I’ve left late in the day and driven to Summit, arriving just before closing to get parts so I would have them the next day. This build has been almost 4 years in the making. The 150k 318 Mag is stock (not rebuilt) except for the cam, timing chain, injectors and valve springs. Everyone said I couldn’t put more than 8 psi on stock pistons, but in October I hit the 318 with 20 psi.
