I was expecting more, but I think that once you get it dialed in you'll be in the 12's with no more than the parts you already have on it. That is one beautifull engine with a very nice blower on top. With what I've found from that engine and knowing what I do about the TVS1900 (what I've learned from Brian and Joe) I'd think your shift points should be closer to 6300 or so. How much timing are you throwing at it? Those heads tend to work better with more timing the the previous cathedral port heads. What injectors are you running and what is your IDC?
