Cam grinding

The cam in it is a 230/235 @.050 480,495, 1.5 rocker. 106 sep. Engine wont idle in gear. Idle in neutral is 1800. 2200 summit converter acts tighter than that. I have a Comp 292 cam 244/244 @.050 501/501 lift, 110sep. I got on trade and don't see ever using it even in my 340 for my 67 Cuda. I would like to try and make it useable. My third choice is a mystery cam that came out of the 340. No stampings on it. The lift measures approx. .418/.441 but I have no idea what the duration and separation is. The whole idea with the car is using parts off my shelves.
