Hey Fred, those look like good numbers for the hyd. cams.
I know quite a bit about motors and cams so, it's just deciding on the type. I like rollers and Keith said the one's he uses, with
oil holes drilled in the bottoms, have lasted around 20,000 miles, which is a lot for our cobras.
We lash the valves on the sprint car every week but, having to lash the cobra all the time,....I don't know. I guess I'll ask you guys and Keith apx,...how often, if driven weekly.
I check my solid flat tappet twice per season.
