your opinions on spitfire headers
On the spitfires - the drivers side was a pain to get fitted on my 66, the headers outlet on mine pointed directly at the torsion bar with little room to spare. We ended up piecing together some pie cut tubing and got the outlet turned away towards the gap between the tranny and the torsion bar. My car is a floor shifted automatic so I dont have alot of the stuff in the way that a manual or column shifted car might. If it was not designed to avoid a z bar or the column linkage then I am not sure why the outlet was aimed that way, they would have fit easier just having specified using the late model mini starter, and then redirecting the outlet in a different manner. Oh well. I have yet to install the passenger side, but I have to believe it will be better. Not so much crap in the way on that side. BTW you do need to yank the column to install the drivers side.
Having said all that - the TTI's sure are pretty, but also expensive and terribly complex to install, you have to rip apart half the front suspension from what I saw. If you have the motor out and wanted to install them then I would say why not !
In my case I already had the shorties when TTI released theirs and my front end was already together. The nice thing about the shorties is you dont have to rip the car apart to get them out if need be. Just the column which isnot so bad to do.
