Happy new year Mope folks. After finding out the less than good news that my motor had no oil pressure, the engine's now been pulled out and partially stripped.
The good(ish) news is that we found the problem - bent pushrod and follower. Chucked replacements on there, span up with drill and full pressure. Hurrah

Whilst there we saw the core plugs were kippered and the water pump pretty noisy. Crank looks good. Cam a bit hurt from follower incident so Ricky is sticking a new one in along with new gaskets, follower set, pushrod set, bearings, water pump and probably HT leads with an electronic ignition. Ricky's going to powder coat a few brackets and things too, to make it look 'right'. Talking of which, can anyone direct me to some good piccies of a proper factory looking 383 4 barrel engine?
Photos on their way of engine rebuild thus far.
PS: Do LUMENITION do a good electronic ignition module for Mopar dizzies?
