The stock rear is stout when you get the G80 out of it and put a heavy rear cover on.

 

Wow- really? I thought fer sure at that point you'd be hunting down a 14 bold SFA from somewhere..........

 

Actually I am, but I'm gonna try the ol' 10 bolt to see what she'll hold!

 

as soon as I find a car manifold ill dyno them back to back

 

I currently have a car manifold and just purchased a L92 intake. I'll be doing the swap and dynoing in a couple of months. Got too much stuff going on right now to do it.

 

I'm still trying to find a good deal on a car intake, so I can do this myself. If any of you guys have one let me know.

 

How would 14 bolt rear replace 10 bolt? Width and wheel bolt are different!

 

From a 2wd Silverado SS................

 

I did some searching, and Richard flowed these intakes way back in 2007. To my surprise, the car intake exceeded the truck intake at every lift point. It was flowing like 40 cfm more at .600" of lift with the intake attached to the heads.

 

Sorry for bring this back up, Alivn (PCM4LEss) just did a dyno on his 6.0L L92 head setup that he has on his TB SS. He posted the dyno chart on tbssowners.com but the L92 truck intake made 10 hp and 10 ft lbs of torque at the wheels over the car intake.
