The starters are compatible with both engines, just the 350 starter will probably put out more torque than the 305.
Subtract 305 from 350 and that will give you the difference (or interval) between the two numbers:- the answer is 45. However, if you mean what is the difference between a Chevy 305 and a Chevy 350, then it is the difference between the engine bore (the cylinder) sizes. The 305 bore is 3.740 inches. And the 350 bore is 4.000 inches, giving the Chevy 350 20HP more then the Chevy 305.
yes, a 305 and 350 utilize the same block
The harminoc balancer. The 305 balancer is thin and the 350 is thicker and heaver.
no
20HP/ Horsepower. The 350 has 20 Hp more.
Depends on how the motor is set up.
Primarily the bore size. The 305 has a bore of 3.74 and the 350 is a 4.0 bore. They share the same stroke on the crank. And no, you can't bore a 305 to a 4.0 bore.
A small flywheel needs to stay with the starter that goes to it. You can use either flywheel, and the block should be drilled for either starter.
Try a search for vortec engines
Are you asking if the 350 vortec will interchange with the 305 vortec or any 350 with the 305 vortec? The 305 vortec uses a conventional small block Chevy style large starter. The 350 vortec often uses a high tourqe mini starter. You can interchange them. The mini starter is preferred as it saves space has more torque and normally last longer. Now if you're talking older starters interchanging? Some of the older small blocks used a diagonal bolt pattern and different tooth count.
The eight digit in the VIN # will tell you what engine you have. If you have the number 8 it is a 5.7 (350)
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
