Realistic valvetrain expectations.

Pascamp said
Some further info. My expectations are 600hp gross(give or take) at 6500 or less, don't care about torque (car is 2700ish). Good machining and tolerances will be used, along with modern cylinder finishes, coil on plug, tbi, and overdrive.

I basically want to be able to live an LS lifestyle with a BBM. Turn the key and drive to New England, drive it to the office, take it to test and tune 3 times a summer, and only pop the valve covers every 10k for a valve spring check. Is this a pipe dream?

Just copy the low deck that I built for my Duster. It makes 600 hp and 600 ft-lbs of torque on pump gas. EFI, coil per plug, hyd roller engine. You'll need $20K and an experienced engine builder.
