened because owner died and the car was part of his estate which was sold off by a worthless family member. Those old mercruisers were basically half of a 460 BBF--in it's original configuration it used an iron 460 head on top of the Mercruiser aluminum block. We had a modded A460 head on it. There was another fellow who had the same engine but with a turbo and it went into the mid 7 second 1/4mi ET's regularly-if it stayed together. That's what we were shooting for but NA on no more than 50%.
Mechanical FI can be used in about any kind of throttle setup as long as the rules will allow. 8 throttle bodies, 2, 4, 24 however many you want/need. We fabbed a sheet metal intake w/ twin blade throttle body and 10 nozzles up for a 6.8L Triton V10 that was going into a dragster but the guy I was working with married off and moved; and that entire deal got abandoned, unfortunately. I'd love to have finished it-or at least put it on a dyno. They sound a little different those V10's....NOTHING like a Mopar version (thank goodness). I just wish there were a set of 40V heads available for 'em. We were using 30V heads from a 2006.
And yes it's "streetable" (the race car)....have done it a time or two and it's not all that bad. Worst part is the fumes from the alcohol but when people get a whiff of it they either turn up their nose or they run away with burning eyes/nose/throat. I usually run some sort of fragrance in it to help take some of the "bite" away, strawberry seems to be better for that but they have it in chocolate, cherry, grape, vanilla, and a whole bunch of other fragrances.
Kinsler makes a trick EFI stack setup that I'd love to try but on my current project, 92 Mustang GT, it doesn't really fit that sort of car. Ideally I'd like to find a '56 Ford and do something like the EFI stacks on it, would look period correct. The problem with stacks is the responsiveness. They are extremely responsive; and in fact the few that I've messed with were a little harder to drive because of it, especially if they were a manual trans. Stack EFI on a 5.4L 32v would sorta remind me of a period-correct setup on a 427 SOHC if done correctly. Not many people use modulars, though. Seems like the newest fad is LS swap everything which I'm not a fan of. It doesn't look like anything period correct, not even close. GUy up the road's got a '51 Ford pickup and his neighbor has a '53 Chevy (car) and both are LS swapped. The '53 when the hood's up, doesn't even come close to what they looked like...not even a resemblance. Same for the '51 pickup obviously. My dad's got a '51 Ford pickup with the original 8BA flathead and it's got nowhere near the power of a stock LS 5.3, but it's smoother, quieter, and it's cooler. At idle, the flathead is absolutely silent. You can hear the brushes in the generator passing over the commutator as the comm spins--it's that quiet.
