LS Motor - Cadillac Escalade
« on: Wednesday,September 04, 2019, 07:44:37 AM »
Hi Guys,
There was a bit of interest on Sofa King's thread about the LS motor.  My all aluminum truck motor is very similar, besides the wet sump and accessory drives.  Here are some pictures of the Gen IV L94 (Cadillac & Denali 6.2) which is an LS3 variant (Camaro 6.2L) and very similar internally.  The only difference that I have seen reported is that the exhaust valves in the LS3 are sodium filled.  I had a lifter go bad at 140,000 Km and wore out the cam and subsequently ran hardened steel through the oil pump and bearings  :headbanger: 8 PSI oil pressure on these motors is way too low, so it was time for a rebuild.  Here is my build specs, it took me 8 week of work after the day job and on weekends, with some summer holidays thrown in the mix.

Tuned by a local guy.

The truck is AWD so hard to find a dyno for it.  estimated power is right about 500 hp at the crank up from the stock 403 hp.
Sorry for my ramblings I hope someone is interested.  It has been a big time suck and now I need to get the TCS motor back together so I can start driving that car again.

Nice motor! That's really bad luck the lifter failed!

It was really bad luck.  My wife and I bought the truck last February to help cart around the kids to hockey and up to her Mom's place 4 hours away and it was down for the count this first summer but all the work will be worth it in the end for the years to come.  We don't tend to flip cars a lot so it is an investment for years of driving.  The last truck was a Yukon with 430,000 km. 

The best part of getting this done besides driving it is getting to work on the Loti again.  I can't wait.
