    Lingenfelter 427 N/A package details

    Here are some details on our Cadillac CTSV 427 N/A package. This is the same combination that we used in the Car and Driver shootout. If you saw it on TV, then you are aware of the smoothness, and reliability of this combination.

    The package includes:

    Engine removal, inspection, and dissassembly
    Block machining and machining for sleeves
    Custom aluminum block preperation
    Darton modular sleeve assemblies

    Stainless steel 2.100" hollow stem intake valves
    Stainless steel 1.57" hollow stem sodium filled exhaust valves
    Comp Cams double valve springs and titanium retainers

    Custom designed Lingenfelter hydraulic roller camshaft
    1.85:1 roller rocker arms and HD push rods

    Lingenfelter HD rocker arm stands

    Package price: $24,995.00

    Honestly, when you stand next to one of these at idle, you would swear it was a stock car with an exhaust system on it!

    Let me know if I can answer any questions,

    Is the 427 going to be a new block, or bore out the current LS6? Also do you guys offer a more radical cam for any of your 427 packages?

    Hi Nick -

    We do bore and re-sleeve the existing LS6 block, utilizing the Darton modular sleeves. We can build the same engine utilizing a C5R engine block if you prefer, but at these power levels, it really isn't worth the extra cost.

    We do have another more radical cam available, which will make a lot better power, but it is going to have a more "lopey" idle, and probably won't pass an emissions test. We have used this cam in 427 N/A Corvettes and seen about 495RWHP

    Let me know what you think,

    Down here in Florida there are no more emissions tests, and I would prefer the "lopey" feel and sound in a 427, so those are good things.

    Thanks for getting back to me,

    Not to hijack this thread, but what type of rear wheel numbers is a person looking at with the $7,000 head and cam package??

    No problem Shane

    It would depend on which camshaft we use, and how smooth you want it to idle. I think a safe bet would be anywhere between 380-420RWHP.
    I also have our engineering dept. working on this and should have a more definate answer by the first of the week.
