I would never put another one of those flexplates in my car regardless of who thinks they are good. I ran a 1000 hp drag car with a transbrake and never broke one like that, especially on a street car with no load on it.

So these arrived, Peyton's covers are super nice but triple the cost. These look really nice along with the welds, I like the short outside edge. The baffles look good and they fit 1.25" grommets. Similar height to stock covers but gain from the shape and no recessed gasket ledge.
Those look really nice, but being nearly stock height will they clear a high lift roller valvetrain with true roller rockers and poly locks?
I bought 3/8” tall aluminum spacers to make sure my chromed ‘74 only covers will clear my Harland Sharp roller rockers.

I had the same question. They've got very affordable valvetrain oilers that would also provide the necessary 3/8" height on a Chevy, but have never looked for some to fit Olds.

74 only? Do you mean the 73 only Oldsmobile script covers? I have painted Oldsmobile script valve covers on the 350 currently. I compared the new covers to the aluminum Edelbrock valve covers without baffles, which are marginally taller to a set of 260 valve covers on my shelf. The new aluminum valve covers are a good 1" taller than stock valve covers, on the edges, even more. They should clear with ease and look good doing it.

Ok, so I installed the the Transgo 4L80E Transgo HD2 shift kit. The good, it comes with a new seperator plate. You do have to drill two holes, pressure relief and you actually add a spring loaded pressure relief valve and plate to the actual valve body. New bigger boost valves, stiffer springs, not only for the line boost but for the accumulator overall and 1-2 and 2-3. The bad, it could have used a 1-2 accumulator O ring, since it needs removed to change the spring. Mine was stretched, freezing didn't help enough and actually caught and pinched itself. It seems to do the job sealing, still but may pick up a sealing kit. There was a small bit of dirt or clutch material in the pan and the valve body. I used a shop vacuum then carb cleaner and rag to remove the drill shavings and dirt. See if it is any different. Was barely noticeable part throttle and firm at WOT. I set it at the base level, tweaked with accumulator springs, two vs either one large or small for firmer and very firm.
