The GM 2.5L TB flows more than a YF though. At least the butterfly is a lot bigger. Just based on the butterfly size the GM 2.5L TB flows more than a Carter WCD 2V carb. The GM TB is something like 2.25" in diameter IIRC. It's been a long time since I toyed with the idea of using one on an AMC engine. It would work well on a bored out 1V intake and give a little more power than a BBD 2V -- but the main gain would be driveability. A long six really needs injectors at each port. Someone (Jim?) mentioned figuring out how to inject a 196. The 1V TBI would work great, but the side of the intake "trough" could be directly drilled and tapped for injectors. If the computer wouldn't object only four would be needed since cylinders 2-3 and 4-5 have siamesed intake ports. I wonder if one could just connect two sets of wires to one injector (with diodes to prevent feedback)? Those two injectors would get a lot more use than the other pair, but shouldn't be a problem. With a batch fire system it should work, sequential would depend on how close the siamesed injector cylinders are in the firing order. Of course two injectors could be installed side by side. This would work for the L-head too. Now that would be something -- a port injected flat-head six!! There are Stromberg carb body based TBs out there now. One of the hot rod supply companies made them for two and three deuce setups on flat-head Ford V-8s. ---------------------- Tom wrote: I did calcs and drawings for a "FI Carter YF" (up to 250HP). Can do it with a single injector, in a modified YF. I think I know how to measure air flow and engine demand w/two pressure sensors (need to proof that) in a hacked up YF. No need for recirculating fuel or even tightly regulated fuel pressure -- simply adjust pulse width with instantaneous pressure ("area under the curve"). Idle air is in a YF already... simple thermistor for carb temp (good enough for the carburetor, close enough to coolant :-) Everything but the fuel boost pump could fit inside the carburetor body -- electronics too! With feedback (wide-band O2) I could make it primitively learn. To proof it I'd need a "flow bench" air pump and flow meter to characterize my flow/demand measurement with two pressure sensors. If that works I know I could make it go. Closed-loop software servo systems I can do. Too many possible projects in the world though. ------------------------------ Message: 2 Date: Fri, 8 Dec 2006 08:10:19 -0600 From: "Swygert, Francis G MSgt 436 CES/CECM" <Francis.Swygert3@xxxxxxxxxxxx> Subject: Re: [AMC-List] Fuel Injecting the big Dogs To: <aje1@xxxxxxxxxxxxxxx>, <mail@xxxxxxxxxxxx> Message-ID: <4CC05BF0CC3F114281434B00B733E2A313C749@xxxxxxxxxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset="us-ascii" Armand, everyone I've ever talked to about the Holley EFI system has said "spend the money for the closed loop option!" (back when it was an add-on, which was after the first kit came out). The first Holley system was really made for the drag strip, not street use. You had a control box and had to set everything! The only racer I ever talked to that used it successfully and really liked it kept a chart with key measurements (temp, humidity, altitude, 60' time, 1/4 mile time) for each track, and what settings were used. He would then take those readings before a run and make the proper settings. Car was pretty consistent after a couple years running. Every time he made a change (cam, jets, whatever) he had to make an estimate of the settings then start over keeping records. He got good with it -- after a half dozen runs it would be pretty much dialed in. To get the best results on a street vehicle you had to make minor adjustments all day. A carb was better! He never tried it on the street, realizing the amount of adjusting that would be needed to make it superior to a good carb. The closed loop kit made it streetable, but it was still hard to adjust until a computerized tuning system was introduced. The old ones had four or five dials that were adjusted manually, no computer interface that I recall. The Edelbrock system is great, but there's something they don't tell you in most of the literature -- you need a PROM programmed for the base-line. The Edel EFI is made by an OEM supplier for Edelbrock. When you buy it you get a card to fill out with your engine parameters. The company then burns a PROM and sends it to you. THEN you can program the computer -- or rather fine tune your engine. The computer still only has so much +/- adjustment from the base-line parameters. To me this isn't a truly programmable system. If you swap cams you will most likely have to have another PROM burned, unless the difference in the previous cam is relatively minor. If you like to tinker with the engine and try different things you'll quickly run out of adjustment range. If you have your engine about where you want it and don't plan on making a lot of changes, this is great! Otherwise you need a truly user programmable system. As far as user programmable and affordable systems go, there are two that I know of. Both require a little work on the user's part. They are just computer and wiring systems, you have to adapt/furnish intake, wiring connectors, and sensors. The first is the MegaSquirt (http://www.bgsoflex.com/megasquirt.html). Depending on your level of electronics skill, you can build the thing from scratch, a bare circuit board and parts kit, or buy complete from several different vendors who will guarantee them. Glen Hoag is a dealer for ready to go controllers (a list member -- www.glensgarage.com -- for an article on one of his units see http://www.olenik.com/tvr/tvr.pl?page=fuelsystem). These have been used on everything from lawn mower engines to turbo V-8s, and I think on a couple Jag V-12s. The most complete unit that has been around longer is from Simple Digital Systems (www.sdsefi.com). This comes with a hand held programmer. It's made in Canada and has been around since 1993. Costs more than the MegaSquirt, but it's more sophisticated too. It's even been used on aircraft (but isn't certified -- home builts and owner conversions)! I've watched this one develop for a while now, and if I were going to use a ready made aftermarket system this would be it. I don't think anything else is as flexible at the price. There are similar systems out there, but all are more expensive and/or limited. The new Racetek system has the advantage of being all but bolt-on and drive. You still have to connect a computer to put in the base-line info. But this is about as easy as it gets -- bolt-on, plug into your desk-top computer, answer a questionnaire type program, install ECU, then drive!! Not a lot of tinkering -- the system adjusts itself as you drive. ------------------------------ Message: 3 Date: Fri, 8 Dec 2006 09:21:46 -0500 (EST) From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) Subject: Re: [AMC-List] 232 Trans into a '64 American..

