Thanks. I was planning on calling Howards and Hughes Engines when I get more information after tear down. Also considering Jones Cams. Hughes claims to have a better lobe/ramp speed setup for the Chrysler engines designed around the 904 lifter. Hughes also mentioned having some "Stiffer" than stock lifters in the 904. Any experience with Hughes in this aspect? I may also consider the solid flat tappet. I wasn't sure about using a solid for street application and I don't have much experience with the solid lifters (Except for setting lash on an old VW bug) my wife had 30 years ago.
I ran Sealed Power hydraulics lifters in that SBC. Put a lot of hard miles 100k ++ on that old 73 Nova. It was my daily driver as well. Hard, I mean drag racing folks with several 1/4mi runs every other weekend but I was only about 18 or 19. I'm sure it was nothing like folks on here do but to a kid it was a big deal. Oh what memories!
