The SRT-8 (6.1L and 6.4L V8)
I have a new forged 6.4 with 10.1 CR. I wanted 11.1 when I did build. I am being told that there won't be any noticeable power difference. I can only get 91 octane but usually have a race gas tune also. Engine mods are HHP custom grind can, new ported heads, 6.4 bes ported intake, long tubes...
