Yeah, tough call for sure 'cause the advantages with the LS extend to handling due to smaller package, sits lower and more centered in the car. But what that would be worth per lap is hard to guess at, I've never seen an apples to apples comparison of the two engines in an identical S550. Then there's the design factor, the 'yote is a modern sophisticated design with DOHC 4 valve layout while the the LS is just an old school 2 valve OHV and the 'yote makes more HP per cube. That's what attracted me to the car initially.It’s a hard decision and there’s lots of factors but I’m thinking coyote now as the overall cost is lower and the valvetrain is more stable at high rpms. The more I read about LS’s the more it seems the valvetrains either need to stay close to stock or you need to do a ton if you want to run a big cam. Since I don’t have the funds to do the swap and a full valvetrain I’d be at the same power levels as a coyote. So then the coyote is the easy button. Much worse transmission though... I dunno we’ll see.
Well you have a couple more years if it's a 2016 as new vehicles are good for the first 8yrs. Sent you a PM as well.Good question, still undecided on that. I’d like to keep plates on it so since I’m keeping all the stock emissions from the coyote for now I’m thinking to take it to the referee for certification. We’ll see.
Super jealous of that garage. Congrats on the new house!Wiring harnesses and drivetrain in. Got a healthy number of DTC’s though that I need to sort through before first startup. We’ll see what I can do with Forscan, hopefully don’t need IDS.

What appears to be the biggest issue is the canbus network not finding the EPAS rack. Testing circuits to make sure it’s getting power, maybe I’ll get lucky and the fusible link is blown.
The great news though is that after doing this engine swap in my driveway in the leaves after dark once my boys are in bed, we are closing today on a new house with a pretty butchin’ garage. So getting my car running and future work will be much more enjoyable! Slab engineered to support a 2 post lift, really looking forward to that. Super pumped.
