Stop in for a cup of coffee

Been looking up cams for OMR's engine and making a spreadsheet with the specs as some of the cams don't have all of the specs to enter into desktop dyno...

I found 4 cams with conflicting specs listed... The valve timing specs don't match the listed intake lobe centerline and lobe separation angle.... :BangHead: :icon_fU:

Trying to figure out what the correct specs are...

The advertised intake centerline is 102° and lobe separation is 107°, but their valve open and close calculate to 103.5° intake centerline and 105° lobe separation angle on three of the cams... :mad:

The other cam is off 1° on the intake and exhaust duration from advertised to the valve open and close information... :mad:
Karl,
Maybe you missed this in the 340 cam thread with Wyrmrider.
Its worth reading through a few times.
There is a lack of standardization in providing cam specs.
Chrysler Corp specs are all based on the ramp change as shown on the engineering drawings.
We were able to estimate the approximate equivalent. And that brought the estimated shape closer to reported dyno tests.
This was about as close as we could get because
a) even with the later Dynomation (but not the most current version) its not capable of handling assymetric lobes.
b) Dynomation can (or could) only work from .006 measurements.
 
I went by the Habitat ReStore yesterday. They had a bunch of lumber... kinda odd dimension 3" x 3" x 8' pine. Buck a board. Sheets of OSB $10
Times I wish I had a truck...
I need to go get a new storm door. 36x80. Definitely not fitting in the Mazda. Looks like I can almost fit it flat in the Wifemobile (Journey). Just have to tie the liftgate down. Or, with the right side seats down maybe lean on an angle... :steering:
 
Keith google McAllisters in Carlisle. I have gotten serious deals there on building items, doors, windows, fixture, oak flooring.
 
Re: Cam Specs
In this post I enter the shop manual specs into Dynomation's Cam manager
340 cam specs?

Then in this post are screenshots using .004 lift to see what what effect it has.
340 cam specs?

Here's the results incorrectly using mopar's specs as if they were .006 lift specs.
340 cam specs?

Substituting the .004 specs from a replacement cam company, Dynomation finally produces a power curve that looks like the ones from the dyno tests.
340 cam specs?

if the first three posts leave you cold, start with the last post above. The others are explanatory background.

Never underestimate :rolleyes:

Got heater ducts sorted out in the Fargo. Also sealed around windshield. Hope it works. And removed visor, to adjust gutters,and replace drill taps with nuts/bolts to hold it on.
 
Got a lot of rain here. Water came in thru the door. Down the window. Plastic is in place. But I had to cut to put door speakers. Guess where it leaks? Yep. Have to figure out how to remedy this...
 
The Journey does have a roof rack- could have done that. Was not considering that because I thought it was going to rain more. With the box near 40" wide, leaning would not have been a viable option. But worked out great flat and less chance of damage. Now time to go inspect it and be sure it's not damaged inside the box...
 
Howdy all. Glad you got your coffee Keith. @zkx14
Did my usual bean crunching taste test. Both have so much more flavor than my daily grind! But, for some reason, not catching as much difference between the 2 this time. Maybe the darkness of the roast is a little different, maybe my taste took a slight hit from covid? I can smell everything now, but still don't think that is 100%. I blend them anyway and just brewed a cup. Mmmm :thumbsup::thumbsup::thumbsup:
