Hey guy's I finally found a set of inexpensive headers to fit my 351C powered 83 T-Bird. As most of you have been reading this past year I have steadfastly refused to spend $400-600 bucks on headers. Not because I wanted to be a jerk about it but because I have a family of six here and I couldn't justify the money. I have researched this and finally decided to buy a set of Dynomax from the people at Jeg's. They are for a 1970 mustang and have 1 3/4 full length tubes with a 3 1/2 inch collector. They say that they will not fit a C-6 transmission and powersteering but I bought them anyway. Only $99.00. Well, they wern't a perfect fit but they bolted up just fine. I had allready made a notch under the pass. side tunnel just under the A/C drain tube to fit the stock 70 Mach 1 mainifolds and it just so happened that this was needed for the number four tube to clear anyway so the pass. side was a perfect slide in fit. The drivers side fit was even better with the exception of the number five (front tube). It is about 3/4 of an inch to far to the outside to clear the steering shaft. It was so close that I took the header back off and bolted it onto a spare block and head, then I just relocated the tube in 1 inch at the point where it would have hit the steering shaft. I did this by heating the tube at two points about 12 to 15 inchs apart and using a porta power to push it in at the point that it needed when it was done the tube was not smashed and since it was held in place by the mock up head it was still in perfect head allignment. Didn't cost a dime to modify the headers and they clear the C-6 trans with no problems since I run an aftermarket shifter anyway. This may not be for everybody but you can't tell any difference from looking at the installation that is wasn't made for the Fox body. Only $99.00, I saved at least $300 that I can use for other things like groceries and house payments.
