Re: Iron Dukes??
I built one back when they first came out, They had a special block and forged 3.25 crank and the one I had had the S.D. cast iron head. Later on guys in comp adapted the splayed valve Chev head to the S.D. block. I know some poeple are using a Gaerte block in comp now. Bob Michael.

Re: Iron Dukes??
Alyn Armstrong's opel GT was (is?) powered by an iron duke with a billet head he made.
Leave the line at 10,000 and shift at 10,500! (unless that was his extremely dry humor, never can tell) |

Re: Iron Dukes??
I remember seeing one on a stand at a local speed shop and wondered why someone would build such a radical 4 banger...curious how many versions of the 'Iron Duke' there were, and which production cars they came in.

Re: Iron Dukes??
I am no expert (far from it!) but, I think that was the 4-cylinder engine that G.M. used for the first FWD X-cars, (Nova/Omaga/Ventura/Apollo) that were introduced in the early '80s.
It had the same bore-center spacing (4.4-inches) that the chevy small block (and, 4-and-6-cylinder Chevy II) engines had, so they probably used some of the same tooling to build it. The upside was that Chevy V8 heads used the same bore-center spacing and I'd imagine, could be adapted, by moving the head bolts around... But, Pontiac (remember THEM?) had a hi-po program for this little engine, and came up with a head that bolted on (aluminum) that was claimed to flow better than the Chevy stuff at the time. For a pushrod 4-cylinder, this thing was about as good as it gets, IMHO...

Re: Iron Dukes??
the late Bob Wollett ran iron dukes in both the old Kathy's Clown Firebird he got from Stover and his new olds he raced before retiring. I know his son Jason has everything still. I have not talked to him since Bob passed away to see what he is going to do with everything.

Re: Iron Dukes??
Jason still has the cars and wants to race them someday. He has NO plans on selling them.http://i256.photobucket.com/albums/h...scan0001-2.jpg
