Ok so Roger Vinci handles customer service personally. Very helpful ,lifter on the way.

That's really good customer service.

Did You mill the 317s at all?

Also since it got a little more serious do you have a power goal in mind?

No milling , changed to lq9 piston and stock rods are 6.098 and new rods are 6.100 over 10:1 probably close to 10.5:1. No real goals but thinking with with cam,8.1 injectors ,1 3/4 primaries bbk drop in headers and black bear tune thinking maybe 400ish. More of a towing engine really.

That's a very similar combo to the 6.0 in my Tahoe. I tows extremely well for a 1/2 ton.

How about fuel economy?

 

[Dantheman1540]

It gets mid 15s around town but I don't get much highway time. The one time I did get a long distance trip in it got 18-19 at 75mph. I havent towed anything long distance yet but I would expect between 9-12. I'm kinda impressed with it because most people I know with a 6.0 in anything get 12 flat. My RCSB with a 4.8 never got better than 13, now with a radical 6.0 and blower 10mpg is the average and 6 is the best towing.

Right now I get 13-13.8 city about 20 at 60, 16 at 70 and 8-9.5 towing.

 

[Dantheman1540]

I don't think that's terrible for an XL with a 4 speed auto. Might get 1-2mpg better with the new combo. That's if you can keep your foot out of it.
