^That truck isn't coming from the Factory.
I'm guessing that photo was taken right after they were modified & converted with 427cid.engines from another jobber offsite,like Dick Harrel,then shipped back to Fred in LaHarpe,is why they now have Cragars.
After visiting Freds old Dealership in LaHarpe about 25 years ago,I saw how small their lot really was.Helen told me they didn't have much room for holding a large amount of anything,so Fred would sometimes ship vehicles to another area briefly,before quickly finding buyers.
Even 50 1969 ZL-1 camaros.
