440 BB headache
How bad does it hit the cover?
Which booster are you running.
You have only 2 or 3 options that I can think of.
1. Install a manual disc master cylinder and ditch the booster.
2. Move everything over like a 68 Hemi Dart.
3. If it is only the booster that is against the vave cover, you might be able to find a smaller (slimmer) booster.
If anybody knows of a good soultion, please chime in.
