Please guys. I ain't having any of the "swap in a 904" kind of crap, I've heard plenty.
I have an 85 D150 with a slant in n it. And it has a 727 behind the slant.
Yes I can tell a 904 from a 727. Been at it plenty long enough for that.
I'm about to swap in a fresh slant, slightly hot rodded, hoping to match the power of somewhere between what a stock for the mid 80s 318 would have had, and a stock for 1985 360 would have had, if the truck "would have come with" back in the day. V8s of that era were pretty dismal in power output for what they were. Of all brands. .
Anyway now that the application has been covered, from what the starter has sounded like when I have run it to date on the all original power train, I'm expecting to see a bad spot on the ring gear once I get the original engine out. Meaning that's the time to replace my torque converter anyway.
I also know that without pulling the trans and swapping a bunch of guts with an older 727, this trans is stuck being a Lock up version.
I know that stock they had a low stall and a high stall. How low was low, and how high was high?
I also remember from the last time I was into a torque converter application guide/catalog, that any converter that listed as fitting a slant was also listed as fitting a 727 behind a 318.
That said,. I'd like to have a little more stall, maybe a bit smaller OD converter between the new motor and my existing trans. What is available in a converter for a Lock up 727? Anything besides dead stock?
I was all ready to buy a B&M tork master until I discovered by the PK number that my particular unit is a lock up version. And that particular converter won't work with a lock up. From what I understand that tork master was rated slightly over stock.
For now, until I "prove it to myself"that this power train combo won't be enough for me and for this truck, I want to run with as much of what's already here as I can. Oh yeah in case someone wants to ask it has a 3.21 geared 8-1/4 rear which also stays, at least for now. And tires are 235/75 15s
