Stand alone throttle body EFI systems

Looking at a few systems for my 1970 mustang 351c 5 speed project.

Who’s messed with any of them?

Pros? Cons?

Which system would you recommend?

It’s a 358” 351c 4v engine making about 450

from what I see holley has several. im wanting to do E85 on a blown small block. between the cost and the hassle of installation. im very hesitant. im running a mark sullens E85 950 on a roots blower. for the money its pretty spot on. BUT.. I left some fuel in it for a month and damn near destroyed everything. I want to go with a super sniper from holley. but noting is compatible with E85 as far a sitting for awhile goes. unless everything is anodized. id like to hear some input aswell.

One word, HOLLEY. The Fitech seems to be hit or miss but if you have any problems their tech support blows. I have a Holley HP efi and their phone tech support leaves something to be desired but they have forum on their website where you get super fast tech support and they have everything down to what the part number is on the pins for a certain connection of a certain harness. I have used the forum several times and always got helpful info fairly quickly. They also have a FB tech page which is another avenue. I have a buddy that is a Holley dealer but works/installs everything and he said the Holley has the most tuning options where as the other brands are pretty limited.

What I always suggest is to find a dealer near you or someone you can rely on for help. Some people like FAST some hate it. But another friend had problems with his FAST system and couldn't find anyone around to work on it when he could't find the problem (maybe he didn't try hard enough) but if you know you can take it somewhere close if you can't figure out a problem or need help tuning that can be invaluable no matter what brand.

Ended up grabbing a Holley Sniper set-up

I'm looking forward to it. I wanted to buy one for my Galaxie but I bought two 4150 throttle bodies for another project. What a rip off throttle bodies are IMO but I wanted them so.....
