    Question engine durability question

    so I have posted when I ripped my heads off and found what APPEAR to be cast pistons... so i assume it has stock rods and maybe a steel crank but not sure (have not pulled the motor) the block is a 4 bolt BBC that is stock bore. the heads have been redone at some point and are off a 427 and pretty much stock.

    my question is what is the durability of this motor, yes yes i know no one can give anything exact but what would one tend to think... it still has the cross hone marks in the cylinders. it will turn about 5500 at WOT, it has a tunnel ram with dual holley 450's that have been beefed up....the plugs are a nice brown. the guy i bought it from didnt know squat about the engine so what do you guys think, anything tips on how to run it so it will last this summer? I am changing the pan from a stocker to a 10qt dooley.

    thanks!

    IMO...i believe that if you keep your foot out of it & only turn it around 5000-5200 rpm, it will get you thru the summer with no problems ...the addition of the 10qt pan was a sound idea...stock cast piston motors will last if you take care of them...meaning...try & keep your foot out of it ...they won't take excessive rpm's for a long period of time! (WOT)...just sayin' my .02 cents

    I would look at replacing the valves if they are the stockers. One broken valve caused this mess....and took out the block as well. My cast pistons, rods and crank held up fine until the valve dropped....

    good advise guys... yeah keeping oil temps down with the new pan and keeping it running a little on the rich side is what I have heard helps keep things in check, also the foot out of it

    DO NOT POLLUTE THE OIL with raw fuel......If your oil gets black quickly, you're too fat............Ray
