After researching and researching I have decided to get some opinions.. After the winter I am planning to do some serious engine mods to my 102K mile 3800. This car was my daily driver, but it now more of a "weekly" driver, as I own two vehicles. I no longer drive it in the winter, however I do drive it a lot throughout all other seasons.
What I'm looking to do is build a good, street-able car that will be reliable and retain decent gas mileage. Over the months I've contemplated between doing a cam vs. an intercooler (or both), but now after researching I am seriously considering going cammed and doing heads at the same time with NO intercooler.
I am leaning towards the S1X for a cam, but now need to decide on heads... As of now, I am looking into vendor heads as opposed to local machine shop heads. The thing is there are so many different vendor heads out there. Obviously I would not need any stg4 heads with 130+lb springs, but what about stg2 heads ZZP or Intense? What about CNC heads? Which rockers would I be able to run with an S1X and the heads mentioned above? 1.6, 1.7, 1.8?? Any suggestions.. Again these are just "plans" for now. I want to learn more and make the right decision the first time around...
This is what I have envisioned as of now:
Intense stg2 heads with 105 springs
S1X with maybe 1.7RR's?
Gen V starting with a 3.4 then maybe a little lower from there
42.5lph injectors
N* tb
New factory GM timing chain/dampener (would I need a double roller?)
All other supporting mods and a custom tune
Looking to make 300+whp.
