I'm getting close to having all the parts for the 2270 build, but have a few questions:
This will be primarily an autocross engine with some weekend drives. I also drive to events. The engine needs to be able to spin to at least 7500RPM even if it's not making power up there. Here's the rest of the config (all of these parts are in hand):

Not the thread-jack, but... @cgnj I, too, am interested in which shims you used. I purchased a 2270 Crank, P&C kit from AA and have the bottom-end together. When test fitting a P&C for deck height this weekend I see my cylinder sitting about 2mm _above_ the deck/proud. Therefore I assume I need a shim on the order of _one tenth_ of an inch (I'll precisely measure when it comes time to order, but I was just doing a sanity check). Couple of questions here:
1) I recall Jake saying using large shims requires lots of advance and is hard to tune, was that your experience? 2) I recall another forum member cautioning against stacking large shims, should you _not_ stack at this height? 3) Did you have this issue, and if so, which shims did you use? |
