A few months ago my LS1 engine ate the roller of a lifter. So new lifters, value train, Brian Tooley Stage 4 cam, crank bearings were damaged too, so put in a 383ci stroker kit. Every moving part was changed. (still need to update sig) The engine is still N/A.
500miles on the engine now, and been doing some tuning. done a couple of WOT runs, had to take fuel away at lower cruising RPM's, and add over 20% at WOT.
Now my VE gets up to 115%, these numbers were around 100% before the stroker.
Just thought I'd share. All going well.
Getting something oddity on start up where it runs lean, but if I leave it a couple of mins and all is fine. I still have start up enrichment. Possibly WB gauge not reading right at the start, but the car is definitely stumbling, then suddenly runs fine. So perhaps the gauge is fine. That's about the last thing i need to look into after this rebuild.
Its probably fine when it warms up because it goes to closed loop. Reset your fuel trims and watch them after start up. Also verify what poster above said about your VE percentage.
As soon as engine size was mentioned, I realized I hadn't changed it. Still have it as 0.70821l
I should change that to (old cylinder volume/346)*383 = 0.7839l

I was on OL for the tuning, everything seemed spot on when driving, turned off at a car meet, then when we went to go for a cruise started up, still in OL suddenly looked all lean, it has been off for a couple of hours.
Turning fuel trims back on today, and will give it more logging, see what I get.
I'll change the cylinder size at the weekend so not to interfere with the VE scaling just yet.
