That is the cam I'm running. I have the Pat Gold springs on it now, but I'm upgrading to the Pat Gold Extremes. It made 775rwhp at 6k w/14 psi, and at 7k w/16 psi the hp ws down to 650. We tried just about everything & decided it must be the springs (not enough seat preassure).
But I have a similar setup, 408, F1-C, Vic Jr, St III 317s, pump gas + meth, built 4L60 with a Yank PE 3400 stall, should end up making 800rw & run 9.5 @ 140 shifting at 6500....I hope anyway. Oh, and I have a 3750lb full interior TA.

I ended up going with a 242/248 .615/.621 on a 115lsa and shimmed my springs accordingly. Should have plenty of seat pressure. Start-up might happen this week.

Just realized it's been a while since I updated here. Everything is still going.
I drove the car a couple of times before I went back overseas for work. It felt strong but I didn't push it past 4500rpms because it was break-in mileage.
It put out 400/400 on the dyno at around 5,000 rpms before the bcm shut it down because the selective ride control hasn't been deactivated. You have to deactivate that when you put coilovers on a car equipped with that option or it limits your speed/throttle response.
The engine and entire drivetrain is coming back out next month. Engine is getting machined for 1/2" head studs and the 4l60/stock diff/half shafts/hubs are all getting ditched. Replacing with a 'Glide, built diff, 1000hp half shaft/hubs, and some other little pieces to keep it going straight.
Switched my choice of blower to the F1-R. I hope the new radiator and fans from Dewitt's keep things cool.

Long time, no update.
Changed direction, again. Twin TC 76, ptk style system is sitting at the shop. Still waiting on the 'Glide, halfshafts, rear diff and a few other things. AMS1000 sitting at shop as well.
The magnetic ride select has been deleted and the car went to the dyno N/A. Stock fuel pump couldn't keep up. Sold the headers to a buddy and the guts are getting dropped out of mine again for the swappage.
