No. It's probably the same thing.
hell no i have a 305 with 7 miles on it it will out run any 350 in my town but the 305 is snappierif u want bettr throttle response go with the 305 but if u want more horsepower/torgue the 350 is ur best bet
A 5.7L is a 350 engine. A 5.0L is a 305 engine. Hope I helped. Have a good day.
well other then being able to get a 89 in a 305 and a 350, power, torque. you can do a little bit to 2.8s but not compared to what you can do to a 350
faulty thermostat, stuck fan relay, bad fan motor, no voltage to motor, bad circuit board, bad run capacitor...
Perhaps a bad thermostat and/or a heater core
No it will not. Unless the oil pressure is low on the 350 engine. If you had good oil pressure in the 305, and the 350 don't then there is something wrong with the 350. Bad oil pump, engine bearings worn out, Oil pump pick-up screen stoped up. Things like that cause low oil pressure.
You will have antifreeze leaking out and dripping on the ground.
Two easy ways to tell are if the motor takes too long to warm up. This means the thermostat may be stuck open. If the motor gets hot and the top hose on the radiator is not warm the thermostat may be stuck closed.
Check thermostat first(possibly not opening) or bad bearing water pump if turning.
Could be a bad coolant temperature sensor, fan relay or thermostat. keep in mind the fan motor itself may be bad.
putting 305 heads on a 350 will work.you have to chamfer the edges on the combustion chambers because the 305 has a smaller bore.If you leave the sharp edges you will have bad engine knocking,probably causing damage.You will probably increase compression ratio by about a point or so doing this swap also.The 305 has smaller valves and passages which is good for torque,but engine will probably not make good power above 5000 rpm.This engine would probably do well in a pickup truck,or daily driver worried more about good gas mileage instead of performance.350 heads will not work on 305 though,305 bore too small for big valves.
Bad radiator fan motor; bad radiator fan relay; clogged radiator; thermostat stuck closed; loose belt; bad water pump; hoses leaking;
