Did a little more to the dummy motor.
the cylinders are painted with model masters semi gloss black and glued to what I believe is the coolant porting tube. then I cut them all even on the bottom, sanded them and glued a piece of cardstock below to hold them together.
I started test fitting some pieces for the intake. I’m using plastistruct butyrate plastic tube and elbow fittings to make it easy and it’s pretty light. It’s slightly heavier than the styrene, but more flexible. Should make for good radiator pipes too.
