I would think this engine could easily make 250 at the wheels if it’s set up well. And the RS crank shaft should allow it to rev safely to like 8or 9k!
I’ve got a MFI 2.7 with L120/104 cams, twin plugged and 10.5:1 comp in my 74 Carrera. It’s a super fun motor. Would be good to know a little more about this engine build.
