Sorry about the delays in updating. Got really busy at home and work.
Basically, after messing up the LLT and my horrible runs at CFest, I decided to buy a new LLT motor, build it for more power, and try to find a better tuning solution. We had no luck on the tuning, so we thought about chancing the ECU for the Delphi unit used in the LFX. Unfortunately, that was going to be expensive. So, GPI got me a low mileage 2013 and I traded my 2010 for that. We put the new LLT engine in the old 2010, along with the rest of the drive train from the 2013. It sold the day they put it on the lot and is still running well.
We then put the transmission, driveshaft and differential from my old build in this new car and ordered some 10:1 compression ratio Diamond forged pistons. Everything else on the old LLT motor looked great. The bearings looked brand new.
We have a local shop that builds for Nascar and NHRA. He's been consulting with us and he said the design of these LLT/LFX motors is amazing. Rods and crank are much better than stock LS parts. He loves the design of the block with nice think walls and good webbing. He thinks they'll hold quite a lot of power if we don't do something stupid.
I'll get you some pics of the intake system he designed for us if I get a chance tonight. Otherwise, it will probably be this weekend.
