    Peak horsepower was at 4458 rpm 6.6 seconds in to the run. So that give you a time vs rpm reference. Dividing up the hash marks put peak torque just under 2000 rpm.

    Oh ok thanks, i see it now, except i think the peak torque took place at about 2600 rpm, since if you look at how many seconds into the run the peak torque took place, it was at about 2.5 seconds in, and if you look at the rpm line (the middle line that climbs almost perfectly diagonal) at 2.5 seconds in its at about 2600 rpm


    too bad we dont really know what cam is in there, i would certainly be curious to find out!  Any idea on what CFM rating the carb is? Any pictures or video from the dyno tuning?

    Hi guys.

    It could be super to find what cam it has. Its has a new holley 650 cfm on the top.
    No sorry i have no film at the dynotest, it could be nice to have now.

    Nice torque numbers! Here is my 318 from forever ago (at the wheel), 13.6 was the best I ever ran on it

    wait a minute...

    DanishMopar, where you are at, do they measure Torque with "Newton Meters" or with "Foot Pounds"? I have a sneaky suspicion they use newton-meters, in which case your 332 Tq would be equal to 244 ftlbs of Tq.

    either way nice numbers and thanks for sharing!



    GoodysGotaCuda, thats a really nice hp and tq curve, looks like no matter what rpm that motor was almost always in the 'sweet spot'
