Yes, but running a 350 cam with 305 heads is not effective,you need to run 350 heads as well. In order to benefit from a 350 cam you need something to flow that extra fuel and air, so using 350 heads along side of the 350 cam will be the cheapest and best choice. HAVE FUN!! A 350 head can physically bolt onto a 305 block. However, 350 heads can have the valves extend into the cylinder and contact the cylinder wall (even with the smaller 305 cam). The 350 cam in the 305 with stock heads will work. You wont want to use 350 heads you will lose compression due to the largers combustion chambers.
The headers for a 350 and 305 are the same.
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
the block & heads are the same you just have to pull the 305 out & put the 350 back in
305 heads of course, 350 heads will fit for sure and possibly 400. obviously no big block heads will fit. a 305 with 400 heads gets you a little over 352. 350 with 400 heads is a 383. add and divide
Absolutely. Many (if not most) 305's came stock with a 350 turbo bolted to the back of them.
stock 350 heads are 72 or 74 cc
You will need to have the heads for the 305 bored out to the same size as the 350. I disagree: you can use the 305 heads on the 350 block but you will increase compression as the 305 heads have a smaller combustion chamber. The critical dimension is valve clearance. If compression ratio is a critical consideration, different pistons may be available which will bring the combustion chamber back to size. the 305 is from the 3.671 inch bore family. The 350 is from the 4.00 inch bore family. All small block heads have the same bolt pattern.
No. The 350 has bigger valves. While you CAN put the 305 heads on the 350, (I can't imagine why you would actually want to) you can NOT put the 350 heads on the 305. Because of the 305's small bore, the valves on the 350 heads will hit the cylinder block.
Hard to say without more information, but in general the decreased compression from the larger chamber heads would probably drop it 10-20 hp from stock.
As long as the 350 is older then a 1987, you will have no problems. They will bolt right on with no modifying.
If the Buick 305 is really a Chevy 305, then the motor mounts will interchange with a Chevy 350.
That depends on what type of heads are on each, and the year it was built.
a Chevy 350 crank is a Chevy 305 crank. they have the same stroke, 3.48 inches, and are interchangable. swapping between the two cranks does not change the engines displacement
5.0L is a 305. 5.7L is a 350
No. 305's have small valves due to the 305's small bore. Large valve heads can't be used on the 305 because the valves will hit the cylinder block. 350 heads breathe MUCH better than 305 heads. Stick with the 350 heads.
The 83 Chevy C10 comes with a 305 but not a 350. The 350 is an option on the 3/4 ton but not the 1/2 ton.
If you are asking if you can substitute a 350 for a 305, the answer is generally yes.
They are basically the same heads, If the 93 350 is a vortex motor.
Oldsmobile used Chevy 305's. 76 350 rocket 77 305 Chevy
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.
Not a good idea. 350 heads will lower compression to 7 to 1 or less.
Depending on years that you are swapping around....yes. The 305 heads will raise the compression of the 350 considerably. However, the intake valves are a lot smaller than the 350.
