Re: Motor Oil

I use Comp Cams break in oil. I talked with Comp Cams and the only difference in their regular oil and break in oil is the levels of zinc. The break in oil by the case at Amazon is typically $63.99, I'm not running a catalytic converter, so I'm comfortable just sticking with the break in oil. I've got close to 7K miles on my rebuilt 402 with no issues. This can be a touchy subject for some, so this is just my .02 cents or in this case $63.99.
