    I am just full of questions

    Another question for you. I am beginning to perform a new combo for my car.
    It already has a tb bypass, p&p tb, 3200 convertor, magnaflow catback, lid, k&n filter, free ram air, 160 t stat, & custom tune for these mods. I am adding a cam, 228/230 581/588 w/114 lsa, long tube headers, custom y pipe no convertor, ls6 intake, ls6 port/shimmed oil pump, Zeks 175 wet kit, and most likely a set of aftermarket heads, TFS or AFR. Now for the questions, with these new mods will I need some kind of a fuel system upgrade, ie injectors, boost a pump, blah, blah, blah? 2nd question, what do you guys think of the TFS heads? I already know I have to run aftermarket roller tipped rockers & .100 longer pushrods with these. I am shooting for the mid tens, do I have enough AMMO? BTW this is my convertible we are talking about!

    With a good 60' time, you will run low 11s without your juice with H/C/I combo you are thinking about. Get the most 4l60e that money can buy, you will HAVE to have it on the jug. A 175 shot, if rated at the wheel (not sure what kit you are talking about) will put you in high 9 to low 10 second territory with a good 60'.
