Another dumb question
I know this is going to sound dumb but I believe a dumb question is one that you don't ask. If you go to my racespace and look at the engine that I have as my default there are to lines on the intake (one on each side) that run from the front to the back of the intake......what are these lines for. I just recently got this engine (421sbc) and I have seen them on engines before but have never known what they were for. Thanks in advance for the help.
