And here we go again! LoL
Just finished building yet another SBC engine for my '77 Silverado. Its a 406, 4 bolt, Scat crank and rods, Comp flat tappet bumpy stick and Edelbrock aluminum heads. My machinist wants me to use either a "breakin oil" or a very high content ZDDP oil.
I'm not at all concerned with today's oils but he kinda sorts is. We both still build non-roller engines with not one cam failure between us yet. But the "so called horror stories" abound.
But anyway, are there any "OTC" oils that meet the ZDDP requirement everyone seems to want? Or a start-up breakin oil that's not $200 a quart? He uses Joe Gibbs oil but is currently out.
Thanks
