casting number on the back of the block on the driver side write it down then go to mortec.com you can also look at the harmonic balancer if it's made of metal n rubber it's a 305 if it's solid metal it's a350 but it not always accurite because it could have been changed but that's rare.
no
Depends on how the motor is set up.
by the dispacement
the biggest difference is obviously the stroke and bore of the engine and the size of the engine
for the 2004.5 they upped the hp in the H.O. motor to 325 h.p from 305
On the drivers side of the engine in back of the cylinder head there are casting numbers and next to the casting numbers are raised letters either 5.7 or 5.0.
Nothing.
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.
The intake valve is bigger.
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)
between $100 and $200.
