Anyone have any experience with the Mass-Flo aftermarket EFI? It seems like a nice setup, that uses Ford EEC-IV electronics along with an LS1 maf, 1000cfm throttle body and Victor jr intake. Just looking for some feedback from those who have (or knows someone who has) this setup. Thanks.

 

Would work well for a Mustang, not sure about torque for a truck.

 

"Would work well for a Mustang, not sure about torque for a truck."
Thats one of the issues I was concerned with. I've always stayed away from single plane large runner intakes when used with a carb on the street, but the Mass-Flo website says that since it's a now a dry intake and computer controlled, it isn't as much of an issue. I understand the longer runners of a mustang or F series EFI intake would make more torque, but after reading all the "positive" write ups on the website and magazine articles, I figured I'd try to get the straight scoop from those who are familiar with it and not trying to sell one.

 

Well, 1000cfm is a bit much for a basically stock small cubic in engine. The 5.0 Mustang flows about 585 stock.
The short runners will kill low-end torque needed for a heavy vehicle I would think. I would use a truck Performer manifold if you are keeping the rpm below 5500.
