yer i don't think the throttle body or head makes much difference though vince did say it seemed very torquey for a 2.8 it makes more torque at tick over than my abf made peak lol wether thats todo with the head i don't know?
oh yer forgot about my grant motorsport ported head, amd throttle body, 2.9 inlet lol i am going obd2 now though as they seem to make 10hp more than mine with less mods + plus i am turboing it:)
