testing to see who may has tried it.. im looking to maybe try some tfs heads on combo from my 317s i ran this season with good luck. i run a stock rocker with truniun upgrade now. my changes if do are to run a short travel lifter (hyd) over stock lq9 i had, and run 170 seat pressure a little above the 155-160 i had this year as well.. current combo went 5.54 at 128 1/8 at 20 boost.. seeing 7200-7300 rpm. some say i may be pushing it with stock rocker oh and crank, but im trying to see how fast will it go. i plan added boost if needed as well this coming season. i guess if anyone has ran a tfs with stock rocker set-up, im curious was it as extreme as what i may be getting into for the need to go too a shaft mount and be done? thanks
