Hey guys, I've installed a GM RamJet 350 in my restomod/daily driver with a Tremec 5 speed. The rear is a Moser 12 bolt with 3.42 posi. My problem is I'm getting no support from GM Performance Parts on the heater plumbing routing for the 350. I may have this posted in the wrong place, but does anyone have some wisdom to share? Maybe a source where I can get some help? Thanks very much, Hugh
