The numbers for Erson/BFE #24 mentioned by David and Henry is the
last one in my list and has the longest duration. Like Henry said,
if you drop below 4,000 your dead.<br>
<br>
I got interested in the history of cam design. According the Speedy
Bill Smith (Speedway Motors) the real innovators after WWII were Ed
Winfield and Collins of Harmon-Collins (see the book "Souping the
Stock Engine). He said their designs were heavily copied by the
others. I think Kas's cams were designed by someone from
Harmon-Collins.<br>
<br>
I certainly don't have the experience of many others on this list,
but I'll contribute a few comments on what Rick has said. Cams is a
subject that is mysterious (Rick said "black art") to many, so it is
easy for them to be fooled. There is nothing mysterious about it. I
agree that most people put to much emphasis on peak HP rather than
the entire range you will operate in.<br>

Hi FOT,
<div><br>
</div>
<div>I used Larry Young’s site to learn a lot about cams and their
relative effects on engine performance with some crude engine
modeling software, in the quest to pick the right cam for my
wants, building a strong mid range engine, trying not to spin
over 6,000 if I can help it with a stock based crank. Does
anyone happen to have the specs on the Gillander’s #24 they
could share? Just curious. Maybe it’s at the pointy end of the
list below?</div>

</div>
<div>Rick McCurdy, here’s the cam reference list Larry put
together, below, and I’d sure be curious what Rick Parent’s
software would say I should have done!!! </div>
