Awesome. I'm doing a 4.8L swap into my GTO, only using 243 heads instead to keep the compression up a little bit. Looks like LS6 cam is a solid choice. If this truck is in the 10's with this motor... I should easily be able to hit 9's with some work. Unbelievable.

Which year cam are you using? What part#? There are two of them so I'm curious on the specs.

You are still on stock bottom end right? Stock rod bolts? Mains?

Thanks

 

You want the 04+ cam I believe.

 

Interested to see what route you go. Truck sounds and performs amazing.

 

MSRP: $3,599.99 Ouch!

I was using 02 LS6 cam, not sure on the p/n. Now i'm using a Speed inc Tu1 cam, but the turbo isn't making much if any more power due to the restriction (turbo turbine wheel) in the the exhaust at this level.

Still OEM bottom end, 109k miles on it now.

 

Wow.... I can't wait. Can't believe the stock rod bolts are holding up to that abuse. I should change them simply because I always have a little less luck than everyone else, haha.

Thanks for the info. This is exciting. Good luck with the future mods. Please keep posting more vids. It was nice to see your vids without background noise or music. I found some on youtube of yours months ago, which is what got me wanting to try this block in the Goat. I wanted to hear the monster but there were always other cars burning out or something.

Beautiful build.

 

What do you spin yours to, Rob? RPM has everything to do with rod bolt longevity. That's why the NA LS1 car guys break them running 12s and we can run 9s with a turbo in a truck...lol

 

what about a twin set up?

 

Thanks the compliments Quick and good luck with the goat.

Smoke, I aim for 6.5k shifts. I'm usually within 100-200 rpms of that and fuel cut comes in at 7k.

 

I am absolutely amazed how well that motor is holding together for the punishment you are putting it through.

In for what your next move is

 

I think a S475 with either the 83 or 87 turbine and a 1.10 housing, T4 of course
