19lb or 24lb Ford injectors
I have a 91 xj 4.0l with a k&n msd ignition e3 plugs borla header and exhaust crane camshaft and bored 30 over. I wanna upgrade the injectors but I'm not sure if 19lb or 24lb would give me better performance. Any info you guys have would be great

XF2E-C4B is the "stock" type replacements, found my set in a Freestar van (transverse V6 sucks to work on). Go bigger if you're going to stroke it. No performance gains with any fuel injector replacements on stock 4.0s unless yours are filthy and clogged.
EDIT: nevermind didn't read the "bored" bit. Yah contact Programbo
