the head is restrictive,true,but as it is on forced induction this shouldnt keep the engine from reaching 6500 at least
zetec 2L bore x stroke = 84.8 x 88
lancia delta integrale 16v = 84 x 90
There you have it.. it's 16v.. so much better flowing....
As for the fuel..
It was rolling roaded and the co at max rpm was 9 so there's more than enough fuel imo.....
6500 for a zvh is verry high so i've heard.....
integrale 8v is also 84 x 90
anyway,are you also sure the cam isnt over advanced(mixture loss) or perhaps retarded too far.
-sparkplugs set at the right gap
-ignitiontiming right
