RC Scale Engine - Ford 640 Hemi

thingiverse

I scaled this loosely referring to the original Bigfoot 1 Monster truck 640 Ford Hemi engine. Triple Predator carbs of course but also included injector hat that you could use in place of it. You need to use a rubber band or a 171mm rubber timing belt for the pulleys. Recommend that you gently test fit each printed part, then dissasemble, sand, fill primer, paint individual pieces to your liking and then glue parts back together. Some like superglue, I always like to use E6000 because its more forgiving and not permanent. Also note that the holes in Block 1 with the long backs on them (For Pulley Shafts) will need to be enlarged with a 23 Drill bit. Tip - Use electrical wire and small hoses etc to further detail engine. 11/28/2019 - Updated Block 2 and 3 from .3mf files to .stl files. And added the front portion of the blower injection hat (This snaps onto the main hat body) It helps if you want to make moving butterflys - There is a pass thru hole for a paperclip wire to pass through. Also added photos of exploded view to aid assembly 3/10/2020 - Updated Valve Covers to offer two styles
