I don't disagree with anything said above, and was originally how I was going to do it.... but it was the guys at SC which suggested it... you could say... nothing ventured nothing gained...
Indeed, but I would guess that because the injection set up will ultimatly be acting like an electronic carb (like the SPI set up)/wet manifold arrangment then all the issues I detailed above are of less significance and less noticeable. Its still nice to do things right though. It would be intresting if you had the time and incling to try both set ups on the same engine and measure performance over things like fuel efficiency, driveability, and power.
