512 B Underway
Picked up an assembled longblock 400 last week and after disassembly and degreasing in the jet wash--blasting took care of the paint/rust and really caked on muck. I really like clean castings to work with. Spent the morning on this block--removing dowels, tapping all holes, light deburring, clean up cam bores, stroker notches, enlarge oil pickup to 1/2" and since this is a manual tranny--I drilled the thrust bearing for oiling (1/16". I have a full 8 hours on this and the real machining isn't started. All pre-machining prep. I will weigh this one tomorrow. Some pics of the progress. J.Rob
