L31 intake manifold flow
Hi does anybody know what the intake volume, length and airflow is for the L31 intake manifold 350. Has anybody ported it for more flow and how much power? Are there any other mods for or is it is what it is?

Best bed would be to change it out with the marine intake or something else that lets you change your fuel injectors too. With the stock intake it is maxed out at about 400hp, as the highest we have seen is ~330rwhp because it only allows us to use stock injectors. If you insist on keeping the stock intake you can get the spacer for it, which is NOT a simple throttle body spacer.
You can search google for the Vmax intake spacer, which is what I think it is called. Check my sig and its in there.
