I plan on installing some HP S292 SC Cams and dual focus pumps in my cobra fp set up. My tuner is 212 miles away do you think it would be safe to drive there?
What are the cam specs on that? Is it 292 advertised duration??
For those that are saying it isn't safe, I would challenge them to explain why.
Here is my reasoning for why you will be ok. Assuming the cam install was correct and everything mechanically is fine, the cam does nothing to change the MAF reading. The MAF still knows just as well as before the cam swap, how much air is going into the engine. Now insome cases, it can require some tuning to adjust the injector timing to keep the from spraying on the back of the intake valve, but this is not something that would likely effect the a/f ratio during closed loop since the EEC will adjust to it. This is easy enough to find out, just drive it around for a while before going on any trip. If the a/f is too rich or too lean for the EEC to adapt to, then it will throw a code.
Thats what I'm thinking but wanted others opinions.
Yes .531/.531, 292°/292° 114° lobe sep.
More then likely it will be lean and have some idle/drive issuses. Other than that,if you can deal with the driveability glitches you'll be fine. You could also have your tuner send a file to help with it some until it gets tuned.

Yeah you will be fine, especially on that LSA which will help the idle. jstreet is correct, your MAF will still know how much air is entering the motor. Sure WOT and idle are going to be a little rough just dont go WOT. But you are not going to hurt anything. WOT is where the majority of your tuning will be anyway, so just take it easy and you'll be fine.
When I was putting together the 396 in my 97 Camaro drag car two years ago, I had a 256/267@.050" solid roller camshaft that we had just put in. I drove all the way from New Braunfels, TX to Houston, TX (about a two hour drive) and I had absolutely no problems.
I am assuming you have already checked piston to valve/cylinder head clearance?
