I could be wrong but the minor issue with the T3 manifold was that it restricted the airflow to cyl 1 and some air flow was a little different from left to right side of the motor due to the inlet location and air flow going over the top of the runners in a loop movement .It was a made for tick ford by Morrison motorsport , formerly in Lillydale Vic , now located in NZ , they did an excellent job on it and for street driven applications its hard to beat , of course a full race motor may not get enough airflow , a fellow in Tassie is building a pretty serious engine with one installed so only time will tell. Indeed a rerun would be excellent as any that appear for sale are very pricey indeed, the top section if simply reproduced would be great and a 302 w inlet and a 351c inlet would be popular for sure however on a cost per unit sold basis this probably would not make a good business decision .

Adding to my post above i have found out that according to Tony of Astro in the US that Mal Wood is an Oz agent for their A5 gear sets as well ,it seems he is more inclined to sell his Tremec product . I misspelled the name of the WA guys its Streebuilt and they are put several A5 gearboxes behind some pretty serious motors , a 347 turbo V8 was one and several other over performing motors so a mildly modded 351 should not challenge an A5 at all . Imo using the A5 with an alloy bell housing also has a serious weight advantage as opposed to a TKO or T56 or Toploader that can also improve the acceleration and braking performance of these heavy cars . As others noted th T5 also enters the cabin at pretty much the same location as a single rail / auto / top loader so your console also remains as per factory , neat and tidy ,for me thats essential in my XY .

For those that prefer the T5 option there is an alternative to blowing them up , Astro in th good Ole US of A make a complete gearset to suit the E series T5 that depending on the internals chosen can make them street driven Clevo proof or track ready non synchro too. There are guys doing mid 10s in Fox body Muzzies in the US running these Astro transmissions ,the only drawback that i can see is there can be a little gear noise but then the cars that have this seem to be stripped out , so a fully trimmed car should be pretty quiet t. The T5 or A5 as Astro call it also retains the T5 nice shift and fitted with a short shift kit like Steeda branded unit ($190 US$ ) you can have a pretty good unit , the ratios can also be selected for 1st and 5th . The fellas in WA called Streetbuild have done a few and they pretty happy with them so far.
