i have a LS6 intake mani now. would it be worth the $$$ to upgrade to a FAST or something better? or would the gains be so small that its not worth it?
not saying im going to do it just curious to see if it would even be worth it at all.
i may be swapping to a ls6 valley cover so i figure since im taking the ls6 off might as well put a better one on...unless it would be a waste of money.
thanks
Mike.
