I don't think there is a "right" or a "wrong" here, it is all about what you would enjoy working on and driving. I have a LT Camaro Z28 with a build stroker engine and I'm running the factory EFI. It is a fun car tp drive and I enjoy all the high-tech stuff that goes with it. Have you checked-out the LTXtech.com web site?
I also have carbed tube-chassis drag car and I really enjoy working on it and racing it.
