[ZR1] Mods on my LS9

Mods on my LS9
You tell me guys, here is my mod list. AR headers that's ceramic coated along with x pipe, LMR ported sout and throttle body, 85 lb injectors, Griptech 2.35 upper pulley , DSX aux fuel pump, LPE 4 inch Cai, spec 3+ duel dish clutch. Cooling goes eldelblock intercooler, bricks by Kong,and tuned by Kong performance.I had a LS7 that sound great and ran with 520 rwhp but I hated to drive it. It surged at 55,65 no matter how it was tuned. I grew to hate it because of this. My zr1 runs down the road great, non of that ****. I am putting down 739, 742 TQ to the wheel with right fuel. I want a cam but don't want to screw the drivability up like I did before. What's a good cam to use that won't do this. Maybe leave it alone, I have pretty good numbers as is.

Unless you are trying for every last tenth of ET at the track, or do lots of 1 mile pulls on the highway vs 1000+hp cars, I'd leave it alone. I may be wrong, but I think those are excellent numbers with your current mods, especially with the stock cam.
There will be lots of good advice on what cam to run, but since drivability is extremely high on your list of "must have's", I'm not sure I'd mess with it.

Leave well enough alone.

Since you are familiar with Kong, have him race port the supercharger and that should get you another 30whp and you won't be thinking about a cam. The driveability will remain the same as now.

This is what I will say about a cam. If you are going to do a lower pulley then do the cam. My car hits hard at idle and even if it was only worth 10hp I would still do it for the sound alone. You can lug my car in 6th or crawl through a parking lot and it’s like driving a stock car. The BTR stage 3 and GP tuning stage 3 are almost identical and don’t have massive amounts of lift of really aggressive lobes so you will not be changing valve springs every 15-20k miles like some of the others.
