Try $2200 . Im just waiting for mine to be finished which will be matched to some MAST med -bore LS3 heads which will be going onto a solid roller 408

Woops. Still, if you need it, it beats the **** out of $3500+ for a sheetmetal intake.

Here's a similar question. I'm assuming that with the LS3 hollow valves you can run less spring than you need with the L92 valves. Is there any drawback to the added spring pressure? If the car has upgraded pushrods and has the harland sharp mods to the rockers, there's really no issue is there?
