You need a lot of pump and injector to run E85, a lot of folks running E85 are running 1600cc injectors at a minimum. Anybody running straight methanol is usually at 8 1600cc injectors, but that's a different ballgame.
The 255 is a lot smaller than 255 once you start talking about big boost, but if its rewired and on a 1G its still in the 240 l/hr range at 15psi. I know Walbro doesn't recommend running the 255 with E85, but I haven't heard of any problems with it. The 1000's you have should be enough for 350hp at the crank you're talking about. You will have to at least buy another 255 pump and run the two of them or buy a nice Aeromotive external pump. I'd also upgrade the fuel line feeding the fuel rail. Is there a particular reason you're running E85? 350hp at the crank should be pretty easy to obtain on straight 93 pump with the headwork and cams you have. -------------------- Eric Wort
