im really curious as to what the deal is though. id like to see the graph, by looking at just the numbers im wondering if possibly one of the cams was possibly not switching at all? did you verify they were indeed working?


And that is completely 100% the truth and why I do every possible thing I can do on my car 100% myself. If something happens im the only one to blame and ive never had any major issues with my built motor or the countless that ive built for friends and customers. If I had all the right equipment I would do all my own welding, fab work, and so on. Unfortunately I dont have the money for that so I pay the best to do that kind of stuff for me. I did give it a shot though before going that route though.

It really doesnt take a genius to build a motor or hell even a stroker 2.4L motor. As long as you have a properly sleeved block that you dont have to worry about its not that hard. You should be able to tell if something doesnt look right such as on Strattons motor with the pistons sticking well up above the top of the cylinder. That should have been caught in the very beginning and never assembled. Something like that if you have a little common knowledge on assembling a motor should be caught and dealt with before destroying a motor.

stand-by folks
because of the time, effort and expense of pulling the head, i decided to get a second opinion on the borescope. so yesterday i threw the car back together and off the jack-stands.
Monday the car goes in to a local aquaintence' private shop for a thorough going over. this guy has been building race cars for over 40 years. he has the knowledge, experience and tools needed to diagnose and repair just about any internal combustion engine. besides re-scoping the cylinders he's also gonna due a leakdown and compression test. i should know the results by Monday evening (fingers crossed)

update +- :)
my man found NOTHING upsetting to him within the combustion chambers, whew!
he said compression was pretty even, though higher than he expected. leak down was good also.
he did find the msd 8969 that was controlling the exhaust cam has an intermittent failure! sometimes it works fine, then doesn't, then does. that explains the dyno chart wavering then falling after the exh switch point.
i've had the 2 8969's zip-tied back to back and sitting loosely on the battery tray for like 7 yrs. when overflowing battery acid began to melt the plastic cases i tried neutralizing it with baking soda/water solution. oh well.
so, a new switching solution is in order. i can temporarily use just 1 8969 to switch both cams but i'm looking for something, maybe smaller, that could do both separately. i like the idea of separate cam switching because of the smoother power band AND i can get a little boost on the intake bigs without additional exhaust noise (stealth mode)
cam switching recommendations welcome. whats the latest/ greatest gadget to handle the duties?

First time posting in your thread but I have been following it for a while now. Glad to see that there doesn't appear to be anything major wrong with the motor.

Did I read it right? 200+ on the small lobes....nice!

Cheap, effective and just an idea.....
