I have a 98 CHEVY truck 1500 2wd it has a 305 vortex engine. My problem is I'm in construction and I need to haul loads occasionally and I also use truck to put my boat in the water. It seems to be really hard on engine and I would like more power.I don't have a lot of money to go buy create 350 and have computer reprogrammed but I do have access to a old school 350 block (Was thinking of using 305 vortex top end on) or a 2001 CHEVY donor truck with 4.8 engine (trucks been t boned but is complete)I know 4.8 is a smaller motor but from what I've read on specs it way out performs 5.0 what should I do? Thanks
