ive seen alot of people saying that aftermarket fuel rails wont fit with a stock distributor. will the msd 8455 be high enough to use the new fuel rails. i have aeromotive billet ones(red)
It's a double edge sword. Most of the aftermarket fuel rails require that you change the distributer, but I think they are making ones that clear now. I don't remember which brand they are, but someone on this website bought a set. There are also more brands of distributors available now. It used to be that if you had to get bigger fuel rails, then you had to get an MSD distributor. You could then get more fuel to your engine, but the distributor failed like every 250 miles, so it kind of sucked. I've heard that if you put a factory pip inside the MSD distributor it fixes most of the problems. However, the stock fuel rails can support over 500hp, so most people just stick with them. If I ever need more fuel, I'm just going to duel feed my stock rail.
