hi fellow mustangers,

i took out the boss today. what should i say.....it was a blast :)

i hope to get an appointment at the registration office this week so i can get the inspection taken car of. a lot of red tape here in europe to get a car like that on the road...but it's worth the hastle.

thanks guys!! it's weird having 2 big bodies in the same color....but i really enjoy it though :)

 
Abudi,

The car looks great! All of your hard effort and work is now complete, time to get the paperwork done and start enjoying it. Do you plan to install the Boss 351 decals?

 
Abudi, I'm just making my way around the site and seen your thread, when I get time I'll read it all through. Just read the first couple of pages and the end couple of pages. Am looking forward to reading it all the way through. Great car!!
thanks mate. if you're ever in vienna let me know and will take the beast out for a spin :)

Will do, Abudi. Would love to hear those mechanical lifters.

 
hi folks,

it's been a while since i lasted posted on in this thread. here in austria you have to pass a historical car inspection in order to drive a veteran car on the roads. my inspection was a few weeks ago and i had to fix 2 things on the suspension but besides that the boss passed everything. i am proud to announce the i have the one and only 351 boss in austria :)

thanks folks!!

it's been a rough road for the boss so far but we're gettin' there.

this 351B is one bad *** beast. i was doing around 30mls/hrs and floored it and couldn't believe that i was having a hard time getting a grip on my tires!!! i have to switch the rear end. 3.91:1 is not drivable !!!

hi folks,

it's been a while since i posted something here. i am in the process of switching my 4 speed toploader to a t5 worldclass. here are a few pictures of the disassembly and of the partial reassemly. i'll be installing the t5 tomorrow so there will be more pictures of the installation.

the old overhauled 4 gang toploader



the stuff from modern driveline (transmission, shifter, spacer etc)







i removed the H pipe for better access







the bell housing without spacer





T5 worldclass 5 speed tranny





bell housing with the new spacer



ready for installation





more to come soon

Glad you checked back in with us. Looks like a great mod.
thanks!!

i'm still not sure if i should change the 3,91:1 to a 3,25:1 ratio. depending on how good the milage gets, i might do that as well.

thanks

You will not the like the performance side of the gear change. When I went to my TKO600 I went from a 3.91 to a 4.11 gear. Love it

 
maybe i'll stick with the original 3,91:1

i'll know more tomorrow and will post here as soon as i test drove it.

thanks

hi folks,

today was the day. a friend and i switched the toploader with the t5 worldclass and everything went as planed. the guys from modern driveline really came thru with their package. the only "real" adjustment were made on the bellhousing. after we put in the spacer the the tranny slipped right back into place. it was installed in 10 minutes :)

the drive shaft slipped in just like before and no shortening was needed.

i stuck in an old yoke into the tranny and put it into 5th gear. while slipping it into the engine i turned the yoke and the entire tranny literally slipped into place.



in position (without the crossmember)



(with the tranny mount and crossmember)



the original driveshaft :)



danke and fertig :)



it took konrad and i 2,5 hrs for the entire reassembly with the mandatory test drive :)

t5 with 3,91:1 rear axle and 225 60 r15 tires

if you were to turn it to 6000 rpm

1 gear: 62 km/h

2 gear: 94 km/h

before 120km/h mit dem 4 gang toploader 4000rpm!!

now with the t5 i'm turning 2500rpm at 120 km/h.

140 km/h cruising speed 3000 rpm.
