I keep seeing articles of folks asking about bolting mod motors to old small block trannies.. in light of that I stumbled onto 1 pic that had a tranny of each side by side with dimensions..... several dimensions were very close, so of course this got my wheels spinning...I took some pics off the web of the SBF bellhousing with dimensions, and made a trip out to my local pick a part....got some of my own dimensions off a 4.6 from an f150...ignoring the location of the starter for a minute "got an idea for that issue" my readouts on a few of the upper bolts and dowels were all very close...worst was .19, most were .05 diff or so....of course not perfect environment to do this sitting under a truck, just wanted a rough idea if this is something for me to pursue further...at this point I think yes think this is gonna be my big winter project...I have more info /ideas just wanted to start a thread and see if any others might have finally solved this problem, or started to attempt this also....any way unless somebody can disprove the dimensions I am coming up with, this might be the 1st of a long thread....would love to hear from you guys for better or worse
<p>You have to worry more about the distance and angle of those holes to the center-line on the crankshaft.</p><p>If it was possible, people would be doing it.</p><p>The one thing I've heard of that works is using what I recall is an early '91 Crown Victoria 4.6 block that uses the SBF bellhousing. I guess Ford didn't want to come up with a new tranny casting at that point.</p><p> </p>

yes thats exactly what I havebeen measuring, I will try to clean up my sheet that I have things scrbbled on and post a pic of it....
Check out the dimensions of the 2 upper bolts and the dowels in comparison to a SBF....
For starters what's to stop a person from replacing the dowels with bolts...
Gained a little bit of slop in all the bolts turn the engine and transmission up on the end get proper axial alignment by rotating the crankshaft a few times snug the bolts up and see what happens and that's just a place to start in my opinion
Is there anyone out there that can confirm the measurements that I've come up with in the previous picture? That was the best I could do sitting underneath a pickup truck in the junkyard trying to eyeball with a digital caliper....
Sorry for the blurry pic, sun didn't help...what your looking at is a C6 bellhousing crudely sitting on the back of a 4.6 mod with 5 bolts loosely through the holes....it's tighter inside the bellhousing on the mod motor then it was on the windsor, but appears to have enough room...this is doable, not a direct simple bolt together, but certainly not impossibl
