i did read your post, and i told you i wanted everything you said i would get from the 283....you did tell me to keep the 2 barrel, but i was wondering what else i could...i will check the heads when i get a chance...thanks for the site...sorry if it sounded like i was being dumb or a smartass...i do want to know what i could do money wise to put just a small bit more life into the lil engine...and i will be calling and ordering a cam that is suggested by the company when the time comes, so i won't ask what kind of cam you think i should get....
