What's your plan for lifters? I wiped a 6401 in my 383, but not sure if that was caused by egged lifter bores, or poor quality lifters. I followed all the break-in procedures.i also read where I should have broke it in with stock springs...
I'm building a 440 now, so I'd rather not have this...
Do not leave the stock spring in it. If your shifting it manually at any time it will not release the band fast enough and act like its locking up for a second (because it kind of is). It's not too bad of a job to do in the car, the worst part is getting the F$%#@^& snap in the extension housing...
