It's the the maintenance due to being a stroker. It's the maintaining the tune with the carb with the cam that will support 550-600hp in a 4" stroke SB combo. It's more than time, it's the knowledge too. The stall will help though.
What takes this out of the average person is the costs involved to actually utilize the 550-600 horsepower on the street.
What was mentioned:
- Caltracs
- custom 904 built to take 550-600hp
- double adjustable drag shocks
- good 8" stall converter
- good valvetrain to support cam lifts that provide 550-600hp
- Dana rear end?
- Driveshaft that supports 550-600hp
... the incidental supporting cast of parts have some expensive bills
