    68 427/400hp original engine?

    I recently bought a 68 convertible and I'm trying to determine what engine the car originally came with. It currently has a 67 396. I removed the gas tank, but found no tank sticker. It has original front and rear sway bars, 7 leaf rear spring, the tach has a 5600 rpm redline, differential is code AU, muncie 4sp, the fuel line has no return. Does this sound like a 390 or 400? Any help would be really appreciated. Thanks Scott.

    Re: Either

    the 400 is nothing more than the 390 with three two's. In fact, if you ordered a 400 hp option, i believe it shows the 390 engine on the line for engine and the 400 as the option.
