Well i am looking into doing some changes this winter to the car and have came to a crossroads on which way to go.My car visits the Track Very often know and still performs my daily driving duty.Right now my car has Tqv2 cam,Full exhaust,Gears,BBk intake,Ported heads #853,Bolt ons. Either option is getting topped with A ls6 or Fast intake and matching Tb,Because my tuner really does not agree with The bbk intake.

I would really like to be around 420rwhp,and i chose the 5.3 heads for better compression and they should also help with bottom end and torque compared to the ls6 heads .Correct me if i am wrong

Option#1
PRC 220cc 5.3L Stage 2.5 CNC Ported Heads
Tsunami camshaft 235/240, .654"/.609", 111 lsa
2000-6600 RPM Power Band Should be very nice for street/Track


Option#2
Keep my current cam Tq v2 232/234 .595 .598 112.0 lsa
PRC 220cc 5.3L Stage 2.5 CNC Ported Heads

Also i figure i am around 375-380rwhp now with the ported heads,I have not dyno'd it since the install of them.Also how do you think the high lift on the Tsunami would be for a Driver

id say option 2. i dont know if the cost for another cam swap is gonna be worth the gain. your better off keeping the torquer 2 and just adding some heads.

well i will not be out much money out all if i do decide to change the cam with heads just the cost of the came itself i already have springs and pushrods that can support about any cam i choice.

Definitely not option 1, I had a 2000 WS6 with boltson and a futral F11 cam 228/230 and I dynoed and average of 390 rwhp.
