For power, the TTI seem to work good for a shelf Abody-Bengine header but if you are ever going to compete in SS...you'll need a custom set. FWIW there was a company advertising a shelf header for this application on racing junk. I have no experience in the 'service access' that the TTI allow and when a custom set is made they definitely can be done in a way that saves time and grief along with making more HP.Will start prepping a '68 GTS for SS. Looking for headers that will fit the 440.
I have 1 7/8 on my Spool mount 440/727 in my 68 Dart. I think they fit well. I bought used so previous owner had to ding them near the torsion bar. I did a thread on how I changed my mini starter with them. I can't speak for the 2" ones only read they were tough.Have the 2" Tti on my 72 Duster with a 440. Really wanted the 1 7/8 but Tti says they don't fit.
what a quitterTwo, just helped a guy with a 440 and TTI 2" headers. They hit most of the steering.
I called TTI and they said they probably do! I made spacers to raise the motor. It helped some but not enough. The guy is now going the small block route.
Wasn't my call, but I didn't try to talk him into it, or out of it either... If his engine was mounted by engine plates I would have done something completely different. But he had the last say. Gene.what a quitter
to go to the trouble of fitting the 440 to then give up 'cos the headers need work to make them fit?
