okay guys, so first off I know this isn't the best choice for a ls engine but I got a decent deal on it (imo). The h1c came off first gen cummins. its the predecessor of the hx35 I think it flows slightly less. but I'm curious how much more quicker this would spool if I swapped over to a 12cm non gated housing vs the 18cm? I want to say it comes on the smaller of the two h1c's.
