It'll run, but the Vortec ECM lacks HO maps for the fuel requirements of a 502 ht
Gotta add that "doable" can be confusing. Your Vortec has modified square ports. Only 7.4 uses these ports. 502 engines are typical of 70's oval port heads. If you want a 502. Build one based on your engine.
Unless...you're ok with aftermarket FI or carb, and standalone trans control, a 502 crate motor isn't ideal. Your Vortec FI will not bolt onto the 502 unless you use Vortec heads, which can be done.
Drop in a Scat stroker, bore .060 over and you'll have a 502 Vortec. And an engine worth 4 times the value of most 'burbs. With good cam choice. It will perform very well below 4000 rpm.
