carb vs efi
so i know i have been asking alot of questions on here and i thank everyone for there help and input. last question now for awhile i promise. i have been doing some thinking if you guys where to do an engine swap what would you do. efi or carb? now the efi would have to get a new custom made harnesses made. 4 cyl to 8 cyl swap. i plan on driving it a good bit at first and then if i have the money maybe do a little racing on the weekends

RE: carb vs efi
For performance, fuel econemy, driveability, probably EFI. The Carb if done right and tuned can probably match the EFI, but gives you that 'boost' feeling when the secondarys open up (mechanical - ie Double Pumper or Vaccum). I've said it before (HACK will agree), nothing like feeling the secondaries open up when your on it! ;-)

RE: carb vs efi
i have a carb on my 351, and i'm about this close to converting to efi...any questions?
seriously...i get about 7mpg city. highway is at least 15mpg. go with the efi. if you don't do it right off, you'll be converting later.

RE: carb vs efi
EFI is my vote.
why custom wiring harness?
junkyard or ebay or
http://www.latemodelrestoration.com/...0%201&comp=LRS
computer (5speed/ automatic available too)

EFI will help with emissions if that is a factor
Performance will about the same
EFI will allow for s/c or turbo to be added easier, though they do make carb'd s/c's too.

RE: carb vs efi
if your doing a swap from 4 cyl to 8, carb will be alot easier route since all you really need to do to make it work is put a fuel regulator in it and different throttle cable(if that) and a shifter cable. If you go from 4 cyl injected to 8 injected you need to put a 8 injection harness and all that jazz that goes with it. I dont know aboot you but I sure like to test my stuff out as soon as its done and im impatient. in other words GO CARB and like said before if you maintain a carb and get it set up right, its just as good as efi. and it puts that extra umph when the secondaries open up!
