Quote: No not at all, by restricted exhaust I mean where the benefits of overlap are negated by backpressure like from manifolds or tiny headers. Combos like that need wider spreads, later ICL's and the intake tract need s to pretty much 'fend for itself'
For the 430 the TTI's and a nice 3.5 to 3 dual system would be perfect, x pipe would be a plus but not a necessity IMO.
This is where I have to disagree Wizened. Even in engines with restrictions in the exhaust,I see benefits with tighter lsa. I usually find that an engine size favors a certain lsa regardless unless compression ratios go way up. There are minor exceptions,but more often than not this is the case. Even my stock small block I'm testing favors a narrow lsa,with its small exhaust ports and headers. Keith
