I have a 468 BBC. 13-1 comp, Merlin 345 heads, solid thru out. Cam is a Comp, .715 lift, lobe center 114., int dur 260., exh dur 272., timing 4.0. Running two Edelbrock 750 on Weiand Tunnel. The primary jets are factory and I went up two jet sizes on the secondaries. Timing is locked at 32.
Question is; plugs look good, light brown. But inside the headers are a very light grey. They are so clean you can see very clearly the four tubes inside.
Am I running too lean? I do not want burn pistons again!!!!!!!!!!
