You can't slap a cone filter on the TB, we have an external MAF

Okay my mods:
3.5" with Velocity stack
180* T-Stat
1.9 Harland Sharp Rockers
Headers w/cat and exhaust on back
Autolite 605s (104s are too cold for us, unless you are below 3.4)
3.6 + timing

I did run a 3.4 pulley on that with a 1* of knock every once in a while
