All the 'tricks' aren't disclosed, lol. Truth being I'd like to see Indy revise the lower casting because if this works you'd think it would sell at a premium price. Thought myself about making 'insert kits' a guy could rub and then epoxy together because...it's probably going to be better than a single 4 no-matter how bad I am.
Do you think the same idea/theories would work on a Six Pack Modman? I'm sure each engine is going to have it's own specific set of requirements, but was thinking about how to kill some of the plenum on a 500" street motor I'm putting together.
