Yeah, finding a cam that's big enough to do some good and small enough not to have "issues" is a tough call. Plus one guy's too big is another guy's too small. My blower cam is a 224/234 116+2. I wouldn't want to go any bigger for a DD. I have "0" tolerance for big cam issues though. You may not mind "shifting around" some of the big cam issues. Not for me. Problem is that my cam a 460-470 rwhp cam without a blower. With 9.5psi, it's a 664rwhp cam though
Are you totally against adding a blower? Best of all worlds for a DD.
Sorry for being "that guy". But it's a Corvette Forum rule that at least one of us blower guys has to jump on a cam thread and recommend a blower. It is what it is....

what sort of issues are you talking about needing to shift around? It's in my plans to add a mild to mediumly aggressive cam for street and maybe a bit of tracks days/drag racing. I'm curious about what downsides I will dislike. (my car is a manual) will I still be able to cruise on the highway in 6th smoothly at low rpm?

If you have never been in a cammed car it would be hard to explain. Basically a good dd cam depends on the aggresiveness of the lobes ramp rate, duration, lobe separation angle, etc. Also what is your tolerance of what is too much or too little. The best advice is to talk to a cam spec guru and tell them exactly what you want and how you want it to behave. Clearly a good tuner comes into the equation as well. A cam that is too big for the average guy will buck and surge at low rpms below 2k and typically around 1.4k. The work around is to downshift and keep it above those rpms. Hope that helps.

Pitufina put it pretty well. Overlap is what you need to look closely at as far as I'm concerned. I've had a +9, a +2.5, -3 (current cam), and several more in the negatives. With the +9 overlap cam, I could tell if I was going against or with the wind. Against the wind, cruising at 60 in sixth gear was OK. Cruising with the wind, I'd shift to 5th because of the surging. Also, you see less than perfect manners going up and down hills in 6th. The +2.5 o/l cam wasn't as bad, but it still had a few low rpm issues. The -3 and smaller cams had pretty much stock like manners.
Again, it's a personal preference thing. Some don't mind that stuff at all. A spot on tune sure helps, but won't totally eliminate issues with a higher overlap cam. That's been my experience anyway.
