Man, if it were me, I would hold out until April and pick up the FAST LSXr 105mm intake and TB and have it ported. That will not get you to mid 10s but I expect it will be noticeable, especially given the L76 is quite a choke point up top. You may want to go to something like the TFS235cc heads, which could work as the new FAST is said to be compatible with both L92/LS3/LS7 heads as well as the cathedral port heads.
If you just can't wait, perhaps LS7 heads and intake, thoroughly worked, will get you there...? |
