DapperDan, yes the 6.0L does keep you busy. Been great for over 100k miles.

So additional differences I am finding out between LT1 and LT4 is all centered around the blower. Different can shaft to support the forced induction with the lower compression ratio and forged aluminum pistons. All focused on being built to support the blower.

With all this, is there no stock internal high horsepower LT1s out there? So with no plan to pull the short block what would be a better route then? With the limitations of the short block should I even consider the fuel system?

LT1 builds don't equal lt4 builds till you change out the crank (rolled fillets), and add either Proflow intake valves or titanium as the stock LT1 intakes are hollow and made of steel. So there is more to a LT1 build than forged pistons and aftermarket rod bolts.

Trans, the LT1 Tr6060 is weaker

Shafts, all of them need to be changed

Diff... um there is gonna be ring weld failure at this power and traction level

Fuel system, the whole thing needs to be changes, so there is no difference here.

Clutch the Lt4 has a better clutch but really you should go aftermarket add 2000 to 2500, Katech has a nice billet flywheel which will save you 20 lbs.

So as stated, these is nothing that can take that power stock and bolting on twins till something blows up is not my cup of tea.
