Charles, I talked to an Eagle rep and was told that their cast steel nodular cranks will hold up to 700hp +. My neighbor accross the street has a 68 firebird with a stroker pontiac motor making about the same horespower and is using an Eagle cast steel nodular crank. He turns it to 7200 rpm and runs low 5.90's, leaves on the brake at 4500 rpm. He's been running this crank now for about two years. He just freshened his motor and had the crank checked, no problems. If I stay off the nitrous routinely, I beleive it will be alright. I wanted a Genesis block with a billet steel crank and aluminum Blue Thunder heads but couln't afford it this time around. Next time I'll do it with all the parts on my wish list. For now, this engine will do just fine.
