Finally got the numbers off my so called 289.
After searching a while it seems to be a 302 from a Falcon. Is this correct? Is this a roller cam block?
My heads are stamped 289, which should be good for my compression.
Sounds like she has a mild cam as well, but who knows.
I have a performer 289 intake coming and need to find a Edelbrock 1406 to match.

Assuming you have the original pistons and early 54cc 289 heads you would still only have about 8.3:1 compression...If they were 1968 289 heads with the 63 cc chambers you would only have about 7.6:1..NOT good for power..The stock 1973-76 302 with original 58cc heads would have been 8:1..Again not great for power and part of the reason these motors had such low power ratings..

Maybe, maybe not...If the 289 heads are earlier than 1968 then they will have small chambers which are good for building compression...However 302s from 1973-76 have a taller deck hieght than earlier or later blocks...That may be why the previous owner swapped on the 289 heads,to try and get some compression back....
