Flipping the bolts was actually not intentional. I couldn't remember how they were before, but guessed they'd have threads pointing down instead of up
. Turned out better I guess.
Not sure on the power. I'd guess around 375-400 or so once dialed in. Back with the TPI I think I managed to get around 14 MPG highway, so I'd like to see 17-20 with this setup and a change in gears, but that's mainly a stretch goal. An LS would make a bit more power and probably still be more efficient especially due to it being a roller setup, however I already had this motor and the aftermarket heads, and wanted to do something unique. At some point I may retrofit a roller into it, or build on a roller block assuming the heads would still work.
