496ci Stroker with Longram intakes

My 496″ stroker engine (re)build pics:

“Hawks Racing” 4.15″ stroker crank, H-Beam rods, 10.5:1cr Diamond-pistons.

Had to clearance the engine-block at some places so the rods didn’t hit it…

After contemplating in which car I wanted to put this engine, I ended up deciding for my 1960 Chrysler NY.
I have also installed a set of LongRam-intakes on the engine in the car, so I had to alter a couple of things on the engine before this would fit. Therefore I’ve changed the cam for a more milder hydraulic grind which works better with the longram intakes.

  1. Cool setup! So what cam are you using? I am building a similar setup and having trouble deciding on a cam…

  2. Hi Dave,

    I used a little above stock cam in this motor. Don’t know the specs exactly as I bought it used with all the lifters in place.
    If I had to guess I think the cam is in the 268 to 272 adv. duration region. Pretty tame.
    I did use 1.6:1 ratio rockers to increase the cam’s lift a bit.

    In the mean time I have bought a roller cam to be used in the motor, but haven’t gotten around installing it yet.
    The roller has the following specs:
    CompCam XR274R-10 – Mechanical Roller
    Advertised Duration 274/280, Lift .564/.570

    I’m not yet sure how well this cam will work with the longrams, but with 500 cubic inches on tap for streetuse only I don’t think I won’t loose much power anyway.

  3. Good to see longrams in place. Have two pair with the carb heaters butchered-off my p.o.
    Set of short rams too.

  4. Hello Lee,
    Propane is widely used over here aswell. It’s about 1/3 to 1/2 cheaper then regular gas here.
    Short rams are cool. I’ve got 2 pairs of longrams.
    At the moment the longrams are off the ’60 NY’er for the time being, and a dual carb inline intake has been installed instead. Since I’ve just installed a mechanical roller cam, I’ll be adjusting the valves a couple of times probably. Without the longrams in the way this will make the job a lot easier and faster.

  5. Hi, I dig your oldcar stroker setup!
    I linked into your site from Moparts where you had a clever comment on making a ball joint tool. Great to see that there are Mopar enthusiasts in many European countries!

    Kind regards

  6. Former owner of the ’60 New Yorker checking in on it… glad to see that it got a fine engine to replace the failed 413. Long rams were my dream for the car, and I’m pleased to see that it happened, even if it took better hands than mine to make it work!

    Cheers,
