Introduction: Working 3d Hemi Based V8
I built this because I wanted to
design an engine loosely based off the 426 hemi created by mopar to rule the racing scene in the 1960s and 1970s. The engine has a .889 in bore 3.7 deck height and is currently in the short block stage. I am constantly redesigning it to make it better.
When the engine is finished it will be a working supercharged 3d printed hemi.
first I took the dimensions of a hemi and cut them down to a scale that would work on the printers i have access to. after the dimensions were all recorded and written down i set to work design and drawing the block
the block has
.889 cylinder bore
1.2 inch main journal diameter
.75 inch cam diameter
then i designed and printed the short block.
the pistons feature a
.44in wrist pin
1.1in connecting rod
.3 in thick connecting rod
the connecting rod journal is .3 inches
- main journal is 1.2 inches in diameter
the crank also features a .8 inch stoke the stroke is limited due to the camshaft's position. the oil pan was design and built with a largeder stoke in mind
the oil pan is 3.8 by 6.6, and 1.4 inches deep at the bottom of the pan
We have a be nice policy.
