Rebuilt the 289 and swapped my C-4 for a '84 T-5 in my 1967 mustang and I've run into some problems. For some reason my engine sits too high that the fan comes less than half an inch from the top radiator hose. I don't understand how this happened since I compared the old motor mounts with the new ones and they looked exactly the same. Even tried buying another set with the same results. Jacked up the tranny to where it's top is touching the underside of the car and the fan's still really close to the hose.
Anyhow I decided that I'll cut out the inch of rubber between the motor mounts and bolt it together. This should give me the clearance I need but would create a solid mount. How bad will this be?
