Why so much inital timing???

It's fine. I run mine at 25*/35* 9.3:1 stock 360 Magnum, 234@.050 108 LSA. Car hauls a$$. If it ever wears out I'll put a better piston in it.
I'm sure yours runs great too, but if you need 35 degrees total under wot ...your compression is lower than it needs to be, and again...its not the best it could be.
