I'm not an expert on stock car racing but don't pace cars run much slower than racing speeds?
With the right gearing a 273 should be able to hold up for at least the race i would think.
Yes they run slower than race speeds, but I’d guess a 273 would need some engine mods and maybe gearing changes to run a decent pace speed.
Does anybody know what typical pace speeds were back in the mid 60’s?
