Glad you’re getting her buttoned up!

Nah man it wasn’t taken that way at all! No worries I appreciate your kindness in clearing that up also but I totally understand and respect your concern and it made me want to find out also with the “ corrected power”! Lol I’m gonna try to give my builder a call Friday and see what shakes of it!

that’s funny I watched his videos before giving the “ go ahead “ on my heads! It made me feel better about them they are a good bang for the buck it seems. Cost a little more for the inconel valves , heavy duty springs and the 5/6 angle valve job upgrade but all in all so far I’m happy. Guess I won’t really know untill they are in the boat and the boat gets to see the water finally! Lol!

She is alive and running!! If someone wants to post this video I’ll send it. Haven’t timed it yet and still a little on the high idle side but just wanted to hear it pop off once! Pretty happy today!

That’s awesome you got the motors in. Glad to see you will be ready for water.

Were you able to come up with those correction factors on the dyno? I’m in planning process of my engine rebuilds and would be curious to know more.
