Inliners International Forums General Discussion Engines 4200 Vortec, but is it worth it?

But if you add the cost of reflashing the ECM, oil pan , mounts etc., the cost starts to climb quick. We pulled one from an Envoy along with every wire connection and line and layed it out on the shop floor. We were overwhelmed with the complexity and wound up trading it all off. I can see it as a viable swap in the future as parts availability grows and prices come down. IMHO
