I would add Gear Vendors for one simple reason. I don't think MYSELF would change an original part of my car, just making upgrades. Gear Vendor is an upgrade of the original part, is an ADD ON section on my original tranny.
Otherwise, I think there is not 727 replacements with OD for BBs... or yes ?
But that's me
anyway, I can't afford it LOL
All the overdrive options discussed in this thread are able to be used with a big block.

What about the 200r4? Same ratio as the 904 w/low gear set and a nice .67 od. Can handle a good amount of power when built right. And no tunnel mods, just need to redo the cross member.
Yes, the GM 200-4R or the 700-R4 can be used. The 700 has the lower 3.00 first gear and the 200 has a 2.75 I think. Both are still lower than any stock 727. Either one can be built to handle a good amount of power and both are small enough to not require any crossmember or floor pan mods. You will still need to fab your own trans mount however. I think the only other real issue with those transmissions is you will need an aftermarket shifter. Their shift pattern is is PRND321 where the gear vendors and 500/518 have an electronically activated overdrive gear and will mate up to your stock shifter.

So the GV needs NO fabrication to fit? You can't tell me the GV will fit with no mods to the floor pan, it is much fatter than a driveshaft. Patrick is right on about the my " ALMOST useless extra gear" comment so I won't explain it again. The GM tranny does not just "bolt right in". How you gonna bolt in your starter? How you gonna hook up the kick-down cable to your carb? How you gonna bolt it to your mount? How you gonna bolt it to your drive shaft? I doubt it will turn out the exact same length, gonna have to shorten or lengthen the drive shaft, what about u-joints? Can you get one that adapts to a mopar drive shaft with a GM spline? I am not saying the GM trans won't work, it is gonna take a adapter plate, new converter and a whole lot more little things to figure out for a tranny that is no better than an A-500. BTW the shifter is of little concern, it just won't sho the extra position on the indicator but it will still work with a little creativity. If you go with a generic trans don't waste time with the 200 go straight to the 700R4, the 2004R needs lots of mods to handle any serious power and FYI the 200metric and 200C are 3 speeds.

I installed a G.V. unit in a 67 B body about 5 years ago and all that was needed was a slight amount of about the size of a Quarter.to the trans tunnel in one spot ..... The entire installation took about 6 hours including multiple beer breaks. If anyone considers that fabrication they probably spend to much time fabricating Doobies ! As far as a reduction of 700 rpm being useless??? There,s pro,s and Con,s to everything & It,s nice to have choices . some engine/gear combos might not need such a steep o.d. ratio . If i had a small block like the o.p. i would have went with a 500/518 instead.

Wilcap makes an adapter for this app.. I will use a floor shifter any so that will be taken care of. And yes you will need to make a trans mount, but how hard can that be, the 518 you need to do this also.

Fab work is definitely needed for the chevy transmission, along with an adapter such as the wilcap plate mentioned. However if a person has a car in which a 500/518 won't fit without modding the crossmember, and if said person is dead set against that, doing a bit of extra work to get the chevy transmission to work would more likely to be worth it to them than it would be to you or me. I would sooner just mod the crossmember if it really needed it, because none of my cars are worth much anyway, I'm not scared of modding and it's not visible after.
You say the 200-4R is the weaker one, others online say the 700-R4 is the weaker one. I don't know who is right, I've heard claims both ways. I don't really care because I'm not in the market for either of those transmissions anyway. I know both of them will need more upgrades dumped into them to holdup behind a big block, where a 518 with a race rebuild kit and that transgo shift kit will do the job. To run the GM trans, at a minimum you will need a new driveshaft, trans adapter, fab trans mount and an aftermarket kickdown cable. Not sure what speedo cable will mate that trans up to your stock speedometer but I'm sure there's one. The point is it can be done with a reasonable amount of work.

All these items can be done, even the speedo cable you can get. So, it is up to the owner as to which way to go. I would use the reverse manual vb on either tranny, if it were me. I like to shift gears without the clutch. Also, all these items you would need for the 518, except the adapter.

from what i understand the 200 you only have to mod the bolt in part of the cross member. the 518 you have to cut the hell out of the upper ( welded to the floor) part of the cross member. the 200 would be a lot easier swap then the 518 in my opinion.
Again, it depends on the vehicle. The OP was asking about a 72 charger. A 518 will fit in an e-body or 71+ b-body without having to chop the torsion bar crossmember.
One other thing to consider, last time I checked, the JW ultra bell to bolt a 518 to a BB was around $250 cheaper than that wilcap adapter, not to mention probably having to buy a special aftermarket flex plate to run the chevy torq converter. I know they also make an ultra bell to mate a BB to a chevy th350/400 trans but not sure if that would also work on a 200-4r or 700r4

Thanks for all the input. I am still studying. I can't ever remember taking more time to decide on something on a build than this topic.

I'm putting a 518 behind the TT440 in my 72 Imperial. The Ultra Bell is already in my garage.
