if you have access to the engine block you can drill through that. remember- the top of the motorbis below the engine blockThere is not a whole lot of room. The body tube comes down over the motor tubes quite a ways and covers the end of the engine blocks, so the vents need to be above the bottom of the BT. So, the only place to vent is on to the fins. It is why I painted all the fins black, I already figured they were going to have to deal with a lot of exhaust gases.
Couple pics to illustrate what I mean. The blue tape marks the top of the engine block inside the motor tube. The vent hole needs to be above that. As you can see, when the body tube is installed, it comes down to the tape line, so any vent hole that takes advantage of the space between the fins will have to vent the gases onto the fins.
Open to suggestions if I am missing something.
