Should I build up a stock ls6 for boost or find a 4.8 or 5.3 for boost? I think the extra weight will throw off the balance of the cts-v since it will be a car to take on the track (not strip). forged pistons and rods will go in regardless of lsx or iron block. I would prefer to use the stock ls6 block and boost to about 800-900 whp. if not then ill go iron block. Also I was going to go with a 3.6 or 4.2 PD SC or f-1 procharger. any input would be great. thanks!

An aluminum block will do just fine at those power levels, it's more the bottom end that you have to worry about but you're taking care of that.

Idk if I would do a big PD blower on a road track car, that thing will overheat real quick.

I know what you mean by overheating. What is weird though is that D3 only offers PD superchargers for their cts-v's...which is off since they are a real circuit racing focused brand...So is the procharger choice adequate? or should I go bigger?

Unless you've got a really open track, FI is not usually good for road racing. It's more about the setup than just raw power.

I would get a nice stroker kit for the LS6, build it up to run some revs and have a much more reliable car than one with a big procharger on it.

The centri would work better than the PD.

hmm. what can a cts-v with a stroker run in the quarter you think?
