455 Engine camshaft

Yes, very similar. When I left drag racing, it wasn't exactly voluntarily.
It was an addiction with me. I was newly married at the time, and was
spending household money to support my racing habit. My wife sat me down
and simply stated the facts. "Do you want to go racing, or do you want to
be married? Your choice".
So I cleaned out every last bit of stuff related to racing, shoeboxes
full of receipts and invoices, trophies, everything. I made her a promise,
No more race cars. I still remember the sound that small block made. It
still invokes memories when I hear a well tuned engine run.
Ah yes, TransAm Camaros. Probably the same block and etc. Chev made a Z-28
OPTION in 67-68 with a similar motor, before they went to the 396 in 69.
What a giant leap backwards that was. As Johnny Carson used to say, thanks
for the trip down memory lane.

Jim, your experiences kind of sounds like the movie that Ada and I saw last night. "Ford vs Ferrari". ... and the reminder of "7,000 rpm". ;)

Before Ed developed the cam I described along with the rev kit, that was
our rpm limit, too. But, his "secret cam" allowed us a couple thousand more
rpm. We had some oil foaming issues that came along, but borrowed a dry
sump system from the roundie-round guys (outlaw cars before the wing tops)
and that cured the oiling problems. We always covered our engine stuff from
curiosity seekers, they all wondered how we could rev that small block like
that. Speed secrets are often very expensive to learn. Always somebody
wants to learn them for free.

We did that with a GM diesel cam.
Its great to find out that Crane knows how to overcome this issue.

Johnny, this thread has morphed into something else!
You got me thinking about the flipper wing Chaparral's and Scarabs of
Jim Hall and Lance Reventlow and those "godawfullfast" CanAm cars. I loved
the concept of American Muscle Motors and a run whatcha brung attitude.
Both left and right hand turns, brakes were as important as go fast stuff.
Uphills, downhills, increasing radius and decreasing radius power on and
hard braking turns, NO STINKING CHICANERY in the way. Real racing. Loved
em. Short lived series, sadly.

Ok, so the best I can tell, please correct me if I am wrong, is that the
scallop at the top of the roller lifters is only needed to be able to
install lifter pairs while the heads remain on the block. So its an
installation clearance issues not an operational issue?

It is an installation clearance issue with the intake manifold. The thing about roller lifters is that they are taller, so they stick out of the hole
more. Normally, the only thing above the hole is the pushrod, which is skinny. With the Toronado type intake, it sits down in the valley so much
that the underside of the intake will contact one or more of the lifters it they were round at the top. They are scalloped for the clearance. The
lifters don't need to be tall all the way around because the link bar only needs to be on one side. So they attach the link bar on one side, and
scallop the inside. I circled it on the picture at the link below. There are multiple companies that make them, but I definitely know that not all
retrofit roller lifters for the olds have the scallops.

Ok now it makes sense! Thanks for pointing it out on the picture.

That is one beautiful engine. Great work.
