I have two of the 60mm listed on that page on an LQ4 and LS9 cam, blow through and no intercooler, and they spool alot faster than I thought they would.

thanks so i should be fine if i stay under 400". I guess what i really want to know is if I should get the 4" bore or 4.125" bore block

It really depends on what rpm you plan on turning and if its a race only deal where you want to max them out or more of a street car. You could go either way and make alot of power, they definitely have enough turbine for a 400".
