Brad Penn Racing available at your local speed shop and its pretty reasonable plus its for Flat tappet cams. You can start a 1000 post reply on oils with zinc and just get confused. Some people will say Mobil is no good??? Brad Penn is made for Flat tappets so I use it
I have considered the roller but lots of things to fall apart and expensive plus the bronze distributor gear.
I went to a bigger flat tappet lunati and increased lift with a set of 1.6 roller rockers. 1,,2,3 and i was done and running again
