289 heads give you 1 full point of compression over 302 heads due to the smaller combustion chamber.....should run great but you will have to run at least 93 Octane all the time.

looks like a holley 650 dual feed double pump like I used on my 83 302 motor when I converted to a 4v.How do you know they are 289 heads? I saw no numbers. Could be 260 heads(serious compression ).

we broke the otor down to find out they were 289 heads but had alot of stress cracks so lots of time and work went to putting everything through a machine shop now just going to build a new 302 w/ what parts i can use of the old block
