Alrighty bud.. just very frustrating in my head on what to do now exactly. Should I sell this motor and go and get a marine engine?.. or should I just change the cam out? Afraid of what else I might be missing

How much $ does it range with changing out that cam you guys thinking?

Might be missing part of the question
The cost to change out the cam listed at $245 for the cam at summitt
Would need timing chain, intake and maybe valve cover gaskets to do that

Yeah as in parts and labor range approximately off top of your head? Just to give me an idea.

Is the motor fully installed in the boat with exhaust, or does it look like this

Yes buddy, still sitting like that

Then you can do it real easy.
Remove the balancer, timing chain cover, intake and valve covers.
Remove rockers, push rods, lifters and cam
Remove cam
Rotate crank so ID mark is straight up
Install cam, cam gear and chain so the cam gear ID mark faces crank mark
Install lifters, push rods
Rotate crank and one by one adjust rockers on push rods

Put the rest back together

Edit: do use lube on all bearing journals, and soak lifters prior to install

Would the old engine cam work you think? Kind of wonder what was done to that engine because it sounded great. I’m trying to attach the video of it, but not letting me for some reason.

Video post

Is there a way I could send you this video bud? That way you can hear it?... because it definitely has a different cam in the v8 that I pulled out, sounded great. It didn’t have exhaust, but it is a video with it out of the water.
