Hi, Hoping you folks can help me out with some information. My engine tag is as follows. Top line: 390 69 1 Bottom line: 9 C K 383 S The engine isn't the original in my Talladega. The intake appears to be a 390GT. The heads come back with casting numbers that don't preclude the possibility that there 390GT. Date codes are all 1969 so I suspect it's a factory Ford replacement or from a Mustang donor.
No 428CJ unfortunately. Any help is appreciated. Thanks, Dave 69 Torino Talladega, 79 Ranchero street rod
