Same bolt pattern, the only difference is the torque they put out. Most of the 350s will be of the High torque. Look at the starter solenoid where the wires hook up. On the bottom of the solenoid look for a copper tube like extention. For a high torque it will extend back towards the end plate. The regular one is more on the main body of the starter. If it was me I would just stay with the regular. 305's dont' need much umph to get spinning.
The starters are compatible with both engines, just the 350 starter will probably put out more torque than the 305.
yes, a 305 and 350 utilize the same block
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.
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.
The harminoc balancer. The 305 balancer is thin and the 350 is thicker and heaver.
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.
no
No they are the same blocks.Where did you get the mounts on the 350 from? The 305 or junk yard?Is it a new 350 or older 350?
20HP/ Horsepower. The 350 has 20 Hp more.
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.
Depends on how the motor is set up.
5.0L is a 305. 5.7L is a 350
