Is this a good cam for my 416 stroker

It all sounds like a nice street set up with the ability to make a decent track run.
IMO, what "I" would do is just run the combo as is and then after you know it a little bit, then go and make a change. First change I myself would do is the larger carb. It is the cheaper and easier part to purchase and install. See if you can not borrow one before you make the purchase.

If you feel drivability is good with the converter you have for it, the. Leave it in.
