I am looking for better driveability, performance and gas mileage. Especially driveability. I drive about 3 to 4K a year.
I will be trading labor for labor so it should work out good. The more I think about it the more I think I am gonna go for it. I told him I would give him a call tomorrow.

IF, as Mike says, i didn't have gasoline problems (ethanol perc in the summer in traffic), i'd still be using the Rochester. as it is, i have no problems with the EFI.
i think the approach you are considering is a much better approach than the carb replacement type of EFI (Atomic & whatever).
go for it and let us know.

Do it. You will have it professionally installed, so I will not go thru my list of do's and dont's for EFI. I am no expert but know the pit-falls of EFI.
427 HotRod (Jim Moore) will chime in on this. He has a Holley system on his big block. I do not have EFI on my 61, still have my 2 x 4 WCFB's which after 46 years and 200,000 miles, I easily run them on my 400SBC.
But, I am tempted to go to EFI on my 61. However, I put EFI on my 400SBC Avanti. It operates great (i had no problems with a carb) and just makes a more drivable car.
Several of our Corvette group guys have installed EFI on their C-1, C-2, C-3s and like them.
Advice:
1.make sure the exhaust system has no air leaks, dependable O2 sensor A/F ratios avoid 99% of the problems.
2.make sure the guys installing it TEACH YOU about the software (they are all pretty simple), but once it is the way you want it LEAVE it alone. Professionals tend to milk guys with add on EFI's.
Jim and I know the Holley EFI guru Doug, if you get stuck with older software or components on a used system, he is great guy.

Too bad....
I'll have to say something for the defense of a good running 4 barrel, 400 small block.... an the feel.
When the back carb barrels kick wide open......No FI can sing that sweetly...and not many can keep up.
Some stuff is timeless.....and simple to fix.
I'm having to make that choice myself as we speak. For me it's all or none. If it's FI...then it's gona' be on top of a LS block. But wait..while I'm at it, maybe I should just get the LS in a new car with a warranty. Hmmm......nope, something gets lost in the translation there ...just not sure where it ends or begins.
I guess in the end ...it's just what makes "your" heart sing when you hammer down on it...nothing else matters if you don't have that.
Best of luck, and happy trails...Stan

If you have an LS-? then you are already in the game and they run phenomenally. If you have an old "dog house" Rochester then lube your hood hinges when you install it - you will be under there a lot. UNLESS you run a hybrid like WMF62 with his ingenuous setup.
A carb-to-wet flow throttle body swap is problematic. If you have ideal, pristine conditions and operating environment then there is a 50% chance you won't be throwing $3,000 down the toilet.

except when i caught the car on fire
(and that was totally my fault), i have NEVER had a problem in 45 years with the old Rochester FI and would still be using it if the gas we have wasn't so crappy....still have the original unit in a box; but, unfortunately, it will probably stay there...

Hello, I am looking to use the same Edelbrock fuel injection set up in my 56 but was wondering if hood clearance would be a problem as I thought the newer systems were a little taller then the original style from back then. Looking at your picture is seems that the unit isn't any higher then your distributor, so I guess it fit pretty goodY Did you have any other fitment problems?
Thanks,
Kevin
