I'm rebuilding my SBC 350. I will be doing the fancy new cam (XE262) break in with Delco 400, GM EOS and Cam Lube. I noticed while reading my Hanes manual they say to pack the gears in the oil pick up with vasoline during reassembly. Is this really the best idea? Is it good to mix vasoline with all these hi dollar components during breakin? What have you guys done in the past?
