has this been done yet? i have a friend who will give us the clutch pedal assy. out of another mid 70's truck and i already have a bell. the current c-5 is on its last leg and i thought a t-5 would be a great swap giving us more enjoyment and lower first gear for the truck as well as overdrive. other plans include stroking the 302 to 347. has anybody here done this swap into a truck like this? we still need the trans, the flywheel and clutch/plate. will probably have to have driveshaft length addressed as well as the fact that the trans crossmember might have to be modified. im really not afraid of modifying things to an extent unless this becomes impractical.(like where is the shifter gonna end up?) im also not sure of the torque rating of the factory t-5 (300 ft lbs.?)but if push comes to shove we can get the tko. the truck will not be raced but will probably be goosed occaisionally on radials. any info or tips on doing this swap will be helpful.------------------

Chip,A T-5 and truck is an oxymoron. (Contradiction of terms) Like 'military inteligence' or 'airline food'. It might work if it's just a street truck and doesn't have to work for a living.  SteveW

I put a late model F-150 5-speed in my 67 Shortbox. It's a lot bigger tranny than a T-5. It was used in F-150s and 250s with 4.9, 5.0 and 5.8 engines. I wrote an article on how I did it. It should work on your truck.Kevin ------------------

Even if you have a ready supply of FREE T5's you still have to do the labor to change them every week.A 347 stroker for a mid-70's F150 is equally silly... those trucks are common with big blocks and even a 351W fits in place of the 302 and will be more durable.

tom, it isnt so silly under certain circumstances. like 1. having to buy all the accessories and brackets that bolt on the 351w or bb, 2. changing the front end to handle the added weight 3. the fact that all the bolt on parts like intake and headers you already have on your current 302. by the time you add it up, the stroker price is a wash and you havent made yourself a lot of extra work. a 347 is just as good as a 351w cube for cube and is a tad lighter. svt, what kind of gears and how comparable is the truck trans you describe to a t-5? usually a "truck trans" will have an extremely low first gear. we want it to shift with a little performance and be fun to drive. steve, this truck isnt much more than a toy. it aint no farm truck, its more like a show truck. the paint/interior and stereo were completed this year. something that looks this good should burn rubber. we dont wanna race it, we just want a little kick in the pants when we are on the street. i was thinking the low geaars in the t-5 and the extra stroke would give us a little tire smoke and make pappy smile without breaking the bank or trying to compete with john force.------------------

The T5 has better ratios, but it's moot if those ratios become 0 to 1 when stuff breaks. A Toploader would be a better bet.The added weight of the 351W is no biggie, it is simply a stronger engine to start with, can be built cheaply and fits in place of a 302 with minor changes. It isn't hard to sell the 302 intake ,distributor and whatever else doesn't fit. Brackets shouldn't be a big issue, depending which you already have some fit without changes. The swap to a 390 or a 460 is more involved but leaves a lot more potential and uses factory parts.

CHIPSBAD67,
I installed a M5R2 out of an 88 F-150 into my 67 F100. I also used the hydraulic clutch setup by modifying my stock clutch pedal assembly and mounting the clutch master cylinder on the firewall. It works great! If I remember right the ratios are:
first 3.75
second 2.42
third 1.43
fourth 1.00
fifth .75I've been driving with it for almost two years. The guts are WAY bigger than T-5 stuff. It shifts well and the overdrive is nice with the 4.11s I have. I wrote an article about the install if you're interested. Kevin ------------------

yes, im interested in the article. that trans doesnt have like a "bulldog" first gear does it. we really want the thing to feel like a passenger car trans, i havent driven any late model ford trucks with sticks. we arent talking a stick with a 3 foot throw are we? what is your cruise rpm at 60 with the 4.11's? does it smoke them good and move out with the 85 5.0 motor? heck we could go with a 306 and spend the stroker cash on heads and gears. i could get a toploader i guess but really want the overdrive so a hotter plant and deeper gears wont kill our wallet at the pump.------------------

Chip,The '77-'78 Ford f-100 and f-150s used a toploader tranny with a 4th gear overdrive. That's the tranny we had in Melissa's '66 before the t-5 swap. 1-2-3 were normal and 4th was o.d. They are cheap and perfect for the truck application. In fact Melissa's best 1/4 mile times were with the truck toploader (12.62), she was a little slower with the t-5 due to the extra shift.(12.78)  Followed by 12.002 with the c-4. SteveW

Chip,I used a Hurst shifter but I had to make a couple rods and a bracket if I remember correctly for a normal H patern. My Dad used the tranny in his Granada 20+ years ago, and my older bro was a Ford mechanic at the time. He got the tranny because it had a leak in the casting and was warrantied. It sat in G'pa's basement for 20 years before his grand daughter's '66 came along. SteveW

Steve, I seem to remember a toploader 4spd OD being in some of the Granadas. Is this the same tranny?

What about durability and shift quality? David Key talks like they are junk. I was thinking about trying one in a '67 Cougar one day.------------------

They shift like any other toploader, they just have 3 speed 1-2-3 ratios and have a smaller and weaker 4th gear since it's o.d.We ran one with 4.1 rear gear and it went thru the traps at 112mph in 3rd gear. The 4th o.d. gear was just for cruising. David Kee is probably tired of having them returned as cores. But they are cheap and will work well for Chip's truck application. SteveW
