This is a 454, with a solid flat tappet. Engine fired up and the first shot :hurray: . Sounded great so I was keeping it at 2500 rpms then I started to noitce smoke coming from the header collector where it seals, also noticed smoke from the mufflers where they seal to the exhaust pipe. This is my third breakin and this never happened before, could something major be happening?? I had 80 lbs of oil pressure but the temp did shoot up to 220. Please help??
