Ahh, yeah, relatively speaking when you compare it to the rest of the TA cams. It is towards the top of the list. Isn't that typical of all timing curves at the time? Advance doesn't max out until 4000 RPM or more?
But how does it compare to a factory cam? Factory cams were 194*@.050" for the intake, low 220's for exhaust for a non-Stage 1 cam. Comparing "advertised" means almost nothing because the factory cams were measured at almost nothing, .002" or so. I agree, very few "fast" timing curves from the factory except in HiPo land like the Stage 1 and even that was way slower than anything that you would consider fast. The factory was very adverse to ping coming out of those cars even when running low octane gas. Some of those springs looked like they could hold the front of the car up. Earlier DCR came out at 7.48 which seems fine to me. However I won't argue that putting in better pistons is the way to go. Speaking of pistons, was the current rotating assembly balanced with the 392 pistons?
Factory cams were itty bitty for sure. I am glad to see the OP go to different pistons, it wasn't Too Late.
Ya, relatively Mike... I consider "Performance" cams to start in the 226@.050 duration range on the intake. Typical cam that goes out of here in a mild street motor is at least 230@.050 on the intake, and I am sure the cams in the examples given were considerably bigger than that, considering the performance of the engines.
