I use J10Y's. Hard to find though. Or go with Autolite AR32's. I scored a vintage unopened box at a meet for $30 for a box of 10. They won't be used and will be put on a shelf as a collectable. This picture is not my box, but are the same in an unopened box. I haven't tried the Autolite Racing AR32's yet, but I will on my next change.

Yes in a "conventional" 383 and I should have asked if his 383 had electronic ignition. Actually running J10Y's or AR32's in a BB with newer electronic ignition help the old cold plugs work ever better and don't forget--Cold Plugs Mean Hotter Performance! Just my 2 cents.
