The guys that are running 292's in the 800-1000 HP range say they shift at between 4500 and 4800 RPM.
I love what some of these guys are doing with the inline six, no doubt that power can be made. As with most of these engine they are very exotic, the key is getting it to breathe. Most use a highly modified or a hybrid aftermarket head and some turbo or blower configuration... Growing up my Father had a friend that ran a 300 inch Ford on alcohol in an altered Anglia, very competitive... I just did't think that a street driven 50' PU owned by a 20 year old needed all that.
