Ok- Comp version of 525 efi cam.
Happy motor https://youtu.be/NNnPRrlXK34 Granted was with dyno headers, but still stout, hopefully reliable power. No race fuel either Shell 93 out of the pump with 32 degrees timing |

PS SB thanks for the tip on the sp vs dp debate! No problem building torque in this build �� |
235/243 .610/.627 114 LSA cam.
http://news.compperformance.com/wp-c...I-Camshaft.pdf Nice combo. Should work well in that big 45 Wellcraft. Excellent torque. Should live a long time , as the lift is reasonable. No .680 lift needed to make the power,and I'm sure the valve spring pressures are reasonable as well. |

Lol correct!
PS SB thanks for the tip on the sp vs dp debate! No problem building torque in this build �� Are those A/F ratio's from wideband ? Appears so. If they are , looks like one side of carb could stand a little more fuel. Good luck with the boat - looks like the engine part went well. |
That is a nice flat torque curve.

Yes there are 8 widebands you are looking at cyl 3&4, that run was without air filter, installing it cost 2 hp but also evened out the a/f |
