Hi UKIE

K&B Green head torpedos are mid to late 50's vintage and with the exception of the 29S were basically F/F engines which means they rev which is not really what you want for C/L stunt. The 29S was the standard K&B 29 G/head with milder timing produced to take on the Fox 29 and as an alternative would be the best of the bunch for C/L use.
