I've owned a 1995 K1500, L05 350 TBI since 1999. The existing motor is getting tired and I'm looking to purchase a new Vortec long block through Pace Performance. I plan to purchase a conversion intake manifold and retain my TBI. I'll install a better fuel pump, increase fuel pressure and adjust fuel and spark tables as needed. Before I pull the trigger on this conversion, are there any "fatal flaws" with this plan I need to be aware of? Thanks in advance.
