"This cam requires an SCT Tuner and beehive valve springs. Iron heads require the seat pocket to be cut to accept the beehive springs"
Also thinking that a M Saine Valve body and a Locker in the ass w/ 4.56's is a must.

Might want to look at Indy's selection as well from. From what I hear I think they make a head that allows magnum accessories to be used.
You can use just about any Small Block head.
Just a matter if you want to keep the Magnum Acc. or not? Even that can be done as well.

Hot rodder rule of thumb....every $1 invested in head flow is roughly worth $3 in the short block
If that Ryan guy at Shady Dell has a cnc program for the Eddy's, you're better off buying through him. Should be able to save a little bit of money doing it that way as opposed to buying elsewhere then sending them to him.
Already talkin to them, information wise. Also trading a few emails with Southeast Performance. This is looking like a great idea for the truck.... just not for the wallet. I can see a badass R/T if this happens, and lots of nights sleepin on the ship because the wife will kill me if I go home lol

I haven't started talkin to HemiFever yet... want to first decide if it's even worth it to try to build this monster, or do something like a 408?

Thats the message I'm getting. The only thing I was worried about, really, was the side skirts for the pinch weld. $950 shipped? Then something about the guy who made the headers, just doesn't make them anymore.... So It's back to spintechs, sweet. At this point, I'm taking notes and shopping around.
Side note, If I do get engine in truck, what other needs do you think there would be IE rear end/suspention, Tires ( 325/45/17's from M&H), and cooling for sure. Please, keep tossing ideas out here on this guys, I need all the help I can get
So, I'm more then likely going to try to build this beast after deployment in my one year in San Dawg. As a thought, is this even thinkable in a stock block?

4.030 bore, fordged pistons, 1/16",1/16",3/16" rings

6.123" fordged H beam rod @ 628 GRAMS, 2.810" main journals, 1.988 rod journals
Fordged crank
1852 GRAMS bob weight
Rod-stroke ratio is 1.464/1
" rod to block clearence is 0.30"
The last one is what scares me.... someone explane

Spintech 1 7/8" long tubes will be better for a 426 anyway. Stock block should be fine since you won't be spraying or boosting it. A set of caltracs and adjustable shocks will help with traction, along with sticky tires. The rod to block clearance is how much clearance you have between the rod end and the block as the rod is rotating, I don't know what the acceptable limits are, but .30" is a good amount of space.
I've also been considering this 426 kit as well. I'd be purchasing the kit from Hughes and having the work done else where. From what I gather, a shorter rod and a larger piston would increase the durability of this kit greatly?

The rod length for the 426 kit is the same as the 360 and the 408 (6.123").
They use a crank with a longer stroke (4.180" as opposed to a 4.000" for a 408, or a 3.58" for a 360), so if you reduced the length of the rod, you would decrease the displacement. You couldn't make up the rod length reduction with a larger bore (4.030", which is the same as a 408).

sorry to get off the subject , but im wanting to build a 408 . what is the best place to deal with to get parts like the heads , the strocker kit, allready have intake , throttle body, ejectors and ill be running 11 lbs of boost on it to

I'm not quite understanding this. Maybe I'm missing something. If you used a shorter rod with the same piston wouldn't you slightly gain cubes? Now if I shorten the rod and proportionally increase the piston size the CI should stay the same but with added strength.
Also, would a shorter rod effect durability at all?

Stroke of crank remains the same, bore remains the same. Nowhere in the CID formula does it ask for rod length or compression height. You would only be changing the position of the piston in the cylinder at tdc and bdc. You are overcomplicating it guys.
bore x bore x stroke x .7854 = Displacement in cubic inches
