QuestionQUESTION: I recently recovered my '73 Mustang after 10 years of storage while I was serving over seas. I dropped the tank and flushed it and got it back on the road. The drivetrain is strong and rebuilt (351C 2V, 375hp). I have been driving it without issue but this morning going to work it started sputtering as if starving for fuel. I checked the inline filter and it had quite a bit of residue. It is running but it won't accept a prompt of the throttle. When I get on it, it still sputters out. Can bad fuel or residual crap in the lines cause spark plugs to foul out? I just need to get the thing back on the road. Any guidance will help.
Thanks,

ANSWER: In short, yes. Filters are not 100% and a lot gets passed.
If you actually did a good job on the tank, you may have a few filters to change to get clean. You may consider some hoses ran to a larger filter temporarily.

QUESTION: So far it is working out but I am replacing the carb for good measure. I replaced the plugs and it cleared up until I drove it. I think the carb may have some issues with the needles being clogged.
The next question I have is particular to the 73 Mustang 351C 2V. I bought headers for it and found that the stock motor mounts restict about 3/4" for mounting. I need about 1/2" for clearance. Ever hear of anything like this or should I look at other then Headman headers? I may end up buying new motor mounts and modifying them to fit to gain the extra 15-20hp. Any tips?

AnswerHeaders at best, unless you really drop some big bucks, always seem to need a little modifying. See if you can heat the pipes and get the clearance. Changing th motor mount is another option. I have had to put front motor pins on once raising it about 4".
