EFI question
I was leaning towards the Hotwire setup, but I reckon the EFI source kit is looking pretty attractive. Pretty much anything is going to run to about $2K give or take a few hundred, that seems to the market price.
Holley, good and bad is the modular harness, you basically need to buy 3 separate harnesses, main, coil and injector, more flexible I guess, but adds to the base cost. They also offer a drive by wire harness if you want to use that option.
EFI Source, base kit seems very complete, just need to convert to cable operated throttle body, not a bad choice if you are going to run an old school auto where you need the kickdown operational as that is one less thing you need to deal with.
Hotwire is good if you are running a stock 5.7, anything else you will need to buy one of the diablosport tuners, which all adds to the cost.
