i know the thorny headers will not work with the toploader/ z bar setup. does anyone know if the mid length jba headers with the modified z bar setup will work. they list the headers for the 64.5-73 289,302,351 mustang butthat should be the same as the maverick correct. heres the link http://products.jbaheaders.com/assets/images/products/Z Bar/1650z.jpg http://www.jbaheaders.com/feature_pages/65-70mustangnew.asp
Those 1650s might work... If they fit a 65-66 Stang, they are likely to fit a Mav. Those engine bays are about as wide, however they are a hair longer. Therefore headers can hit the firewall if they sweep to far back. Looking at the 1650s, it doesn't seem to be the case. It's quite a bit of dough to experiment though. So Jamie told you straight up that the Thorleys won't work with a manual tranny?
Oh boy... I might have second thoughts after looking again. See how far the driver's side pipes sweep back behind the last exhaust port? That is probably going straight into our firewall. Edit: If it doesn't hit the firewall, that sweep could be good for missing the clutch linkage.
The 1653s don't sweep as much, not at all on the DS. They are meant for a 351w/4 spd, but may be okay for a 302. Again, it's alot of dough to experiment though.
that last one looks long and looks like it wont work with the z bar setup. i'm wanting to run shorties because the car is real low
