Can a 305 be bored to a 350?
no
Will Chevy 305 heads fit a Chevy 350?
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.
Do the 305 vortec and 350 vortec have the same heads?
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.
How many horsepower will a 350 40 over engine with 58 cc heads generate?
305 heads work on a 350 engine
What kind of hp could you get from a 350 block bored 60 over a 400 crank with 305 closed chambered heads?
Depending on your intake system, you should be anywhere from 360 to 380.
Will 305 heads make more horsepower on a 350 1990ish motor with carb conversion?
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.
Are tbi 305 and 350 heads the same?
no
Can 305 heads fit on a 350?
Yes
Can you run a Chevy 350 cam in a Chevy 305 with stock 305 heads?
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.
Will 350 heads fit on a 355?
YES, A 355 is just a 350 bored 0.030 over very little difference.
What small block Chevy heads can you use on a305 4bbl Chevy motor?
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
Will 350 heads on a 305?
Not a good idea. 350 heads will lower compression to 7 to 1 or less.
