I suppose this is as good a place as any to waste space. I debated if this was shitalkers and shitheads material. Since i am both and have plenty to bash i figured we might give it normal consideration. Because im jealous gaymc can discuss this and i cant. Because someone is naive enough to ask gaymc and expect a resonable intelligent answer. Lets pretend i was considering making a logical decision and invest in fuel injection. Which is a reach but nonetheless worth consideration. What would YOU do given the choice? What would YOU do given the advantages of both? What would YOU do given the point and porpose of YOUR old car? Yes i am blatantly ripping a topic from gaymc. Just becuz.

LSx engines come with fuel injection. I think it would be incredibly cool to install a new Pro-Flo. I just don't know if I'd spring $3500 unless I intended to DD the car.

I hear tell the updated amc proflo will have a substantial price reduction. Thats a rumor. I dont get why you can get one for a sbc and its approx 1700 and one for amc is 3500 and the only differences is the distributer and manifold. I know everyone has their own ideas on whats good but i honestly think a crank trigger wheel and sensor would be better than a dual synch distributer. They could make a trigger wheel that would bolt between the damper and pulley simple and cheap and move forward.

Crank trigger would be sweet. You'd think the difference in price between all of the obsolete V-8s would only be a couple hundred bux.

We know how to design a bolt on crank trigger. The Jeep guys are all over fuel injection. I have a IH guy interested in a 401 but he want's fuel injection. My Daughter's Javelin runs like a top most of the time but it would be nice to have it run perfect all of the time. I am just too cheap to make the investment right now. www.ifsja.org/forums/vb/forumdisplay.php?f=94

I bought a eddy avs-2 carb. It was 320 bux . It gives f.i. a run for the money. Really one of the new “ carb replacement” type injection kits, for the money, well the kit and the price of comprehensive install, aint too bad. I can still buy three new eddys of 8 or 10 used holleys for the money. Good thing about the new wave of fuel injection is it is flooding the market with cheap used carbs... well they need the corn fuel sludge cleaned out but cheap is cheap. Corn fuel sludge is a whole additional modern problem that makes injection look good

When I can buy an EFI in great shape for $20 at the Swap Meet. I will go with it. till then, it's carbs for me. We've bought new carbs in boxes for $20. I do have enough skill to make them work properly to drive every day. I may not be able to make one work worth a crap on Stickshifter's car, but $20 guys like me will never be anywhere near his level, even in our dreams.

I know this is an old thread. A good friend of mine has done 2 Holley Sniper installs, with a third coming up after the new year. One is on his sons '70 Chevelle w/a 496....full interior pro-street car, driven a lot, has run a best of 11.60's n/a, 10.52 w/a 150 shot. We installed the Sniper earlier this year, hasn't been to the track yet, but drivability wise, he loves it. The more he drives it and it learns, the better it runs. Time will tell ET wise, but so far he's happy. The second install is a '55 Ford pick-up street rod with a 460. Basic rebuild on the engine with a real mild Melling cam, already had an Edelbrock Performer. Same deal, real simple install, and runs better the more he drives it. He wanted fuel injection because it ran shitty when cold, so his wife wouldn't drive it. A new carb tuned right would have most likely solved that problem, but he had the $$, so we got him a Sniper. The third install will be on a 454 Chevy going in a '66 GTO. The local Pontiac guys are gonna go ape shit when it comes out just in time for the Spring car show season.

Well the pro flo 4 has me thinking. My main problem is pump gas and carburetors is a pain in the ass. I have adapted to it, with electric pumps to fill perpetually dry bowls, tried to keep the carb cool to lessen the fuel boiling off, tried additives, keep a spare carb cleaned out and ready to swap out, have tried to love the 10 percent loss in power corn fuel gives, living with the smell of gas i get after running the engine. Yep it all sucks. The only time im ok is when i have a tank full of ethanol free gas. And i dont need hi octane. 87 octane is just fine. So the biggest advantage fuel injection can give me is i can run pump fuel and not die from the evaporated fuel fumes. The avs-2 is an awesome carb. It can be near freezing and the engine starts and idles smooth on a stone cold engine with no choke. The throttle response is fantastic. I dont think the pro flo injection can improve much of anything, other than stop the goddam gas fumes. Oh and i don’t know for sure, but suspect it would give more consistent bracket racing over a carb ( which is important to me). So i have laughed at fuel injection for years, but am really considering it now.

I've become convinced that EFI is the cat's pajamas.

Efi does a good job with gasoline that has been ruined with ethanol. If it werent for that i would prefer a carburetor. Efi has to have an oxygen sensor and a leak free exhaust, a high pressure fuel supply with return, various sensors, a boatload of wiring, and worst of all a delicate electronic control, all of which make it a failure prone overly sophisticated pain in the ass, to afix to a very hot vibrating engine, all of which are degrading every time it heat cycles. Because of plastic, which hates engine heat. So i still think engines and electronics will always be at war with each other.... A carburetor and ethanol free gasoline is a economical solution to the ills of electronic fuel injection. Efi is a expensive and generally unreliable fix for the ills of ethanol which will apparantly always be added to ruin perfectly good gasoline. Both systems would be better off with gasoline. We would get better power, milage and fue system life. Unfortunately the world is run by idiots.

The world is run by idiots at the behest of the greedy and power hungry. I'm really not convinced that EFI is less reliable than a carb. At least not when it comes to factory equipped Japanese EFI. Aftermarket? Who knows? All of the Japanese junk that I've had over the last 20 years has been incredibly trouble free, and all but two have been EFI. The carbed ones were way more tinkery than the EFI cars.

True both systems can fail. Electronics have come a long way. I had a lightning strike wipe out my vintage kenwood stereo . So even the best electronics can fail.

I can fix those old Kenwood stereos. Probably better than I can figger out what's forked in a distributor.

Never a lick of trouble with my GTP for 254,000 miles. Only a Temp sensor wire shorted out cause of Rodents. Hence why they quit making the 3.8. They improved it so much by the Series III, it was too damn good to keep. People wouldn't be buying new cars.
