I got this information from the Fat Man Fabrications website:

"NAPA #277-3039 ('74 MII 4 cyl. w/o air)
33-34 Fords, 33-35 Chevy
NAPA #277-3036 ('78 MII V-6 w/air)
35-48 Fat Fender Cars
NAPA #277-3038 ('78 MII V-8)
50's cars and pickups
NAPA #277-3060 ('84 Mustang 5.0)
Very Heavy Engines in 50's & 60'G pick ups -460,454, HEMI

Above assumes small block engines, go up one step for any big blocks."

I have a pair of the '84 Mustang 5.0 springs under my '55 with a 460 and the springs will need to be cut to bring the front end down to where the control arms are level. I haven't cut them yet because I'm waiting for them to settle a bit. Definitely some stout springs.

You might contact A1 Springs. I bought a pair of their springs some years ago to put under my 29 Ford with small block for $70 a pair (price has probably gone up by now). You tell them what you are putting them under and what engine you have and they calculate which springs you need. Worked out for me as the car rode great. I did cut 1 1/2 coils off to lower it some...
