Is it reasonable expect a smooth idle, or surge-free idle/low RPM cruise with a cam that big?

Rough idle I expect, but I should be able to cruise on the highway without noticeable bucking right? Originally Posted by Injuneer

Depends on converter/gear/rear gear. My car would buck if i was close to stall barely any throttle because of the cam Originally Posted by kgkern01

Rear gear is 3.73 but with M29 transmission, so 6th gear is more like having an MN6 with 4.24. Still get the bucking/missing around 2k as well. Originally Posted by Tubby Z28

Update: Cylinder deactivation test all the cylinders were pretty close, nothing stood out there. Went back to the tune and decided to adjust the BLM MAP table, as it was still stock, bumped it up to 50/70/80, and ran VE Master through it again, and it made a huge difference, it's actually driveable on the highway and cruising now. So I guess my BLM MAP table was the main culprit.
