I am in need of a new carb for my '02 426 and from everything I read it's just best to upgrade to a 450 carb. My question is what exactly I'll need to complete the swap aside from just the carb itself.
I have searched and read a bunch of different threads but none seem to give a good detailed description. When looking at pics of the 450 carb on ebay, it doesn't look like the adapter that goes from the carb air intake to the air box on the 426 will fit it. The one on the 426 has bolts on either side. It looks like this adapter does not exist for the 450's. The 450's look to me like they just go straight into the air box boot.
If anyone could clarify this for me with pictures and/or part numbers I would highly appreciate it.
Here is what I am talking about:
426 inlet side:
450 inlet side:
450 intake boot which appears to mate directly to the carb UNLIKE the 426:
Thanks for your help!
