i just bought the stock 41-104 ac delco plugs, what go in the Zr1 and cts v...got them from rock auto...might be too cold for now but well see how they work...

 

How much boost do you plan to run?

 

i got the stock pulley now, after headers, i plan on downsizing...as far as boost levels, i was planning on you telling me what pulley pulls what...

 

What comes on it? 3.4" still? There are allot of variables to that, mine won't be the same as yours. Diff cam, CR, heads, headers, and I also run a 10%od crank pulley. Once you know where you are boost wise on stock pulley we can guide you. I am also running a phenolic upper manifold spacer and ported my lower manifold to port match it.

 

i do believe its the 3.4"

Im snooping around at boost gauges, i just cant figure out which way to proceed...i want a clean low key install...any recommendations?

 

I am not familiar with your interior to suggest anything.

 

Here's what I have: https://www.performancetrucks.net/fo...e-pods-478761/

 

There ya go, I see a couple that look discrete.

 

i have this one in my Denali

 

I like that, nice and clean.
