I'm relatively sure you DONT want to try this system on anything but an open header, gas ported, race motor. I've never had it work decent on anything else. The backpressure kills the vacumn needed to make this work.

do you think the pressure in crankcase during high-rpm ,with Lt5 engine say 427 cid+Turbo will be same as stock lt5??
engine like low pressure build-up in crankcase! more pressure=more heat!
less intake charge contamination!
