Happy motor

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

Shooting for next week, have to hang transom assemblies and finish odds and ends in the bildge this weekend

So what is the actual Comp Cams part number?

01-446-11 pn

Winner, winner. !!!!!

Lol correct!

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.

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.

I really feel that subject matter is not a debate. Some things are just what they are.

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.

The debate I referred to was in my head, after I looked at the facts, it was over

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
