Why so much inital timing???

Oh is that what he's runnin? I honestly didnt pay attention there........If that's the case, then I double down on agreeing with you. Closed chamber heads with .039 quench is good for 11:1 with the right stuff.



I just assumed this was regular open chamber crap.




RRR, like me, the OP gets his quench by sticking the piston out of the deck. Some people think quench can only be had with a zero deck and closed chamber heads. All bullshit.


Like I've said before, you'd have to have a damn good closed chamber to make me give up the open one. You want quench, run the piston out of the hole.

This also reduces crevice volume. And that's a big deal.
