Built 5.3l 4v. Big cams 60lb injectors. Catless no egr etc. 02s hover around 1.0. Any of you guys get a good exhaust show at idle in certain sunlight or at night with headlights especially blipping the throttle. It's like blackish blue obviously the headlights seem to make it bluer. Leakdown is perfect, cranking compression is only mid 130 psi due too cams. But damn the emmissions this thing pumps out is nasty. Don't remember my dad's built 454 being this bad.
Stand behind it you smell like good ass the rest of the day. But the visible fumes concerns me at times. Anyone see what I'm descrbing.
Thanks
