Hi, I am wondering if anyone has heard of or exerienced those Flathead engines currently available at Halibrand? They are suppose to be French surplus high output crated motors with 0 miles and "ready-to-run". Halibrand will not guarentee or warrenty these engines so I am wondering if a $3,000.00 invesment would be wise? I will appreciate any info someone may have on these engines. Thanks and have a great day! - Jerry.
