Hey all,

So here comes perhaps the most important thing I need to make sure is up to far for my upcoming motor swap - the cooling system.

The tired L03 is going bye-bye in favor of an L31 Vortec-setup (w/TBI), with a cam of some type, probably an LT4. So w/the right tuning and part selection, should be putting out around double the HP of the L03, give or take some.

Currently, the cooling system is stock, except for an aluminum 2-core radiator. Also needs a new air dam, but that will definitely be replaced!

Will the stock fan push enough air to keep things cool, or do I need to upgrade? Is a single fan fine, or must I run duals?
