Motor Mount opinion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm in the process of building a 355 for my two wheel drive blazer that will be 350+ HP. It will mainly get driven on the street, and I'll beat on it, but I may also run it at the track from time to time.
I've heard that the stock motor mounts aren't that strong. Is this true? Is it worth switching to '73 and up clamshell mounts or aftermarket ones like performanceonline.com sells?
I would like to put this motor in right the first time but don't want to spend unnecessary money. Any opinions?
