    It's all 69 specs except the cam is a MP hyd. that is real small...278 advertised. 10:1...it didn't make 500 but it was on it's way.
    I'll post some graphs tomorrow.

    Hemis are so impressive. They don't even have to run to be badass.

    the Hemi in my silver Duster is close to stock....10.5 pistons, small bump over 71 Hemi grind Comp cam (over 20 yrs old)....light in weight, but a stocker.

    saw 510 HP @5700....the cam holds em back, but for a coffee getter, it's OK

    How do you like the Jegs windage tray, gasket combo. I just changed mine out because I put silicon on the rear main and timing cover seams....leaked like the Exon Veldez. It appears that was a dumb move because apparently the silicon filled up the oil stopage valley / groove????

    I put one on a 383 build ...no leaky.

    how did yours hold up for leakage??

    these engines on turbo setups are downright scary. seen one on youtube well over a thousand horse kept blowing passenger side air inlet tube off. about 600 or so hp at 5500 and climbing like crazy it would get so far blow off tube not sure of all number details but unreal and street legal too!

    My Engine builder had one on the dyno here with a Mopar performance cam in it with stock manifolds. It made 550 hp and 575 tq. A set of headers would of given it another 50 hp or so. those motors needed to breath.
