Thanks bullfrog, Yeah, I don't want it to be to pretty but useable. Most 8000 Louisville's down here had Cat 3208's, (Clarke 5 speeds) which wasn't a bad motor if they were looked after but personally I don't like em due to not having liners for inframe rebuilds. Basically a throwaway engine.
I bought this because the farmer (2nd owner) who owned it before me, had hot rodded it, changing the complete engine drivetrain with a 6V53 (bigger injectors) two stroke Detroit, 10 Speed Fuller RTO 6610 and a single speed Rockwell R170 rear axle.
Love the sound of 2 stroke Detroit's, plenty on youtube if your not familiar with them.
As a kid I always lusted after a LN Louisville and for me with the 6V53 I consider this icing on the cake.
