I did mine in my garage , but you should be OK in the basement. If you are not living with a significant other, you can do it in the kitchen. Although I have no REAL proof, I don't think the X-Ram can out power my home ported stock manifold. At least not on a 350.
well if you wanna port your manifold ive read in a # of posts that an air grinder is much easier and faster. go to this forum and look around lots of good info on what ya wanna do including pics of what to port.
The ported Crossfire intake is the way to go. The x-ram will cost you much low end with a small gain in top end power-that's the simple answer. Even if you add rockers and cam the ported stocker will work better. Use the crossfire forum noted in the previous post and search and read the threads. The tech section will show what to port. It's time consuming but very worthwhile.
Crummy part is,nobody will put the extreme effort into making the CFI intake work,they just skip to a X-RAM. I did at first on the stock 350,actually only gained 10hp at most. ET didn't really change. $500 down the drain and a lesson learned. Other crummy part is,the X-RAM has proven on a few combos to run mid 12's at the track.
If the effort was appiled I believe a ported stocker can support a 383 and 12's. This is just me though.
CFI-EFI has a good example of how well a ported stocker can perform on a stock long block 350.
Is the X-Ram better then just taking my dremel to the original L83 intake manifold? If I do dremel it, where do I do it at?

Match the manifold ports to the head ports. Better yet, match both the manifold AND head ports to a gasket. Make the port runners as large in cross section as you dare. Be wary of shortening the runners as that is where the torque comes from.

Wouldn't the Xram with some larger throttle bodies be the way to?

my understanding is on a stock 350 larger throttle bodies dont do much good at all. bigger throttle bodies are generally used on bigger hp motors. and the x-ram does do pretty well with bigger cid engines and a ported stocker does rather well there too.
AFTER I installed and documented the performance of my home ported stock intake manifold, installed TBs bored to 2". I documented that there was no further performance gain from the bored TBs.
