My stock stroke mild 360 build ;)

250 psi! I hope that’s a typo. Or you poured oil in the cylinders.
Not a typo... I just did another test right now. Plugs left out over night, engine cold, carb off manifold. 250psi in all cylinders.

it has a small cam.... engine doesn’t like any more than 10-12* initial timing or it’ll detonate. I only use pump 91 CA crappy gas.

here’s a picture, 1&2. All the rest read the same, my gauge is good, unless I’m an idiot and I’m reading the gauge wrong...

what can I do? Lol.

speed pro hyper pistons, .003 from top of deck, speedmaster 65cc heads.
