i bought a 525 from him a few years back, when it arrived at my home it was in a nice crate and it was complete with carbs and ignition and was ready to go. once it was installed in the car it fired up the first click of the key,i followed the instruction john had included with the motor, it is oil tight and runs great, is perfectly balanced and although i havent had a chance to drive the car as i am sorting out the trans problems ( 4 speed wont come out of reverse cleanly) but i feel the motor will be exceptional, john states, with the 4:10s it just may wrinkle your car up a bit ( so i put in the full connectors)i must also add that the carbs were dialed and feels really crisp and the ignition was dead on. this sumer i hope i will be able to spend some time behind the throttle, stupid trans!!!!!!1
