How well off is the 400? If it's in good shape, you could alllways pull some on the cheap tricks to get started. You know, bolt ons and a cam, hi stall converter w/gears and some suspension work.
The guy that sold the charger and newport started the newport and the 400 ran smooth as silk, not even a tap on startup. It's going to get all the goodies you can bet plus a stroker kit. :thumblef:
