FWIW, it looks like this is the OP's cam:
Hughes SEH3236AL-8
Hughes Engines

2800+ recommended stall on the TC

Hughes recommended valve spring is their 1129 on their cam card. Dual coils, no damper, taller to be used with Edelbrock heads. So that basically sounds in line. Seems like it ought to go well past 6000 with this. (Can't recall if the Edelbrock spring seats meet this requirement noted for these springs but probably does. "Note: Spring base must be machined flat on OEM heads. Both springs must set on the same surface." )

I have the HFT version HE3037AL, 230/237/110 lifts of .549/.571 with 1.6 arms. Great cam. I shift it at 7000 all the time with those 1129s on my Eddies, but with a lifter preload of just 1/2 turn, and all the oiling mods save for the crossover.
As a streeter, the 295 BFGs never stop spinning below the speed limit so... I can't tell where the power peaks exactly. So because it pulls the way it does, I just let her buck. With 3.55s, 65 mph is 5500 in second gear, and the tires are still spinning, so I really don't care where the power peak is,lol. Not bragging on the combo; jus saying, at 180psi or more cranking cylinder pressure, that's a great tire-frying cam.
