The LPE package cost in the region of $30k - give or take - someone here could probably narrow that down a bit - the point is
you want a serious all motor - it costs. There is a reason for that. The time it takes to build a top quality engine is huge - very few understand this.
From what you have posted (correct me if wrong) all you are doing is what 99% of what everyone else does... i.e.
ASSUME the factory longblock is all you need - expect to bolt on heads, cam, intake and exhaust - and go record hunting... maybe add better pistons etc and think that makes it a race engine.
WRONG!
The factory long block is great - but it will not get you to records on all motor.
To run race quality parts, a custom top shelf specification, and full blue print and balance - get your check book out and empty that V10 of almost everything and start again - then go break some records.
That would be a really cool project, one I've thought of a lot too - but there is no cheap way.
If you want to keep your basic bottom end or within a tight budget - forget asking questions about "who makes the most etc" then hoping your car with bolt ons and add ons and a rebuild can be like that - it won't be even close.
Sorry for the dose of realism - the engine will still make great power with the usual mods. If you do not mind the odd lash adjustment - solid roller lifters will open up a new world for you if you get a grind from someone who knows what they are doing.
However - if you are willing to spend the big bucks to have it done right - the possibilities are endless.
9's on all motor are a given, the only question is who is first. A built engine will last longer than a bolt on if done right - but don't expect 100,000 miles from a 700rwhp motor - half that would be a great effort.
