check your timing.. if it's anything under 25 knock it up baby! hahaha.. if you disconnect the tvis, it will disable itself, and stay in the open position.. some people say on a stock motor with minor mods it's best to keep it.. but i have just put a bigport into an 86 with tvis butterflies removed, and it's quite torquey..
redtop.. meaning? 100kw smallport, AW11 bigport w/7 rib block?? little more clarification to what you were comparing it to.. cos my smallport motor walks all over this bigport one and it doesn't really have that much work done to it..
