MRL solid roller lifter question.

OK. Thanks. I was just wondering what Mike dyno’d the engine with and what you used.

Ignition can have a big play in final power. The carb has a little. Still, the shown gap between the two and the two parts that were changed only leaves the dyno, the operator and the correction factors of the machine.

37 hp & 50 lbs./tq is a lot. But (could be) understandable to a degree with the changes.
