I have an excellent condition low mileage LS6 intake for sale that already has had the ribs ground down on the bottom to clear LS1 coolant tubes. The only reason I am selling this is I got an excellent deal on a FAST 78MM and ported TB, so it has to go. It's $375 shipped FIRM so don't ask if I'll take less. They've been going for $325 - $350 on eBay PLUS shipping which in some cases is $40 so this is fair market value for this. Not only that, but you don't have to waste your time grinding the bottom to get your coolant lines to fit. If you're interested and have paypal, send me a PM. You may not be willing to drop $375 for it, but the next guy will. Just thought I would offer it up here before it goes on eBay.

 

Sold!
