I've been pondering the same thing. I will be installing a 261 in place of the 235 next winter and will be showcasing the engine w/ a 2x1 intake. That means no oil filter on the intake!
I'm thinking a custom set-up MUCH like the third pic from Curt B.
I still would like to see some pics of a firewall setup if anyone can post. Thanks!!!
