As many of you already know i am doing a 5.4 swap in my 99 GT. I just spoke with Terry and Bob at Street Lethal Performance about having them assemble at the very least a built short block for me. I will be going with 4V heads on this motor and i want to build a bullet proof motor that i can eventually put an F1A kit onto sometime in the next year. so far we discussed some options for forged internals and even tossed around the idea of boring it over .20. If anyone has any type of suggestions, experiences, or comments im all ears. Im looking to get this done sometime next month.
