I've back to backed a small and a big (careful what you say here!) on a ~300 hp engine and the big port was 10-15 hp better. That's pretty significant for a stock piece.

Do you have any idea if the 72 360 intake runners and ports are the same size as the 290/343 intake or not? The port openings on the 72 360 are smaller, but not by a huge amount compared to the #5532. I can't tell much about the inside runner size. Is there a noticeable difference in the 390 and 290/343 intakes just by looking? Do they have real small ports like a Holley Z or an Edelbrock SP2P? Thanks again.
