Rocker arm recommendations?

Loving this "discussion." Back in the late '80s, working with a friend on a budget build of a 360 in his '71 Duster Twister (wish I had the car in the same condition today!), out of necessity we modified (ground) some 273 rocker bodies on the ball side of the adjuster boss to allow the use of the 273 solid pushrods with hydraulic lifters. This did increase the rocker ratio a little bit (as Jim said, moving the ball closer to the shaft centerline), as we measured the lift at the valve (with a shimmed-solid hydraulic lifter) to be close to .480" when the cam (an ancient Crane Blazer or Fireball grind) was advertized just under .450". I was skeptical about the oiling and longevity of the modifications, but it worked perfect for my friend for many street miles and missed 4speed shifts and overrevs. A full 15yrs later, I was at a dragstrip a few hours from home helping another friend at the track with his Super Street 440 Duster and a guy there that night asked me if I wanted a "Muncie 4speed Duster drag car?" Went and looked at it, and yes, it was my friends old Twister, so I bought it! He told me they drag raced the car for years with a 5.12 gear, and overreved it many times and bent some pushrods. Being Chevy guys, they went to Super Shops and ordered pushrods for a hydraulic/adjustable rocker LA motor. TOO SHORT, LOL!! So the guy said they had to buy "custom" Erson pushrods, but they are really shelf mechanical pushrods, hope they didn't pay a premium. The rockers, shafts and adjusters looked so good, I reused them in a 367 I later built with some maxxed out J heads and turned 7000rpm regularly with a .508" hydraulic cam, and the measured lift at the valve was right at .530".
