Exactly what i was about to say. We swapped a mates 250 from an XD into his XE. In the XD it was a really smooth engine but really it was a slug.
When we dropped it into the XE we swapped the intakes over to use the 2 barrel webber and XE manifold and wow what a difference. It now has a 3.23 ratio diff and a dyno tune and for a basically stock car it goes really hard.
If your looking to get big power a redline 2bbl manifold can be yours for $150 if you want, PM me if your interested (and your in Melbourne) and a holley can be bought rebuilt from Hume Performance (02 9602 9033) for under $320 delivered to your local post office! This setup though, I will caution, might be a bit of over kill on a stock cammed engine, I would definatly look at getting a lumpier cam, otherwise you'll never use the extra flow the carb+manifold can deliver.
