    Not trying to stir up anything but, all cranks are steel. None are made of iron. The only difference is one is poured into a form and the other is cut out of a billet.

    My old one is cast iron. I think everything now that is cast in sand is steel.

    I might be wrong. Maybe is just the early chevy stuff.

    How did you come up with that? Indeed many OE cranks are cast iron....cranks can also be casted in steel or be forged.

    I don't know how I came up with it. Think I read it in one of my old books and it just stuck in my brain. Maybe its just up to '65 or '63 or something. Mine is forged ('65 327) so I never looked around much for info on the matter.

    umm, no. cranks are made from cast iron, which are poured into a mold, forged cranks are made from a ingot which is essentially hammered (forged) into shape, and billet, which is cut from a solid chunk of steel

    I encourage everyone in a situation like yours to upgrade to a Hyd Roller cam. It's worth it from a durability perspective if nothing else.

    What gears and torque converter are you currently running? Want to make sure whatever cam you go with will be compatible

    I have thought about an overdrive trans but I really don't use the car on the highway. I guess once I look into the cost of a rebuild vs overdrive I will make a better decision on that but for me the overdrive isn't a huge deal.

    I am currently running a posi 10 bolt 3.73 and the convertor is a B&M Holeshot 2400 if I remember correctly.

    The idea of going to a 383 is appealing but would require really tearing the motor down much more than a cam change would. I appreciate all the incite and I am thinking a call to Howards may be in order.

    I agree with Lowend...if you have the coin for that kind of upgrade. However... that XE268 isn't working the valves on AFR 195's anywhere close to their sweet spot. Just one size up with the XE274 (which is what I run) doesn't sound like much, but it's pretty significant.

    I would stay with a dual pattern cam vs a single pattern. If you look at the profiles, the XE274 appears to fall between the Magnum 280 and Magnum 286...but dual pattern. Need at least a 2500 stall and 3.42 gear out back to run it. The rest of your engine would be compatible with it.
