Awesome and sad ride report

Rob thats a real kick in the guts.

I sure hope you have not done too much damage to that power machine you have built.
 
Off to bed, content, everything seems fine. Going to bolt in the new cams and get a chain on order tomorrow.

The broken chain even measures within service limits and has no visible wear aside from the **** snapped link.
Do you have the 450bhp resistant @warp9.9 chain tensioner mod in? - Now's the time if not!.
 
Christ. Dude you're either the world's most ham fisted pilot or the unluckiest.:eek:

What was the chain length over 23 links (outside of pin 0 to outside pin 23)?

Recommend a $30 1080p colour wifi borescope to inspect piston faces before pulling heads
 
And this goes away forever!

Well the stars and moon must be aligned if you didnt damage any valves etc............. could the chain have been tensioned too tight??, just seems odd to break a chain... just a thought and interested to see if you can find a cause.

IMHOP, I like Nevs manual tensioner better. Im not sure on the plunger diameter but if it is the same size as the OEM unit modifyong the shoe on you cam guide to fit Nevs is No problem. I used a modified auto tensioner on the falcon which I liked and never had to worry about adustment except to check the safety stud. But as manual tensioners go I've had my hands on both and adjusted both and I would run Nevs as a first choice. I'll have to go back and read some more but I agree with the scoping of the pistons. And seeing if the cam guide adjuster side is cracked.
