The 6395 would keep costs even lower, albeit less gain on top-end. The Summit cam will carry decent power to 5,500 rpm and beyond if your short block is up to it, you have a decent air intake, headers and exhaust and you fix the ignition coil minimum dwell setting in the PCM that acts like a rev-limiter around 5,800-6,000 rpm. Advancing 4° will bring the powerband down ~300 rpm.
As I mentioned earlier, I would get a new roller timing set. The Cloyes 9-1157 is 3 way adjustable. Advance the Summit cam 4° to bring its powerband down to work better with the stock intake manifold. This is especially important if you still have exhaust manifolds and stock exhaust. Advancing the cam will also help keep the idle vacuum closer to stock which should allow it to run better with less tuning headache.
Summit has an advertised powerband of 1,500-6,000 on the 8800. Advancing it 4° will lower that to about 1,200-5,700 which is perfect for the 5,800 rpm fuel kill. Stock shift points are at 5,000-5,100. If the engine is solid and not strangled by the stock exhaust manifolds, I would not hesitate spinning it 5,500-5,700 rpm although HP flat lines around 5,200 rpm with a stock intake manifold and it just carries the same HP higher with more cam. When I had the stock cam I actually shifted mine early at 4,800 rpm.
