I recently replaced the computer carb and intake on my sons 1985 transam that we had swaped a 305 for a 350 on. It ran great for about 1 week, but now when you rev up to 3k or above and let off the whole dash rattles. I can't seem to fiqure out where it is coming from. Any help would be greatly appreicated.

You may have a broken motor mount. Pop the hood and put the car in gear and rev the engine a little while holding the brake down and see if the motor tilts. It could be the engine tilting and the Dist is hitting the firewall
