I have a westfield SE kit car that is powered by (i believe) a 1600cc Sierra Pinto engine which has been bored out to 1700cc. I would like to do some work on the engine but i don't know the year of manufacture of the engine or the actual verified model.
Also i was wondering if the fact that it has been bored out would make any difference to any of the parts i.e. spark plugs, distributor etc. etc.
The only information that i can find on the engine are the following numbers
I would be very grateful if anyone could decipher any of the numbers above so that i can find out exactly which model / spec the original engine was
Also when i do know the engine model i would also be grateful for any tips for how to up the performance. The car already has twin 40 carbs and a fast road (or rally) cam.
Many thanks in advance for any help
