Re: Rod Swap
I would say with the mods you have, a reg return and pump will not gain you any real hp.
Those mods are more of a 'supporting mod' to help you when you have larger injectors and the such. It will quiet the engine down some though, and since you want to go with more hp, yes, it is logical to do the fuel system. But I would say you have enough fuel to power what you got now, and even with a fuel system, you still wouldn't be pushing your PMR's...
