I still have a couple pairs of Desoto Intake Spacers for sale that allow you to run any low deck intake on any tall deck engine. These are custom CNC'd from aircraft grade aluminum and and are very nice pieces. I use them to run an early Edmunds 2x2 on my 341". ( FYI- this setup works very well. I have about 5000 miles on it now) $150. US/ Pair plus shipping. Note- the spacers for sale do NOT have "341 Hemi" machined on the side like the ones on my car (see photo). All you need to add is 2 sets of intake gaskets and longer bolts. Thanks for viewing.
