Can anyone add more to the story that is mentioned on page 68 item 04? Talks about Cosworth aftermarket DOHC heads for the Iron Duke four banger and the Pontiac/Cosworth hybrid head used in Fiero GTP race car.
If I am not mistaken these were the heads that were used on the Fiero's driven in the GTO and GTU classes when Joe Huffaker was sponsored by Dole (pineapple). I once saw a complete engine for sale at the Pomona swap meet and I considered purchasing it for my Fiero Indy but those engines were not practical for street driven cars. I have some information on the engine packed away somewhere so if you are interested I can dig in to it a bit more.
Thanks Harold for the offer but no need to. I hope that a little more light could be shed on this story. They said the Fiero was raced in the Canal Light series. And you mentioned Pomona, I use to go out there in the 80s and 90s, what a swap meet. You could buy anything from a Model A to a dragster frame and it was hard see everything in one day.
I have to correct myself. The Dole sponsored Fiero"s were powered by the Super Duty 2.5/2.7 liter four cylinder engines that were built by Vanderley Engineering. They had the Super Duty heads that were heavily modified but still retained the two valve cam in block design. The Spice used the same design but they experimented with the Pontiac/Cosworth heads and these were run in the Camel Lights Entech Fiero's. I do not have a lot of information on them but I am sure an internet search would be useful.
