I use Chevron Delo 400 for that very reason, as I want to keep my Carter 172 mechanical pump. I use the ARP bronze tipped one.
roller cams and mech fuel pumps
some time ago i had used a hyd roller (cast iron) and a mech fuel pump-i had to replace the cam when the pump lobe went flat-im getting ready to build a BB with a roller and mech pump, and now wondering if it was the same deal with flat tappet lifters and modern oils-lack of zink or whatever
i realize the pump doesnt have as much pressure as a valve spring/lifter on the cam, but wondering if it does create a problem, and should you use an additive like what they use for flat tappet cams
i know on billit cam cores they have the bronze tipped pushrod, and even a roller tipped one
any thoughts on this(and no i dont want an elect pump, lol)
