Depends on who you ask.
It will easily go over the 150 mark though.
Needless to say, it will go faster than any legal speed limit your likely to encounter on U.S. roads.
PS: At least one member swears his will hit 171

349.8 cid actually...
Bore = 4"
Stroke = 3.48"
8 Cylinders.
Cid = πr²Ln
Where
π(pi) ≈ 3.1416
r = radius (of the bore, which is 4"/2 or 2")
L = length of the stroke
n = number of cylinders.
So, Cid = 3.1416 x 2² x 3.48 x 8 ≈ 349.8 cid
As for top speed, I dunno. But! I had my '95 LT1/M6 Vette to 155mph in 5th

I have to agree with cuisinartvette.
Remember, back then they didn't have overdrive transmissions.
With a 4.11 rear that thing would red line before 140
RPO L72 (427/425hp) had a redline of 6500
So, that would put the max speed at redline in 4th gear approx. 127 mph.

The tire size is not exact, since they used a different measuring system back then. But that 205/75-15 is probably close enough.

I have, and I do. I've taken my 67 435 to about 120. In discussions I had with the original owner, he trapped the car at 125 in the 1/4 mile and had it to 155 on the highway. He said the steering was about gone at that point so he backed off.
As a note, the 67 L88 at LeMans hit over 170 on Mulsanne.
