Hi
Recently purchased a late 1966 Coupe that was an original big block. This is evidenced by the correct dated BB Rear, gas line, Hood prop, tach, oil pressure, fender flags, correct radiator, heavy duty half shaft flanges, etc. Without owner history is there any way to determine if this was a 425 HP car or the 390 HP car. Car had been stored since mid 70's. I've heard that on the passenger side firewall if it was a 425 HP car there should not be the 4 rivet/holes for the overflow tank. I have four indents, but no see thru holes. Is there any truth to this? Thanks
