Yep, that helps a lot. What pistons does it have?
The way your car is set up I think you would like the 112 version of that cam with RA manifolds better and the car would run a little harder, especially if you plan on a manual swap later. The 114 version with that much compression the idle will be closer smooth with just a hint of lope. Almost dead smooth if you have a X pipe or H pipe on the exhaust system. Like I mentioned I think that grind needs more exhaust duration when it is widened out like that. It become kind of lethargic after 112, it widens the power band out and ends up making less power. I have 423 with the 110 LSA for a 400 with 62s, it is fairly mild to me. Pretty similar to yours in a 557 block. 1.65s are a good idea.
