    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

550 upgrade question

In another post someone said they were machining their 550 case to fit 650 cylinders to it. Is it possible to do this for 750 cylinders, and what kind of stress would this put on the 550 bottom end, and the frame?
Thanks,
Billy
 
Just curious but wouldn't it be easier to just take the 650 engine and stick it in the 550 frame? would this work with the 750?

What are the benefits to the other method?

I believe the 650 is a shaft drive so I was under the impression that you couldn't put it in the chain driven 550 frame (at least not without alot more work, if at all.) Also, in previous posts I was told that the 550 frame is too small for any of the larger engines.

Back to my previous question, if 750 cylinders wouldn't fit would 700 cylinders? I didn't know until just a few minutes ago that there was a 700.
 
700 and 750 cylinders are the same. The only difference between the two motors were the crank, rods and pistons. The 700 pistons had more of a dome to raise compression due to the loss of stroke. Slightly different cam specs between the two motors also.
