sorry wade didnt mean to single you out.. your name was mentioned in a prior post on the thread and well... you are the poster boy for 283's right now
.
yes it appeared in the 90's im sure they meant to supersede 457 but 459 appeared and was in there 7 years or so before don quinn found it and used it on bill belden's 65 chevelle, and of course it will not go away now.
we 57-61 283 guys would like to have it ok'd for our use also seems fair...
captain jack
good luck at indy !
