Default Anybody have a L76 dyno chart
Looking for a power curve for a L76 (stock). Interested in the torque ability in the lower rpm's (2500-3200).

at the crank by the way... Looking for a comparison between this and the 5.3 L33. Motor is for a jet boat. Need torque around 3000 rpm. From what I've researched thus far, the L33 performance at this rpm is the same as the L76????? Seems weird...

Coban I appreciate the charts. Good info.

With a cam, carb, msd ignition, what is a realistic torque increase in the L76's 3000 rpm range?