Switch to an electronic system and most of it will go away! While rebuild quality has slipped, I don't think that's the problem here. Even a new distributor built to OEM specs (or even a little tighter) will give similar results. Might be a little less "jitter", but still +/- a degree or two. Pertronix is the easy way to go! ------------------------------ Message: 5 Date: Fri, 8 Dec 2006 7:18:01 -0800 From: Mark Price <markprice242@xxxxxxxxxxxx> Subject: Re: [AMC-List] 232 Trans into a '64 American..

When I swap to an actual Ford World class trans I will be changing it over to the AMC15 tailhousing! AMC did not use anything on that tailhousing that matches any other T-5 except length. Shifter placement, Speedo setup, mount are all different. I wish I could find a "core" AMC T5 to pull a tailhousing from. I realy hate to tear mine apart. Near as I can tell it has never been touched and even being 24+- years old it works flawlessly! I can't seem to locate an AMC T5 tailhousing. I may post it over on the forum again, one last time.

Points?! Me, points!? Not on your life in this car! Duraspark II, big Ford coil, 8mm wires, big cap, ...! It's either the Duraspark distributor, or the timing light, that's got the jitter. I may repeat the test and fiddle with the placement of the clamp-on pickup to see if it's that. Otherwise, it's a bum distributor. I've not found a good-as-new used or rebuild distributor (or carb, or starter, for that matter) in years. Cardone is fair, and Tomco is crap. Part of the problem is simply cores are all worn out I guess. ------------------------------ Message: 7 Date: Fri, 8 Dec 2006 12:28:51 -0500 From: "Widiker, John D" <john.widiker@xxxxxxx> Subject: Re: [AMC-List] Fuel Injecting the big Dogs To: <mail@xxxxxxxxxxxx> Message-ID: <053E34168692C4438533FE33E79C1A181233F7@xxxxxxxxxxxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset="US-ASCII" Now that MegaSquirt has been brought up I've gotta chime in. The controllers we use at our shop are all MegaSquirt. My AMX is getting one with a custom manifold, my 64 Tempest uses 2 of them, one to run the vortec 4.3 and the other to run the 4L60E. We offer stand alone setups installed and tuned and when we are doing something really odd we call the guy who wrote the coil pack code, he is one of our good friends. He splits his time between Michigan and Florida so we line the really off the wall stuff up with times he's here. Our turbo probe runs no stock computer or wiring and has been putting 350 horsepower to the ground with a MegaSquirt for a few years (previously we used an FMU and the M/S is making much more power and runs better). MegaSquirt can now use wide bands for those who want them, has an autotune feature, can run coil packs (I'm cutting my old amc disty in half to only run the oil pump), can control water injection or any 12 volt system in a variety of trigger schemes. EI: at 5 pounds boost start water injection, at this percentage of throttle position do this or that, etc. They are batch fire which some people don't prefer but we've had zero problems with them once they are set up properly. We do sell completed units (through PRD) and have bought stuff from Glensgarage previously and have never been disappointed with his stuff either. ~John -----Original Message----- From: amc-list-bounces@xxxxxxx [mailto:amc-list-bounces@xxxxxxx] On Behalf Of Swygert, Francis G MSgt 436 CES/CECM Sent: Friday, December 08, 2006 9:10 AM To: aje1@xxxxxxxxxxxxxxx; mail@xxxxxxxxxxxx Subject: Re: [AMC-List] Fuel Injecting the big Dogs Armand, everyone I've ever talked to about the Holley EFI system has said "spend the money for the closed loop option!"
