yep! Have Seb Scheduled for 2/13 for a full tuning visit. JMS did a great tune but there's nothing quite like having the "godfather" of all Z's having a look
The JMS Stage 2 Shortblock build included JMS Spec CP Pistons/Carillo Rods, ARP Mains Studs, New Main, and Rod Bearings.
Did have the Cosworth Head Gasket added during the build but again always like to get his input. I'll probably just bring the intake manifold with me and have him take a look at it.
