Allows one to diagnose internal engine component wear with only a few cell phone snap shots.
How the hell did anyone ever build anything before the interwebs?

Its not too late to change things Tim. Let me throw this out there.
Bore the blocks to 4.560, throw in some 4.375 cranks. You'll have some 572's. Then, you may want to look at some 781 GM oval ports. Not quite a peanut port(too much torque with peanuts), but more of an Almond port. Around 250cc or so. Stick a 2.400 intake valve in there. Theres plenty of room. I would look at a cam, in the 218/224 range, with a .400 lobe. But this time, lets go with a 1.9 rocker arm, for 760 lift at the valve. Lets shoot for a throat diameter, of about 1.45, with the 2.4 intake valve. REALLY get the air moving fast. Mill the heads, idk, about .125. Get some compression in those things.
I'm pretty sure, you can make 892ft lbs of torque, at 2600rpm, and about 260hp at 6000. It won't matter that the hp is down, because TORQUE is what carries the boat. Slap on a pair of custom 40 pitch mirage plus props, and 1:1 gears in those trs. You'll have a cruise speed of 50mph, at 2000rpm, right before it detonates so hard, it shears those arp rod bolts.

Thats the I-Motor app...you really need to get with the 21st century..... You can even take a pik of a cam and Siri will give you the complete specs and even the springs needed....

They uploaded wrong basically just showing another set of cams, not bob specs, not cam motion... and same type of wear... at this point I'm buying new cams and all grinds are very close so if the grind was my issues then I will be good to go.

Its almost as high tech, as the broom thats used to sweep issues under the rug these days!
