Looking to build a turbo motor and trying to hold off getting an aftermarket block for a few years. Regardless of which block I get, the basic plan is to do a low fill of the water jackets and a girdle for support and rigidity. The only reason I'm considering the 413 is to lower the displacement a hair to better match the turbo and I heard that the 413's are underbored 440's so the cylinder walls are thicker but have not had that confirmed, so if anyone could chime in on that it'd be much appreciated. My main concern with the 413 is availability and support in the aftermarket compared to 440's on parts such as pistons. Any thoughts and advice would be appreciated,
Thanks,
Jack
