Cam specs in your engine ?
Jon,
I believe the specs are 262/272 110 .740/690. But remember when looking at engine power numbers that the 1st engine was 12.5: CR and that engine was 13.0:1 CR while Eric's engine is 11.2:1 CR

1 or 2 points of comp is not 70 ft lbs difference. Not even half that. You can't spin or polish that turd .
So just how much is the right cam worth? You don't need to answer. We will all find out with real dyno results in a couple of weeks.

So
 
We have tested several 700 hp engs over the years .And it's common to see about 1.5 to 2 percent increase in trq per point of comp using same components. It should break 600 ft lbs with that comp if right. Here is an example. We see 410s with 15.25 comp break 660 ft lbs all the time. Drop 2 percent per point on that. It will still be better than that 427 makes.
 
The power numbers on my posts are really irrelevant, It was posted to show what power curve for that cam is, where it starts stops and peaks for the combo. And if you want to compare numbers, he tested on a superflow, that's 5% for friction you don't get with Stuska. That should make up for any difference in compression.
 
I'm sure Eric's engine will run much better with a proper camshaft.
That's an 8,000 rpm cam. 284-298 @. 050 .... Not the correct cam for this engine at all.
I think it's going to get stomped on by some small cams.

With one of the cams in the competition 1.35 lbs ft per cube is a reasonable target = 576 lbs ft.
There should be a few that pull that off or better.
They said they were using Powell cam for base. They don't even know what cam is in it ?
 
Thanx bbf 612 and 600" for clarification. We won't degree the cam and we ain't even sure what cam we left in it, but we will give you the results. Oh the life of YouTube engine building. Lmfao!

He knows exactly what cam is in it. Are you just too lazy to watch the video ?
It's not the cam Eric was expecting to run when he got to the dyno. Sometimes shit just doesn't go as planned. That's what happened here.

Too be honest, I saw the one were Eric said he was putting Powell cam in to baseline. I don't watch everything he flaps his gums about nor do I read every sentence written on here. I'm not a you tube engine builder and I have to get the right parts in the engines I work on. I don't have every waking min to bounce the inet and keep up with it.

One of the cams, of the 16 in the competition, was run in the engine. There are 16 cams to pick, and 12-15 of them will be the Right One. The one with the most intake duration, by 10*, was not and is not the right one.

If you're going to spend your time being this critical, you might want to at least try to find out a little bit about what you're being critical about.
