Here's a calculator that I have used before...........not as "user friendly" as your chart, but still fun to play with!

I think you are right...87 to 93 is 60mm, pre 86 is 58mm...and I think some of the non performance applications were as low as 55mm. '93 Cobra was 65 and all SN95's were 60mm. The purpose was really to compare sizes vs. airflow and hp...not so much vehicles. But I will make this correction on applications. I also think 5.8 trucks and Lightnings were twin 50's. I will repost with the changes and add the 58mm.
