| Post subject: | 997 or something else? |
Im just trying to identify an engine i have sitting in my workshop, any advice i can get would be helpful. The block has very few markings except a 12a497 on the side with a stamped number 1015/5164 on the top face, The head has no markings were they should be except a ECAM4004 on one end and up near the waterpump end it has 4 C7 or a 4 G7 that i couldnt quite make out, this didnt match up with any book or online reference. I then measured the bore it was 62.45ish with the vernier and the stroke was 81.5 also with vernier so might be a few thou off, this matches up with a early 997cc cooper. is there any other marks or identification i can look for? Any help with this mystery would be most appreciated John |

The head has no markings were they should be except a ECAM4004 I believe the 12a497 casting was common to all smallbores, 997 to 1098. Can anyone else confirm that? A 1015/ series engine number is a late Oz 1098, up until circa-1975. I think the CAM4004 was the smog head fitted to 998's? |

Simon is correct... ^^^ 
It could have a 997 Cooper crank in it if that stroke is correct. They are pretty much a 1098 crank dimensionally with slightly less stroke. No stronger, or weaker. Just rarer.... Unless that smog head has been well worked over with big valves, it will go better with a 12G202 (1098) head or better still a 12G295 (cooper 998) one. |

Goldbrocade means does the block have a hole for a mechanical pump, or is the pump still bolted onto the back of the block?
