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 harminoc balancer. The 305 balancer is thin and the 350 is thicker and heaver.

no

the only real difference is the head

20HP/ Horsepower. The 350 has 20 Hp more.

The starters are compatible with both engines, just the 350 starter will probably put out more torque than the 305.

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.

Try a search for vortec engines

No. The bore size is different between a 305 and 350. The 350 bore size is larger.

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 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?

The bore and piston size are the only real difference between the two.The 350 has a bigger bore and piston and so puts out more horsepower, the305 = 3.75" bore and the 350 = 4" bore. Both have the same stroke.Also the starters are different because of the smaller flywheel but other wise the external parts are interchangeable.

The 305 & 350 are basically the same engine. The 305 just has a smaller bore(3.736 vs. 4.000), not quite the power or torque, but durability should be almost identical. It is more costy to rebuild a 305 than a 350 due to the popularity of the 350. If power is not an issue then go for the 305 if you can get one cheaper. If you want more power, then a 350 is the way to go.

yes

yes... some rs camaros came with a 305 and the only difference between the 267, 289, 302, 305, 307, 327, 350, 400 sbc is the stroke and bore. the block itself is essentially the same.

Nothing.

I believe the 305 TBI was in the RS models. the Z28 had 305 ad 350 TPI (tuned port injection)

5.0L is a 305. 5.7L is a 350

The easiest way is to look at the Harmonic Balancer. The 305 has a wider thicker balancer than the 350. Pus the timing tab on a 305 is located ON the timing cover and the 350 is bolted on the with the cover bolts. Riky9

350

If you are asking if you can substitute a 350 for a 305, the answer is generally yes.

ON LATER MODELS LOOK AT THE REAR OF THE BLOCK NEAR THE DISTRIBUTOR AND IT WILL HAVE 5.0 OF 5.7 CAST INTO THE BLOCK

305 TBI IROC HAS 350 TPIno such thing as a 91 iroc camaro. rs had 305, z28 had 350 im not sure if the z was available with the 305.

yes, a 305 and 350 utilize the same block

Instead of having a 2.8 v6 or non h.o 305. It would have a 350 tpi or high output 305. It would have a different spoiler , suspension , and have formula stickers on the doors.
