I was just looking over some more modern inline engines and I came across the Vortec 4200. It has some pretty serious stock HP over my 69 Chevy 250. Is there any real benefit to building the 250 over putting a Vtec 4200 in there? I'm not planning on doing this but I was just wondering. Why do people build the old engines over just putting in 2000s engines? Nostalgia? or is the price per HP better if you're building an old engine or what?
