@@@@@@@ 1 @@@@@@@
Background: Currently have a 5.0L with a Vortech S-trim
that makes 330rwhp. Has 80mmMAF, 30# injectors with
custom chip, Cobra intake, and 1-5/8" longtubes...
My (winter) motor mods are to replace stock heads
with TFS TW heads, new 36# injectors, reprogram the
chip, looking for a conservative 400rwhp all under
6000rpm for my roadracer.
Would like to add a new TB and EGR spacer.
What size 65 / 70 / 75 ? ...and why that size?
