okay, "under ratted for insurance purposes" is that GROSS or Net power? GT 350 & 500 & cobras were built by shelby american, not ford. ford took over in late '67. and how much after inflation is that 69 zl-1? also, it was not avaikable to the general public. yes, i have rebuilt both chevy and ford. an engine is an engine. the corvette reverse rotation water pump will not fit all chevys, nor will the pieces from a 262 or 273.
