Is multiport injection worth the extra cost??

[Keith58]

Hi
Like many others I am considering a switch from carb to EFI as being based in Scotland starting a Ford 418 stroker in the cold when it hasn't been used much can take a long tome to get to smooth idle.
I have actually purchased a Holley Sniper stealth kit but various advice including this forum suggests that multiport is the only way to go.
Problem is that setting up MPEFI on an older Ford V8 is VERY EXPENSIVE and looking at around £14000 ($11000) for a set up comprising the whole kit.
My question to those that have done it is pretty simple - although MPFI is recognised as the best does a TBI system such as the Holley do a good enough job??
If the answer to that is yes would I be better going for the Terminator kit with separate and more flexible ECU?
My motor is a 418 stroker with AFR 205 heads, Edelbrock Performer RPM air gap and 780 cfm profuel carb with MSD 6al, Tremec TKO 600 and weighs around 2000lbs.
Any real life advice from experience would be much appreciated. Want to get the bast from the car so if MPFI is the way to go then so be it but £14000 is a lot of money......
