Hi All. new to the site. I have a 1978 c10. Can anybody help with the engine specs of my motor. the code at the starter is B 25 8 CON 2 377127 there is also an code at the distributor. FO228 GAR, the number below that is 816035( appears to have been restamped.) I know the 78 models has a intake moulded into the head.this appears not to be the case withmotor. is this strange?where engines with this modification exported to south africa?
