Again, how did NASCAR allow the C3 head?Warp Speed wrote: ↑Wed Oct 10, 2018 4:47 am I still can't believe they allow valve rotation in the inline class.....
Nothing "inline" about a c3! Lol
Here's the actual rule:
†Inline Valve/Non-Canted
Inline valves and OEM intake/exhaust architecture. Non-canted but not inline (e.g. 409 Chevy). Valves do not
have to match OEM angle.
