318 driver - cam change or not?

An often overlooked cam on a bone stock 318 is a sealed power CS1006r. Single pattern, .420 inch lift, 204@ .050, 114 LSA. Tiny cam, rated for 1500-4500 rpm, this would work well with the performer or a Weiand stealth intake. An old Edelbrock streetmaster single plane rated from idle to 4500 would turn it into a real stump puller. Compared to the old TM77 sealed power ‘77-‘85 stock regrind of .394I-.420E and 196I-202E it’s probably the lowest step on the totem pole on the way up. But that’s just my $.02. With the performer intake I’d want to go a little larger on the exhaust duration, too, like the cam RRR proposed.
