I've read a little about the older 216-261 inliners. From what I've read, they're a low compression, low rpm boat anchor. I'm not saying they're not cool. I dig the o.e. stuff. I'm just curious why there's no turbo build threads, or anything but a different head added to these motors? Maybe there is no way to hop these things up?

Hollow65,

I am just now starting a hop up project for my Apache. It is going to be a .040 over 261 with a McCullough Supercharger, mild cam, and an 848 head. I am going to use my current EFI setup modified for a 2 bar map sensor. You can follow the build here if you are interested.
