I would never scrap an LT1 for a GEN I small block unless I was building an All out race car and using a very expensive block (non-production block). The LT1 improved upon the standard Gen I in enough ways to make it an infamous engine within its 5 year run! There are LT1 production blocks out there running at the 1000 HP mark without issues, Very few production Gen I blocks can handle the stresses from high HP applications, hence the need for non production blocks. The LS1 is a different story...It's Head design alone reinvented the small Block platform and made the Gen I and Gen II look like a piece of ancient history!
