EPS cam. Keep VVT. Stick with Camaro intake. Long tube headers and good supporting exhaust system 3.5" or so single. Perhaps a CNC through the heads if you want to go that far. You really REALLY need to replace the 8 AFM lifters so the heads have to come off anyways might as well port them.

Match these parts up nicely and you should be in the 475 rwhp range

After re-reading your initial post I see you want a lot of bottom end. If this is your main goal to make a stump puller then do everything I suggested above but drop the exhaust size down to 3" single ( I think its 3" stock anyways ) and run a much smaller cam ( probably end up in the 410 whp range ) but she'll haul the bacon mighty hard. Contact PatG and get a cam spec'd you wont regret it. You can do that by clicking
