Re: Ford Cleveland NASCAR cylinder heads
They moved alot of air about 25-30 more cfm than a Yates. The the removable pushrod insert is about an 1.25" long and shaped like an airfoil. They were an improved tunnel port design but they suffered from the same thing all tunnel ports do, momentum problems. The average runner speed is too sl...

Re: Anyone been able to reach Isky Cams lately?
Ron I believe. I reached them, turns out calling on lunch break wasn't the best call. They are closed from 12:30-1:30

Been trying to pick up some parts. I know Ron passed, but I hope we can still get parts.

Re: camshaft intake valve closing
I will have to see what I have in my software. This shows what you are talking about but doesn't produce identical result to yours. The RPM is a little lower for the SBF. Stan ab-tmc-bbc-sbf.gif I'm shooting a little off the hip from engines I have experience with. My EMC 289 had a 242@.050 install...

Re: camshaft intake valve closing
This maybe be off topic but I think it relates. The intake valve closing very much relates to the amount of intake valve area an engine has. This is vague but works out pretty close. If you had a lobe that was 280@ .020 250 @.050" .380" lobe lift. Took a 480" BBC with a 2.250 valve i...

Re: F/T cam with tool steel lifter
I'm sure I'm gonna get slammed for this but I think you might have some minor valve float issues. We have run tool steel alot over the last few years. The only things I saw do that were not enough spring pressure or water in the oil. 370lbs over the nose needs a hollow stem valve to get to 7200-7400...

Re: Motorcycle and ATV dyno
Do you have any details about it. What brand is it, what is the drum weight, does it have a computer when was it used last, where is it. THanks.

Re: Why 4 degrees?
Point me to a lobe design that specifically changes IVO and EVC to add overlap area while maintaining the same EVO and IVC points, outside of dynamic reasons? If anything, as everything gets more efficient, you see less time (duration) needed, and with increasing rpm's wider centerline spread, for ...

Re: Why 4 degrees?
If 600c is constant temperature of the exhaust valve why does the engine need a spark plug. In order for something to light it has to have enough energy to burn it. It could burn the fuel for a period of time but as the air fuel charge bypass the valve its heat energy will diminish rapidly. With co...
