1963 Valiant Wagon "Candy girl"

You might want to think about the k frame lowering blocks, ala Hemi Barracuda and Darts. The 225 has the higher deck, translated less hood clearance. So a dropped base, offset Long Ram cleaner, something like that will be needed. Can't go too big diameter as it gets close to battery + terminal.
Here are a couple linkage images. Bracket and a long rod. Notice the jog for the 225 VS 170.Ebay_Intake_Linkage_II.jpg Ebay_Intake_Linkage_IIII.jpg Throttle Bracket 3.JPG
