Z-Dreamer Posted May 23, 2005 Share Posted May 23, 2005 While surfing some mustang racer sites, two shops were mentioned frequently as being quality vendors for G-force and Tremmec transmissions. The first is a company called Astro Performance Warehouse. Their URL is www.astroperformance.com/ The other is a company out of Florida called Promotion Performance Powertrain. I've been unable to find a URL for them sorry. But I do have a contact name and phone number. Contact Walt Leaman at 954-771-5575. Yes there are alternatives to 'BUBBA' at G-force.

HB280ZT Posted May 23, 2005 Share Posted May 23, 2005 After looking at the Astro Performance Warehouse website I saw the Tremec T-56 6 Speed Part# 1386-000-012 and started thinking, hum what if. Would this tranny work with the bellhousing from the 83 T5???? Boy would a 6 speed be really nice to have in my 77 280Z. Lots of thinking to do about this one!! Will have to contact Astro and see what they think, hum hum!!! HB280ZT Quote Link to comment Share on other sites More sharing options...
HB280ZT Posted May 23, 2005 Share Posted May 23, 2005 Oops!! I should never post before my first cup of caffeine kicks in. Now that I think about it the T-56 that they are talking about probably just has a custom bell housing to work with the Ford 5.0L. Oh well, maybe someday someone will make a bell housing so that we can put a T-56 or some other 6-speed into our Z's HB280ZT Quote Link to comment Share on other sites More sharing options...
510six Posted May 23, 2005 Share Posted May 23, 2005 http://pg.photos.yahoo.com/ph/sss510six/detail?.dir=15c7&.dnm=ddb7.jpg&.src=ph You mean kinda like this one?It`s an expensive upgrade,the only reason I went this route was I wanted a manual transmission and 500+ HP motor.I would stick with a upgraded T5 or a KA upgrade depending on the HP level.

HB280ZT Posted May 23, 2005 Share Posted May 23, 2005 510SIX, Thanks for the info, by the way nice setup. I was looking at the 6-speed because of the extra over-drive. Right now I spend most of my time on the road but I also race it on the weekends (autocross) so I need the extra gear. My current setup has a 3.90 rear gear with an 82 5-speed so I have a good over drive but I am still running about 3000 rpms as I drive so having an extra over-drive lower then .74 would be great.
