Well, I'm at that point where I probably need several days to pull the console, make the mods it needs, do the body work and paint and reinstall. I had the chance in early Sept. but didn't do it. I'm going to try again here in late Oct.
2 of those PPI's will need close to 1.5 cubic ft of air. That's a fairly large box (about the size of the one in my worklog). You'll have your hands full trying to integrate that size box into a factory EX console. Put on the thinkin' cap, where theres a will, theres a way. Maybe only use one of them, or put all the PC stuff in the console and the subs elsewhere? Space management will be key.
I had a 95 2500 ECLB 2x4 with a 454 in it. I loved that truck. I had a 92 prior to that with a 350CID. Great truck but a little shy on power for towing however it was impossible to break!
BTW, I'm looking forward to seeing the *** end of your truck painted. Love the work you've done there!
