that plate sounds like a stock spacer does it have two bolt type starter hole in it and a slot out the bottom to the crank hub ? ''yes it does because thats the stock early one that came on the motor from the factory'' . does it have dowel pin holes for the later model 727 in it ? '' no it does not , because it was made to fit the two speed trannies '' . lol . so i asked then answered them because . YOU HAVE A STOCK SPACER PLATE , i've got one in my hand right now . and it will not adapt to the later stuff . but it can be used as a core for someone to make an adapter from . so your not there yet . i'll call my bud and see what he has in stock to do your adaptation , if you like . i do early hemi's , to go racing with . have a few buds that have and do run them . what are you going to do with your low deck 354 hemi , and is it an indust block with wet carb heat heads or car type with exhaust heat to the carb base ?
