i keep seeing posts of how the old iron dude engines are..maybe someone can tell what type of noise these engines really make.hell.mine just had the crank turned and new lower bearings.sounds like the thing is going to blow apart.but the oil presure is around 40 or so at 3000 rpm's and around 25 to 30 at idle. with running wd 40 oil.any comments on this ,please.<br />it's a 88 motor with a 86 omc cobra.Thank you so much.
