The thread about "breaker-less ignition" is interesting but there is no general answer of which is better, points or electronic ignition, IMHO.
I think it is totally dependent on the application and use of the car. I have had a original Pertronix in my 62 for 20+ years with no problems.

I have used, played, screwed up both original Rochester fuel injection and EFI. Which is "better" is also without a answer IMHO.

I have had a first design 4360 unit on my 57 (sold) which performed flawlessly for many years under all conditions, hot, cold, etc. It was tuned by a professional and that was the key to good operation.
I now have a old Hilborn 8 stack mechanical injection which I converted to EFI using a FAST EZEFI 2.0 controller. It also runs very well and is actually pretty user friendly and even I can adjust and mess around with it.

So which technology is better? I like them both.
Any comments?

Technology is only good as the person who is using it. At the end of the day if it gets the job done how the user wants it done. Then that is all it matters. My one dumb Holley carb, points, and repro wires makes my car run great and can smoke the tires at will

I hate percolation; equally hate vapor lock. They are mysterious issues. My clone carbs on my 270hp '61 never once suffered from heat soak, percolation or vapor lock.... I personally rebuilt those, sold 'em after 20,000 trouble free miles and another forum member has run them, untouched, for another 30,000 miles.

My lil ole mouse motor 63 also with a WCFB suffered from heat soak, which I solved...now on the hottest days in Orlando it'll vapor lock while underway and cause an embarrassing excursion to the side of the road to cool down for 1/2 hour. Yes, I rebuilt that carb too.

I freakin' don't get it.....it has me considering an F/I conversion just to make the car driveable... So, in short, I'm on the fence about induction technologies..

I start to get vapor lock if I sit at traffic for longer periods of time start to back fore and run like crap and If I shut my car off and let it sit for a couple of minutes and turn it back on it will star to act up. I thought of putting a spiral fan inside the shroud and hide a remote switch underneath dash. Help cool everything down

One old timer told me to put tin foil around the fuel pump line to carburetor.....I'm not sure how that will help??

My car runs great as is, so I have nothing to contribute.

However, here is another tip from the "old timers"

Rich,
Some of the young guys might not know what they are, can you get them at AutoZone?

Rich Yanulis

Not AutoZone.......Your best bet is probably Kmart.

But you better hurry, because Sears/Kmart will cease to exist in the near future.

EFI is superior in every way except simplicity. Fuel economy, emission control, driveability, reliability, maintenance, and performance. Even engine longevity is improved (more complete combustion, less unburned fuel and byproducts sneaking past piston rings). No carburetor ever built can match a properly-functioning EFI system in any way.

I was very slow to come around to this opinion, thinking for years that the relative simplicity of carburetion won out over the advantages of EFI, but I can no longer accept that argument. It just can't match up.

Live well,

I think you answered your own question.

Read my reply and others in this thread regarding vapor lock.

I am a BIG fan of the Rochester, gas just doesn't like it tho.... so now it is converted to EFI and it runs flawlessly with the crappy gas...

I used to use a CD ignition with regular points and it worked flawlessly too, but that is gone with the EFI...

where one can get it trouble with new technology is when it is 'old' and no longer supported. I am now the possessor of 3 'orphans', an Accel EFI, a HotRodAir a/c, and a Keisler SS700...

Bill,
What ECU do you use?

you got it all on all points, but when something goes wrong it can be troublesome to diagnose and you need some expensive tools to do so. and that part scares most people and takes the "weekend" mechanic away. for most if a nail file, and a flat screwdriver can't fix it they have more even simple tools to diagnose

ganshert

lets see some pics of the Hilborn setup please! that sounds sexy as hell!

Hello

Ok that's a new why clothes pins ?? Keep the gas line away from the engine??

Yeah I am almost at the tender age of 49. I remember those used back in the good olds days lol Grandma and Mom used those ancient artifacts back in the day...

wmf62

surprisingly, the intent of the clothes pins was not to keep the gas line away from the engine; I think it was some 'voodoo' magic, or just an additional heat sink...

whatever the purpose or the results, there were 'true believers'...

The clothes pins do the same thing as the fins on a radiator which are part of the tubes that the coolant runs through and disapates the heat away from the tube or in this case the fuel line. It will work if you can get enough of then on the fuel line to make a difference.

ohiovet

My Hilborn converted to EFI.
Note there are no fuel rails.
Iwill post some better pics tomorrow.

Clothes pins are a total urban legend. Wood is an excellent non-conductor of heat. That's why its used for carb heat spacers. The pins are nothing like the metal fins of a radiator or the heat sink on a power transistor.

The clothes pins have about as much effect as slaughtering a goat and spreading the entrails across the motor.
