Hi I own a 2000 ls1I have a corsa extreme exhaust,variram cai ,kooks ss hdrs highflow cats,and a 223/227 112 comp cam my dyno numbers are 363 rwhp and 342 torque vette has great drivability and very fast some people say the numbers are low and some people say they're right on I've had no issues .

Those numbers are right inline with your mods-----Right now your limiting factors on HP are --your heads and your intake manifold----
My 1st choice for your next mod to allow your engine to make all the HP it can---would be to install a LS6 intake manifold---Your stock LS1 intake cannot flow enough air to accommodate your mid range cam--You can find LS6 intakes cheaply these days and it would add an easy 12-15 RWHP-----Next mod would be to install some better flowing heads--On my 98 I bought a used set of LS6 heads for $600 and that mod added another 15 RWHP with a cam very similar to yours---

Hi thank you for the reply yes a ls6 intake is my next move it was suggested to me to use 0w 40 oil instead of 5w 30

I would stay with Mobil 1 either 5w30 or 10w30
The LS engine is notorious for oil being sucked into your intake manifold via it's PCV system----Installing a "catch can" is a mod that most all Corvette owners do----It practically eliminates the oil injestion--- Oil in the intake is not only bad for the engine but contaminates the air charge causing a loss in HP---Do a search on the forum----They are only like $150 and an easy install---I am guessing someone recc 0w 40 as a band aid to installing a catch can---
PS: when you install your LS6 intake get a flashlight and look inside your manifold---- I'm sure it will be dripping with oil and you'll see what I mean !!
