what is the biggest cam you can run in a sohc neon without changing pistons. And is a 10 grind cam gonna make a neon sound different?

RE: biggest cam
You cannot.. actually you can butyour car will be worse off if you ONLY drop the largest cam you can find in your engine.
What a lot of people do not realise is that parts must match up in order for a car to perform. For example if you drop some huge cam in that motor then you had better be doing some serioushead work at the same time. You need to 'feed ' that cam and keep the motor breathing out the spent gasses.
Imaging having your but sewn together and dining at a buffet for72 straight hours. You can burp all you like but somethings gonna give!
Just for a start theinduction needs to be improved,valves need to be bigger, stronger springs ; flow,port and surfacethe head,tune the exhaust. Then we need to move on to the transmission.

RE: biggest cam
Here is some good info...

The SOHC cam choices we have are severely limited due to the construction of our heads. Instead of the traditional cam cap setup, we have solid cam journals machined into the bulkheads on the head, and they are pretty restrictive on cam lobe sizing. There are ways around this, such as lowered lobe centers and lash caps which is used effectively on only the largest SOHC cam (crane 15, haven't heard of the official designation for it, but its .400/.400 lift, and 232duration@.050 lift on both sides). Some other methods have been tried with limited results, and the results usually were not real reliable for street cars.
