Going pretty well so far. I'm pretty gunshy driving it though lol. Lot of moving parts, plenty to go wrong. I've noticed the belt creeping around on one of the idlers, so I'll need to see what I can do about re-doing the belt drive. I get a nice squeak every time I let off the throttle, presumably because the tensioner isn't at a very good angle. Hasn't thrown it off though. Fueling is a mess with that manifold....that's going to be a long process to fix. New power steering pump also makes more whine than I would like to hear, but its not as loud as the last one I pulled off. And it's silent at idle.
That's it for today's update, check back later after I've broken more stuff

Borg S594 on a currently stock LS3. I have a triple 12 for it to throw in eventually. The stock cam feels pretty gnarly right now though...excited to crank it up more.
And yeah, that hollow bowtie is worth some airflow. On the Gen 6 ZL1, the front inlet flow picked up by 9% with a hollow bowtie

Had an old friend from GM in town to visit and took him for a ride in the truck. Grabbed some pictures and Summit ended up positing it on their facebook page. Pretty neat
Been busy with holiday happenings but have been slowly working on things. Getting ready for the transfer case swap and prepping for one of the new Aeromotive brushless fuel pumps. One 10GPM pump to rule them all lol.

Lots of work on the truck. Lots of money spent. Not any faster.
T-case is in. Been slaving away getting the fuel system and supporting crap to handle the big aeromotive pump. Support bracket, surge tank, rerouted coolant lines. Ordered a Shearer Fab intercooler/intake manifold lid to replace the 417 motorsports IC because I missed where they got shredded on LS1tech for how poorly it performed. And also finally painted a few items that I rushed through initially because I was tired of working on it lol. I've come so far, yet still so far from being finished...I don't know why I do this crap lol
Yeah that's a cardboard mockup of my surge tank.
