408ci build opinions?
408ci build opinions? Alright so I am about to start ordering parts for my 408 build on my 02 SS I just wanted to post on here to see what you all think and if you have any recommendations at all.. I am completely open to any and all opinions that you have! I will start by saying what plans are for this build/how I want to use it then I will give a parts list. I plan on using this car for street/strip mostly street. This year I plan on running highest compression possible with the piston I chose (10.6:1) achieved by milling my 241 heads down to 58cc or so and running around a 150-200 shot of nitrous (when needed). Hopefully in at around 500 rwhp/tq on motor and 650rwhp 700 rwtq on the bottle. Then next year if budget is right I will be swapping out heads/cam to some PRC 247cc heads with 68cc and lower my comp ratio down to about 9.4:1 for forced induction turbo/supercharge (haven’t decided) running around 15-20# boost looking for anything north of 800rwhp/tq.
