I bought my 51 3600 from ND and cost me 800 to ship to Michigan. In hindsight maybe I would've opted for 3100 because of the front drum issues . I paid to much probably considering the 235 in it was stuck. Ive got over 3 grand just in parts and its still down to frame with at least another 5k to go just to make her run. Having said that I look in the shed and see my front clip and it puts a smile on my face. Having restored a 76 17 ft. century Arabian runabout with original 351 ive learned to hide the receipts ...most times then not you may invest more then it's worth but having something that's rare and unique to me is worth the price of admission..
