The one down fall I have heard on these motors is the valve stem size and running a bigger spring pressure for bigger cam for drag racing. But I know they, valve guides can be made bigger.

I think that is the biggest down fall of these motors for drag racing. A cam change, better intake, bigger carb, a little off the head to up the compression and you can look in upwards of 1000hp. If given the time and effort you could have a killer set up.

Only issue is the limited amount of trans stuff. Jesse is the only one I know doing some sort of adapter.

When my project is a little more firm I will reveal what I am doing and let the nay sayers tear it apart.
