I want to say it was heavier weights and lighter springs.
as for the link on Hot rodding your HEI Distriburator, I went there, read it, printed it off, and read it a few more times. Its good info I just havn't had time to implement said knowlege. Not to mention its cold as heck outside so my ambition level is low. =)
So should I do the timing before messing with the jets? (EDIT: Just read the last line of the last post, please ignore this question....lol )
