    Could you use a grease pencil to trace around the hinge where it mates with the hood?
    At least you could wipe the mark away when your re-installed.

    i just picked up another set of bits from lowes this evening, hoping to have it cleaner looking by the weekend...work and wife permitting :)
    I wish I had time to test the stock vs ported intake, i think with the cam and larger displacement the port work will be well worth it. I'll need to gasket match the eagle heads for the larger 6.1 intake ports before final assembly.


    good idea, i was thinking sharpie but the grease would be much easier to clean off. thanks.

    Sounds like you are making nice progress. Are you going to get the manifold bench flowed after your porting?

    nah, just install it and go. I don't know a local place that will do that and I don't have the funds if it's expensive.

    update: ordered a mopar damper, the aftermarket one was garbage....
    Also ordered a replacement oil squirter assembly and replacement crank bolt.
    Steve white motors is awesome, got a great deal and free shipping.

    After read a LARGE amount of information on the oil squirters, I have decided to keep mine in place.
    The 405 crank should allow the pistons to clear, if not I'll adjust fire, but the benefits of the squirters spraying oil on the back side of the pistons at high rpms is worth the effort in my opinion.

    once the damper arrives I'll have the keyway machined into it and be good to go.

    here's the part number if anyone else needs it:

    currently debating on swapping from SRT8 shorties to long tubes...not sure if they are worth the $800-$1000 as the shorties seem to flow pretty good.

    block boring & honing is completed, going to drop off the reluctor wheel and look into maybe going red with the block. the 2006 factory block paint is pretty much done, and I want to match it with the color scheme on the car already. Wire brush it, shoot it with some self-etching primer and red engine block paint.

    If I didn't mention it before: make sure the wheel you install matches what PCM you are using.
    All 09 and later 5.7/6.1 use the same wheel. Pre-09 6.1s and 5.7 used different wheel attachment points and different tooth counts.

    Next hurdle...valve spring debacle.
    So after speaking with PAC the fix for the 1235 springs working with the .625 lift on the big cam is setting the install height to 1.850, or swapping to 1211X springs and larger retainers.

    UPDATE: Displacement changed to 426 due to non-availability of 3.90 crank.
    K1 has discontinued the 3.90 crank, so they sent us a 426 (4.080) crank and rod kit...this was discovered when the machine shop was balancing the crank and got a good look at the model numbers.

    Not a big deal, 20 cubic inches more displacement and a slightly larger cam profile.

    The piston squirters, crank bolt, and other misc parts I ordered from steve white won't be in until next week so build will be on pause.

    We are looking at upgrading to LS double spring style valve springs as they are much more affordable than similar setups from companies / vendors I won't mention here.
    Once I get the heads off that will be hammered out for sure, but right now it's looking like double springs will handle the .625 lift better than the beehives I previously installed.

    more to follow...

    thanks, i was kinda miffed at first but I am ok with it now.

    I was thinking the same thing. I am going to try and find a place to make a custom fender badge with the scat pack bee and '426' under it.

    I was thinking 426 Hemi to go on your shaker. That is just so old school.

    update: ordered melling high volume pump and mopar water pump from Rockauto, I'll need to google how to swap in the high pressure spring required when running the piston squirters.
    Summit has the oil pump pickup tube for $20, the dipstick & tube are $17 from rockauto...the little parts are starting to add up.

    need some help: what size and thread type are the 6.1 intake bolts?
    I'm not paying dodge $10 each when I can get a better grade bolt from fastnal for half the price.
