You're saying that I didn't install my cams correctly?aljordan said:
That video is good if you know how you're engine will react to the cams. So you can accomplish the same thing by going to a dyno with adjustable cam gears.
But yes, that's a good educational link.

I love all your sounds.

Mine are in correctly, we did all that. I may have a pic of my adj cam gears, at TDC, with BC264's.
YOU ARE KIDDING ME!! THOSE TWO IDIOTS ACTUALLY DO KNOW SOMETHING?!
Wow. I'm flabbergasted. I remember when I first saw that '2nr TV' show, and I just died in laughter.
Yes, what they just showed you was degreeing the camshaft(s). It's not some mystic voodoo - it's a damn standard way of building an engine properly.
Even if you don't have a cam card, you always want to know exactly where your cam events take place.

If I hear "super trick" one more time I'm gonna shoot myself. Other than that the link was a good one.

I didn't degree my cams because I didn't know I needed too. Now that the engine is in and running I keep getting told to degree them. It's not so easy with it in the car and I don't have the degreeing kit. I have adjusted them numerous times on the dyno so maybe their set close enough. I'd hate to know that not degreeing them is the reason my torque is so low instead of the overlap. Some 1jz's have the same torque as horsepower, but mine is 446 to 341........that's got to suck.
You guys ever see the movie 'Falling Down'? That's me, with one more 'super trick' 
Seriously, if you are building a motor, you need to measure and document every single measurement in your motor. When you are building a motor for 2x-3x the stock power output, it's even more essential!

The ideal way, would be to degree the cams upon install, and then hit the dyno for some cam tuning.
I helped install some cams on a 2g DSM and we got ZERO more mph, or ET in the 1/4 mile. No gain at all. Nothing. Likely due to us not degreeing them.
I would suspect that crower did some work on the motor to find the place where they make the best power. Cam tuning can move that power around on the curve. Either get more mid range power, or more high end power. Additionally, all motors are different. Big valves and a worked head will change when one should open/close the valves.

Another thing, don't just go and scream 'OMG STAGE 2 CAM POWER YAY' and somehow throw it at your motor and think you've got tons of power.
You need to pair a set of camshafts that compliment your engine - it's a system, not just a specific piece, that makes the magic happen

the old art of degre lost to the young crowd.
Where is Moses/IJ. when ya need him! (sleeping about now)
The 10 commandment of engine building!!!

That was with Robert Duball I think. I remember watching it about five times when it came out. That was a great movie. I wouldn't have paid a dollar for that coke either.............:biglaugh:

Duvall was the cop trying to track Douglas down in that movie ... sheesh - kids.
Now somebody post up some before & after dyno numbers!
Wayne G. said:
I stand corrected. I sat here and kept telling myself it was Michael Douglas, but for some reason Robert Duvall's image kept coming in my head. I guess they were both in it though, so I wasn't completely wrong.

LMAO Wayne :icon_razz
I ALWAYS degree my Cams to 0 by the timing tag, this way I have a baseline and then can play on the dyno to see where/how it shifts the powerband around.
I can also return to my baseline if things go bad.
There is no "Magic" and I'd be very surprised if BC had a running 7M to test this on and optimise them.
