If there was a Tri-power 351W intake it'll be rare as "hen's teeth" There is currently a dual four 351W intake out there though, look here: http://pricemotorsport.com/
There was a 351w tripower on eBay about a month ago. They never made such an animal, so the seller had one made. He took an aftermarket tripower for a 302 and cut around it, removing the port flanges. Then he took a donor 351w aluminum intake, cut the center out, leaving only the flanges and enough port to reach the extracted center of the SBF intake, and welded it all together. It turned out pretty good. Looked like when the intake was installed, you probably wouldn't notice all the welds from the surgery. He wanted a pretty penny for it though. It didn't sell. If I can find the auction, I'll post it in case anyone wants to contact the guy.
Me neither, and I've been drivin em for a living. 31 years. Your flag has a ring of truth to it now with our new Communist in Chief Obama.
