Cobra Engine Build Part 1
This will be the first in a series on the engine build for my Cobra. This is a 351W bored 0.030" with a 408 stroker crank. The intake was converted to fuel injection and featured in a previous video. I will list components as much as I can.
COMP Cams® Quick Tech: Achieving Proper Rocker Arm Geometry
http://www.compcams.com/ COMP Cams® R&D Engineer, Bradley Brown, walks us through the steps in how to calculate the right pushrod length for proper rocker arm geometry that will lead to optimum performance, better durability and maximum valve lift.
LS2 vs LS7 Lifter Length
Measuring the difference in length between the stock LS2 lifters that came out of my car, and the LS7 lifters that were removed after failure.
While I would say there's a variance of about 0.005" in my measurements, I think this proves that there is indeed a difference of about 0.050".

2 Minute Valve Spring Removal How To.
I'm in the process of rebuilding a Perkins 4 cylinder 236 cubic inch engne (4-236). I had a 4-248 engine originally but it had a hole in the block so I bought a 4-236. This is the head from the 4-248. The heads are the same so I'm rebuilding both. This is just a quick how to remove the valve springs with a hammer and deep socket. The head will require some cleaning of rusty passages since the Exhaust pipe wasn't blocked from rain and snow. Its a simple procedure and can be done inhouse. Most times you would put a rag in the cumbustion chamber to keep the valves from going down with smack of the hammer but these valves are rust stuck so I didn't use a rag this time. When you put the valves back in you would definitely use the rag method for the valves. Most older engines can be done this way. Chev, Dodge or my favorite Ford can be done this way. I'm not sure about the newer engines but it might be worth a try. This is just my experience with valve spring removal and you can expect similar results with similar head setups. You could also do this method with the head still on the engine as long as you pressurize the cylinder. That would be another howto video that is probably already posted on Youtube. I'll be posting a video of inhouse valve spring installation when I'm ready to put this head back together.
