Sorry another 408 hp guesstimate (choosing Fitech system)

There is absolutely no reason that FITech wont work as well as a carb, power wise.It will work much better in many ways that carbs cant. It is not MPFI but you dont want that anyway. It should have the same tuning abilities as a carb. Remember, if using a 150 shot kit, it has its own fuel so it doesnt detract from the HP rating of the FITech unit. The 600 will be plenty. I would recommend a Tanks Inc tank with GMP-4 in tank pump and #6 AN feed and return line.

I have tanks, pump and line kits on special deal for FABO guys. A few members here work for companys that sell FITech and support them very well. Look in FI Tech thread to find them.
