1991 200 big bore kit

[tannaj2]

Well I am working on my project. I have thought about putting a 220 big bore kit on it and they will do other mods to the the motor. The question is a 200 with a 220 big bore kit would it be the same as just having a 220 stock motor. I am having forward motion do the engine work. I was going to do a 240 kit but Eric Gore said that they have a lot of problems.

No, the cylinders have vastly different porting to start with. It will likely be a 225, which you can search about on here...

A 1991 model with the 223cc kit?? He told me the valves were too close. Is this without the valves??
