I also run twin 255's in my green truck and it seems to do well

 

I don't imagine you are using the factory fuel lines and rails, so what size line did you go with with the twin 255's?

 

While I can't speak for the 2v motors the 04-08's came with large enough rails and lines to support 750hp. You may be fine.

 

stock rails and lines, they will handle the power you want, but ensure your rails and lines are compatable with the E85

 

Thanks to everyone who had info on this but my plans have changed. After talking it over with the wife, since Ive had my drag car I realy missed a street car so I am going to do a stock rebuild with good rods, more boost and a custom tune on the truck (because it needs a rebuild anyway). Since Ive conceeded to this I also get to start looking for a street car. Im going to get the first real muscle car I owned out of highschool, I should have never should that car but we all do stupid things when we are young. Ill be looking for a 1970 GTO by next summer.

Again thanks for the info, sorry to waste everybody's time.
