Alright Boss, break a leg. Please come back and post pics and dyno numbers. I'd love to see you make 1200 hp with a V6.
Will do, it's a summer project just buying parts now

"apparently the intake gasket is leaking some fluid so it definitely needs a rebuild."
Umm... better check your muffler bearings.

4.2 liter = 256 cubic inches. 600 hp / 256 = 2.34 HP / CI. That's huge. More than mythical, some would say. You're talking professionally built race engine levels.
Trying to fake it on the internet is pointless. You can learn a lot though, so you don't have to fake it.

"And in case you were doubting that EFI University lacks the know how to show you these things, check out this video as one of their class-built engines makes 757 horsepower with just 381 cubic inches of displacement without a power adder, and all through ported stock casing 243 LS6 heads no less! That puts it just five ponies shy of the mythical two-horses-per-cubic-inch mark."

"For example, a 540-cubic-inch big-block that produces 600 horsepower is making just a little more than one horsepower per cubic inch. That’s a relatively mild motor compared to a racing engine that makes more than 2 hp/ci,"

Edit - I got the urge to post this after seeing the "bud" post, which has since been edited away. Still counts though.
