I can get the numbers off the 273 today it’s a little weird it’s got 318 written on it and the stamped crossed out and 273 stamped next to it but I will get the numbers for you. No adjustable rockers. I’m set on the ford 9in rear vs a 7 1/4 rear. I have the original ignition but I want the Msd distributor at least. Don’t have to have the box I’ve had a street fire die on me before. And yes the 318 was a running driving 318 with a 904 trans before I pulled it to put it in the swinger from my custom. I also have an aluminum radiator I would like to go back to.
