I liked the 118 LSA. IT ran so much better than the 115 LSA. All the durations were the same. I fealt I could loose some intake but did not want to sacrifice the exhaust duration. Cam motion then ground me a 120 LSA but the Billet core had reached it limits and they suggested cutting the exhaust duration sense they fealt it was overkill. Well that cam hurt the performance.

This was a large displacement designed to kill small block.

My NA engine runs a large LSA and I feel that it hurts the performance. But, on the dyno we found engine performance is not the problem.
