Have you done this conversion yet ? Where will you get the adapter plate kit for the 351 swap ? I hope you will post pics of the process & completed project . I am hoping to do a flathead v8 100 hp conversion before the Lord takes me home . My engine is ready for a machine shop as soon as I find a reputable shop to take it too . I got ripped good when I had my 1952 6 cyl OHV engine machined . They quoted me one price for an engine ready to be installed into my 1952 8n . But when I went to pick it up , the price was double , they loaded a bare block & everything else in boxes into my truck minus pistons , rings , gasket kit , & all the bearings needed . Plus they lost my fan blade hub assembly . So, this time I'm a little more conservative about a shop . I hope to see your completed project soon . God bless , singleken45
