Inline 6 292
I like the 292 inline 6, good engine. gobs of torque, and with a bit of massaging can give you lots of HP. biggest limitation is RPMs, Depending what mods you do to it 5500 to 6500 RPM. 1 hp/cu inch is easy to get and reliable. Radical mods have yielded 1000 HP with this engine. So it is a good engine. Don't throw it away.
