was thinking shackle how large do i need to go to get a good lift to clear the pulley so it would touch

these are the shackles that i have removed from the front

Need help asap as i need to tell the engineering company to make them tomorrow morning

2 inches of shackle lift is 1 inch of lift i think i was reading some where.

is the diff sitting on top of the leafs or are the leafs sitting on the diffs?

the pulley is very close almost touching maybe it is touching but i had wood blocks under the bump stops to rise the chassis so i could run my engine when it was wired up

Check the angle of shackles when it's at rest. The shackle should be at a right angle or slightly under with no load. if the angle between shackle and spring is less than 45 degrees then the springs need resetting to adjust for the extra load of the bigger motor.

If your axle is half way along the spring then any height increase will be half the increase in shackle length.

However having said all that, if your axle is hitting the crank pulley at rest, then increasing shackle length isn't going to help a hell of a lot because it will probably still hit when the springs are compressed.

You'll probably have more success lifting your engine mounts if SOA is out of the question

Sorry yorick, but id have to disagree with you there, if you want a nice ride, then you want the shackle angles around 45deg. Load carrying is good at 90deg, but uncomfortable.

But if the jeeps are set up for a 90 deg angle, then ignore me
