Coyled- I wouldn’t be surprised by the cam similarities if we were comparing all-out race engines. But, I must admit I was more than a little surprised by ProPower’s choice of cam for my street engine. When I told them my plans for the engine I said I wanted a pump gas street engine that wont embarrass me at R&G (my driving skills would provide all the embarrassment I can handle
).
I’ve got 2000 miles and so far no lifter failures or weak valve springs. I check lash frequently and keep a chart on changes to each valve. I haven’t had to adjust more than .002-.003 total so far.
RRD- Your right no cast cores or small base circles; billet only. The only thing that really concerns me is the lifters.
