5300 RPM in 4th gear with a 3.08 and 27.4" rear tires would be 140.3 MPH.
A auto would be slightly slower due to converter slippage.
Now comes all the variables.
Do you have the torque to get to 5300 in 4th?
Flat road or going down hill!
Tail or head wind?
OD tranny, what ratio?
No magical formula, lots of "what if's"

Making a lot of assumptions (torque curve, body, transmission, tires) I'd say ~125, taking just over a mile to reach TV with a stick and about 1.3 miles with an auto. With only 200HP, aero is a big issue. With more details, I can run a more accurate sim on the C3 in question...

the top speed of the 1984 C4 vette with about 200hp is listed at 140mph with the 4+3. I would say that is ambitious since i had a 1984 and getting it to 140 would have been a miracle, although i had the automatic. Practical limit in my set up was about 125 or so, and after that it was torque limited. because of a variety of issues, you can expect a bit less in the C3. I would say 115 to 120, maybe. 125 is possible under the right conditions and with enough road (miles). the l48 will be torque limited. I now have the opposite problem since my l48 is no more and i have a zz4. now i am rpm limited as the vette will turn 150, but is well beyond the redline there. need an overdrive.
