I am building a 351W 0.30 over bore. I have a comp cam 268 series which is pretty mild with all the up grades to the valve train on my heads. I have a set of srp forged pistons for nitros or blower application. I was planning on using my stock crank and stock rods with a twin turbo set up. I am wanting to know will the crank hold up to the preassure.

depends on how much boost you plan on running but it'll hold up to some

if u are seriosly going to put a bunch of boost to it spend the money now buy the better crank and rods and then you wont have to rebuild it once the boost destroys the stock cast crank.

Stock cranks are pretty tough, they tend to outlast the blocks provided they don't see high rpm. Cast iron has relatively low tensile strength, so the centrifugal force of higher rpm causes them to come apart under power. With a cam that small You'd be hard pressed to break a stock crank on a pump gas turbo. You'd detonate most likely before your crank failed from not being up to the task.
