Re: 427 vs. 428 vs. 429
If it has cross bolts, and is a good block, grab it, then post pics of the motor mount bolt area, we'll tell you what you have.
If it doesnt have cross bolts, check the crankshaft casting number for 1U, 1B, 1UA, then its a 428 or 410, and a good crank alone is worth about 400 for reference
If it doesnt have cross bolts or a 1U,A,B crank, write down the crank number and the head casting number between the spark plugs and get back to us before you pay anything
As far as 68 427s, the literature did say they were out there, but its a wives tale, Kevin Marti disproveed the 68 427 a few times. Aside from DEALER installs, none made it down the assembly line other than the Cougars.
We argued this one to death on the FE forum for 12 yrs now, and its pretty apparent that the plans changed after the dealer brochures were printed, there werent any out there factory installed (again, other than the Cougar of course). As much as we'd all love to find the white whale hyd cam 427 Mustang, Fairlane or other, Ford didnt do it
