So, I have to know........ (solid vs hyd)

You fingered me. I changed from solid lifters to hydraulic in my '65 273 though kept the adjustable forged rocker arms. However, wrong to assume everyone on FABO wants a performance engine. Not me, though 99% do.

I had to replace the cam and lifters anyway. I switched to hydraulic because of much better cam choice and I didn't want to adjust valves regularly. I have done so way too many times on my 69 Dart 225 and Mercedes diesels, and have much better things to do with my limited time. Also, with hydraulics I could try Rhoades lifters which may increase mileage. I am probably giving up some high rpm performance, which is the 273's forte, but I don't plan to scream in my street driving anyway.
