Whats the best air intake mod?

[ZROne]

Just finished with the exhaust side of things, and am getting ready to do the intake (62MM TB, ported plenum/injector housings...) and was wondering if the ram air kits are worth it compared to just cutting open the lid?

Chris,unless you're referring to your 368",I would pass on the 63mm TB. The stock displacement LT5's really can't use the extra airflow. Jeal makes a nice carbon fiber ZR-1 airbox and the Vortex is interesting. Just my .02.
