I ran across a few "made" W-codes with faked tags. Frankly I wish I had bought this one, having enjoyed a ride in it.


...but throwing in the HM modified 68 427s. One being sent to Ford France for Henri Chemin and the other to Martin Birrane for racing. And no, I have no HM invoices for those, but talked with Lee and the genuine mechanic there about them.

At least just for the entertainment of some, not for the added pain of others:-).

I would love to see that Tunnelport ad but it will not open up for me for some reason, I only can view the thumbnail image.

I have heard that the 427 Tunnelports need to be stroked to 482ci or more to be "streetable."  Do you agree?

You would have to define streetable- I have a couple friends that drive 1800hp and 2500hp turbo cars on the street they could be considered Pro- Mod cars. So a standard 427 runs real well on the street the only thing that makes them unfriendly for street driving is the compression ratio requiring race gas, my car uses 112VP 90 DOLLARS for 5 gals Cry or a camshaft requiring you need to spool up the motor in the upper rpm range to make power. If you run average engine set up they will run forever with normal maintenance, after all they did power irrigation pumps for industrial use. Cheesy

Thanks!  I had heard that the Tunnelport 427 top end setup was not a good performer at lower rpm, and thus not the best choice for street use.  Would a low riser 427 top end setup actually make more power at lower rpm than the Tunnelport (assuming a non-stroked 427)?  I am curious because of how Ford seemed to be marketing the Tunnelport over the counter setup.

   Yes the low riser head made better bottom end torque than a tunnel port. The tunnel port was deigned as a Nascar head after the cammer was not accepted for use by Nascar. IIRC it was the result of work by Norm Fausten and Joe Eastman , highly talented Ford engine engineers. The novel port design was revolutionary back then but it is very obsolete in today's world. Aftermarket offerings are far superior.
