Caltrac Tuning Info LOOK HERE

I got a question cause I may be in the 2% range that make it difficult to work. I have a 70 Duster with a 440. I currently have fenderwell headers that limit my front tires to a 25" size. With the smaller front tire I have a hard time getting the 5" of front end travel and maintaining enough ground clearance. I pulled the front snubbers and can squeeze out 5" of travel, but it seems a little bit nose down and my front control arms are almost parallel to the ground. I have tried every setting on the rear shock and some pre-load. I made sure the Caltrac Bar was parallel to the ground.

I didn't know if someone had a similar setup and similar issues. With the 440 rebuilt, I hit about 1.48 60ft and low 10.40's in the 1/4. I think there is more in it though cause I ran another 440 Duster with almost identical setup and SS springs. He ran a 1.43 60ft and low 10.30's in the 1/4. I can get it to hook, but almost any adjustment made doesn't affect my 60ft. Tips/Tricks?
