DAMN!! You're asking for a lot of info here...Lets see what I can do with it.
>OK....
>
>Got the basic Cam specs (thanks Brian) but I need a lot more information:
>
>(1) Cam Specs: (Timing specs - Intake/Exhaust Open/Close @Valve and @.050")
Geezus!!! Um, I have no freakin idea!
>(2) Cam Specs: Lift @ Tappet
Just for kicks, tappet lift....sh!t....okay.....try .2375" intake(.380" at
the valve)
exhaust .245" (.392" at the valve)
>(3) Cam Specs: Duration @.050"
Wheee! Well, for the hell of it, 180 intake/184 exhaust....
>(4) Cam Specs: (Don't think it's advanced or retarded from the factory)
>Degrees Installed??
It's installed straight up. Should be 0 degrees.
>(5) Valve Spring Rates (Seated and Open)
Where the hell is a Magnum techie when you need him?????????
>(6) Stock Rocker Arm Ratio (1.6:1 I think)
Yup, 1.6:1
>(7) Number of Piston Rings
3 - 2 compression rings, 1 oil ring
>(8) Connecting Rod Length
6.123"
>(9) Piston Skirt Length
Something leads me to believe that this is the same thing as deck height,
no? Well, the "A" engine block has a deck height of 9.56" - which should
be the same as the Magnums.
>(10) Valve Sizes (Intake and Exhaust)
Intake - 1.92" (might be smaller on a V6 - if it is, probably 1.88"
Exhaust - 1.625" same across the board....
>(11) Combustion Chamber Size (cc's)
65 cc + 11.2 cc dish on pistons
>(12) TBI CFM Rating (Stock and Stage-II)
umm...lets see...550 maybe? Stage II...680 maybe?
>(13) Average Intake Runner Length/Width
Damn Bernd!! =) My guess 17-20" length...width? 1.5"??
>(14) Injector Flow Rating (Stock)
24 lbs/hr probably....

>I'm building a hypothetical Magnum V6 (I can also do a V8 if I have the
>specs) and then modifying it to see what happens. (Intake Flow, Cam Specs,
>Exhaust Flow, Timing, Rocker Arms, etc...)

>I'll have printouts posted but I need these specs before I can do anything.

GOOD FREAKIN LORD!!! =) Ackk....that was interesting...I actually think I
got 7 of those perfectly correct. On the #'s: 1, 2, 3, 5, 12, 13, 14 - I'm
not too sure. Pure speculation on some of it, and most likely some good
guesses on some of it(2, 3, 12, 13, 14). I don't really think the cam
estimates can be off by that much.
Okay DML'ers, feel free to correct my mistakes! That's about as good as I
can do without tearing down the motor! =) Hoped that helped somewhat, Bernd.
Do I get my Degree in Magnum Engines now????? Or maybe a diploma of some
sort???
Brian
I think my mind is fried, thanks Bernd! hehe....=)
