Traditionally, engine changes have not been permitted in the Spedeworth World Final other than as per the ORCi rules in terms of changing engines between mk.1, mk.2 and now mk.3 Granadas, or by substituting a 2 litre pinto engine into any unlimited car.


For 2010 (Ipswich 23rd October) as an experiment we will be allowing a 2.0 Zetec engine to be transplanted into frog-eye Granadas only. Other rules remain unchanged, any drivers in any doubt please contact the Spedeworth office on 01252 322920, or ask Nico our National Banger representative.
