Introduction: K'nex V8 Engine

this engine was my smallest engine yet, I also have a intructions video on youtube for this engine. GOOD LUCK BUILDING!!

Step 1: Crank Shaft

the first thing!!

Step 2: Pistons

compact pistons, yet easy

Step 3: Crank Case

do not fill with oil!!

Step 4: Cylenders

for the pistens.

Step 5: Cam Shaftand Pushrods

the red conectors for the push rods should line up and stand up acuatly for the next step.

Step 6: Finishing

Step hardest step, and last step!!
