How noisy are the pistons at cold startup? Do you know what P-W clearance your builder used? <=> .0025"

******** A little slap which goes away pretty quickly with warmup. 'We' consulted with JE on this and used their recommendation based on the intended use (DD plus some track days) and on the skirt coating (JE "Tuff-Skirt"). I don't recall exactly where that ended up, but Ron at Outfront got a good discussion from JE, plus he uses JE on most of his builds, so I assume he handled it OK.
Hey Dean!
Good to hear from you.
How's everything going? By chance are you going to be at Pahrump? I'll be there...
