408 vs 600 stroker

Id go 408 on 2 turbos and EFI. Fun, cheaper than a SC and better mileage. Also less shock on the driveline than a SC BB. Weight will be a tad less but more room in the bay for the turbos. turbo could use iron heads too, just port them out, flow is not paramount in a blown app. Money saved on heads could be used elsewhere. Start with a plan and stick to it, golden rule.
