I recently finished putting a 460 in my 92 F150. I used an engine from a 91 FI and the heads, intake, and carb from an 84. I am very impressed with the performance (possibly cause I am used to the 302) Durring the build i noticed that the FI pistons are shallower than the carb ones. I figured that the difference in the heads probably make these two engines close to the same compression ratio when stock. I was wondering if anyone knows what the compression ratio is with the FI pistons and the carb chambers?

Another thing, Is there a difference in the camshafts in those two engines?
