That's not my post.  I never saw that.  Without hooking it up to the scanner and driving it, I wouldn't know

Steve, I have been thinking about the cam profile and an issue another guy is having with high lift cam in a big block. It was and is an oversight on my part that we may have gotten the lift too great for that strong bottom end you were really looking for, basing this on the ramp speed of the roller cams. In short, it appears that the speed of the ramp with the lift, even though it is a short duration cam, part of the high vacuum signal is being lost from too much lift. I am afraid I have turned around and given you some bad information not from my lack of knowledge, but from my lack of proper application. You wouldn't by chance have a set of 1.5 rockers instead of the 1.6 rockers you have on her now? I think it would be an increase of 2inches of vacuum, which equates to more torque. Talk to me about it a bit.

I'm using the stock rockers.  I forget if they are 1.5 or 1.6.  I'll find out though
 
When I ordered the cam, I specifically went over the specs with Hughes.  That's one of the reasons they gave me a 3* advanced cam.
 
If anyone knows Magnums, it's them.

Well, yeah, there's that, but they also just kind of went with a similar cam profile and increased the lift and bleed off a little bit of the cylinder pressure like a stock cam, ro radicalness to its potential really bred into the grind itself. Dropping the lift from .509 with the 1.6 rockers to .477 with 1.5 will increase vacuum, which even with the short duration may be a very viable low end torque increaser over what it is now.  I forget how fast the ramps are in comparison to the flat tappet cams it isn't even funny.

OK, at least that isn't an issue. Did you finally get the injectors and pressure figured out?

Sure I did.  74 Intrepid 3.3 fuel regulator and the correct injectors.  I'm still putzing with the static timing

Nah  Trying to find a 12,000 package FedEx lost.  This is why I don't have a FedEx account.  Every thing I ever have shipped buy them turns into a nightmare.
 
I bumped the timing today about 4 degrees.  (Eyeballed the disty)  I can't tell yet because I have the rear bumper off, but it sure starts allot sharper.
