Once you get the calibration right on the carb, you may want to reconnect the vacuum to the ported side of the carb, then work on the vacuum canister to slow down the advance rate a bit.....
The cam you have was used by G.M for 20 years in 305s and 350 and is a
easy to live with but has been best described as a "LAZY" Cam.
My Engineer recalibrated it and set it up with another 4* advance on
top of the Comp cams grind and that made a difference down low but cost
a bit on top as expected..Later I swapped it for a 222/222..450/460 GM
cam which is a mild cam & increased the Rear wheel torque by 155 lbs max.
My 355" had 195 TFS heads and 10.1/1 comp with 1.5/8 headers into a
2.5" system after collectors. Holley 600 with 6lbs fuel pressure+ 38* Total
advance. [10* static.] All the best with the project
