    A Body gearing

    So it looks like my 60 yo butt may get a job again, after 2 years. Quick lowdown; 70 Duster 340, purple 234, .484 cam, pistons .017 out, ld4b, 727 reverse manual with 3500 stall. Hasn't left jackstands since work started in 1987, 10 pt cage. So back then, I put in a narrowed Dana spool, 4.88. 4...

    Pully alighment, and more

    I installed new clevite hyd lifters on an old cam. In the 20 minute process, saw temp rising, shut it off. So, the SFI balancer puts the pulley out further- 1/2" from the water pump; 3/8" out from the alt. Will double groove pulleys get me close? Or all custom now? 70 340. And the alt, with new...

    Break-in new lifters

    This is going so slow. Found the last factory right bank piston left for a 70 340, finally found rings, they came .060 over; standard set coming next week. So, found the lifters leak down after weeks of sitting, even ones under no pressure. bought a set of sealed power; half wouldn't pump up in...

    just had to mess with it

    So, while buttoning up for the trans, swap; I had the idea of putting a dial indicator on the valves, trying to figure out what cam was in it. Pulled the rocker shaft, put gauge on it. Then when torquing the shaft back down- about the time I decided to back off, as one bolt wasn't right-snap. To...
