Re: Boring Lunati makes a crank in a 4.250 inch size now so things are getting to the point were your gona run out head. Its a small block head and cant support that many CI unless you force feed it.

Re: Boring I just emailed Lunati Tech support a few days ago and they no longer are making the 4.25" stroke crankshaft, at least that's what the tech guy said.
