my 305 TBI when new was only rated at 170hp and now that she has 141000 on her i dont think i am anywhere near that mark, would it be cheaper to buy a whole new motor, or maybe build up my existing one??

91 RS 305 TBI

Z28 grille and fogs
freshly repainted mystic teal (the orig color)

 

New 350 crate motor is singing your tune...spend the hard earned cash on rebuilding a 305, nope.
Check out the new crate motors with a warranty....

good luck!
