Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
what is a bi-modal intake and where is it located and look like, compared to the bimodal exhausts?
Marginal engine tune differences, extractors rather than log headers along with some other minor things. But probably the largest difference is that Holden use a different horsepower measurement standard than HSV. The slight variation in standards would mean, like for like, HSV would show a larger KW output (can’t remember the standards though, maybe SAE gross verses ECE net but probably a footnote in the brochures... as is, comparing PS, CV, CH, HP, KW all depends on what standard was used for measurement, whether gross or net, imperial or metric... it’s a mess...).

Best to simply buy the car you like the look and colour of and can afford as you’ll likely mod it anyway. So the starting point, engine wise, won’t mean much in such mod scenarios
Yes in the motor vehicle world, Holden 304kw = HSV 325kw
ok thanks. I think I found another thread showing something is different and might be worth the purchase and removing the flap so it is constantly allowing more airflow?
