Visible V8 modified camshaft Nov 24 2010

A new modified camshaft is put to the test in this video. The new camshaft has some overlap put into it. The engine is much louder now. It makes my ears ring, so I have been using ear protection at high speeds.

The shear pin, a cut 2-56 Nylon screw, in the drive shaft failed when a intake valve spring broke in two, allowing the push rod to drop out down into the crankshaft, jamming the crankshaft. The shear pin worked perfect and protected the crankshaft from damage. The pushrod was laying in the bottom of the pan, bent, but the crankshaft looked ok and was put back to work after a valve spring repair. Runs fine now.
I was really pushing it all morning near 6000 RPM at times before making this video. The stock valve springs will shatter above 6000 RPM, so 6000 RPM is the current red line.
This set up has a Dayton 1/2 HP AC DC 120 volt electric motor that has the power to push this engine to destruction, but I try to keep it under the red line (most of the time)

@benrobinson72 Thanks, It is really loud too. I have been using ear protection while running at high speeds.

@benrobinson72 It did on block #1, but it really did not do much and was hard to plumb up, so I just left it disconnected on this block, block #2, #3. There are several filters in the oil lines from the external oil pump. I found out that clean oil is important. The first crankshaft used in block #2 had a chunk of something in the oil line that fed the front main bearing. The bearing was trashed out on start up. I was able to repair it and it ran a long time in block # 2.

btw dose that oil filter actually work
