See the title. I want to put a 88" big bore in my 07 firebolt. I know I have to bore the cases and that's no problem, I have access to CNC equipment. My question is how much more torque can I get with the added cubic inches? Thoughts?
 
thats with cams, heads, hi-flo, race pipe, and prob race tuner and hi-perf carb
