If/When you go to siamesed Intakes?
In a conversation on Sunday, One of the evil influences, which shall nameless("ZZZZZR1") started talking about siamesed intake ports for a 385 cube engine. It got me wondering, when & what parameters to use this method. I do comprehend the concept of drawing from 2 ports. I am sure RPM & Engine Size dictates use, just curious when. And, if cylinder porting would be different. I doubt I would ever do, just curious how it is used. Thanks, Tim

I have one on my 350 w/cams.....have not been to the dyno but trust me no loss in torque.....pete drove it as well and came to the same conclusion. In fact, someone put it on a lift and checked the revolutions because they thought it has a 4.10 gear.

Siamesed and dropped plenum on a 385 is sexy. We need to meet up soon
