Not that simple.. What do you have? Engine size/hp. Body style. Weight, Tire size etc.

Powerglide but would work better with 4.88 gear

T400 if you keep 4.56 and get more rear tire I realize these bodies are somewhat tire restricted with stock body. Back in the day I ran a 70 with BB in it. 10.9 tire was the most tire that would fit. Lots of traction issues.

4 link cost

Sub frame connectors, 6 pt roll bar rear frame rails 4 link kit narrowed rear end housing Axles ,spool rear gear, coil over shock kit rear brake kit to fit rear wheels/tires to fit narrowed rear end, wheels tubs and interior kit. This could cost 6-10K

A lot simpler to run a Glide and a bit more gear.

No body has said this yet and should have.Unless your deep into tooling and equip where your making your own frame rails/kit,the chances of you building a 4 link car cheaper than buying a 4 link roller are not very good.The question of a glide certainly directly involves the car's wt,final gear ratio,power band of the engine,rpm limits.BTW the wt includes the fact a 350/400's wt is heavier than a glide.The reciprocating wt of a glide is less than a 350/400's wt as well.It's because of that fact a glide is more of a reaction trans.But 40 yr old glide cases are not built to hold up against today's engine outputs.Because of that a aftermarket case is almost a given.I'm telling you that founded on 30 yrs or so of glide use in many different cars in Super Gas with a brake. And they aren't cheap.

At ~475 HP, I'd be looking at a TH350. Not that much heavier and closer gear splits to keep the engine in the powerband better than a PG. Allows a little less rear gear ratio. If you were to drive this on the street that can be a plus.

You could set up the rear end w/a 4-link and mini tub it. This will give you plenty of footprint for that power level.

To get an idea of what it takes to install a ready made kit, take a look here.

More general rearend info here.

The 68 Nova dont need 4 link and tubs at that HP level.

There are similar cars that run in the NMCA type races with stock suspension with Cal-Trac bars on drag radials that run into the 8 second zone in the 1/4 mile.

On radials the T-350 may work well with the low HP

Torque converter design would be very important

Im in the 3 speed crowd,especially with your lower HP and only 4.56 gears.When I put a glide in my 67 Camaro I also put 5.57 gears,with a similar low output engine and I used a 5,000 plus stall
