The B&M shift improver is a $.89 resistor in a plastic box with a switch, again garbage.
You need to be thinking headers, stall and gears before a cam. When you do a cam error on the small side rather than big, better to be left wanting more power than not liking the manners of a cam that is too big.
Lloyd/Bret Grind 1, 1.5, or myabe ver. 2
cc305
cc503
I would think a cc306 is at the max given the criteria. (A tune will be needed)
All these cams will make power, what you like can and probably will be influenced by other peoples opinions.

As for a better tuner DO NOT buy a handheld tuner. Wait until you do all the bolt-ons and get a mail order tune from pcmforless, madtuner etc. or just wait until you do all the bolt-ons and cam and have it dyno tuned. Handheld programmers are expensive pieces of garbage. As for the cam, get all supporting mods first, full exhaust, gears, stall, suspension etc. etc. before you rip into the motor. Without a stall it wont drive good and without suspension you wont go anywhere so thats the first focus. When your ready for a cam check out that the link projekt70chevelle posted will help you out alot.
On the B&M thing all it is doing is tricking the pcm into thinking line pressure is lower than it really is so the pcm raises it at all points.
You can accomplish the same thing with pcm tuning only scale it so that very low speed operation stays mild.
Far as tuning you can get an editor that you use through a home computer or laptop and learn to do it yourself for the OBD2, you can trust a professional, or you can consider an OBD1 swap and cheaper self tuning, this is a hassle if you have emissions testing though.
Tunercat has OBD1 and OBD2 options I find it unfortunate that they sold the OBD2 to JET but the right guy developed it so hopefully it is as good as the OBD1 version.
LT1 Edit I do not like because they lock it to one VIN meaning if your pcm locks up and you need to go to a spare you have a problem. Tunercat's support and pricing are much better too. Only plus I will give LT1 Edit is it is prettier.
