I was wondering if anyone at the 20th got a look at the engine bay of the GM bumblebee Formula to see what engine it had. In the 87 Hotrod magazine article it had a Duel overhead cam Super Duty and 4 supertrap mufflers that you can see out the back, and would run low 13’s. But all the pics from the 20th I’ve seen it looks like a regular V6 exhaust, check out the pics. Just a little curious, any thoughts

Perhaps a design change since the article? Maybe the guy found a more efficient way of doing things, and went with a more conservative system...

Sweet looking Formula. I like the wing

If Im not mistaken thats not owned by anyone except GM, but maybe they just took it off because it wasnt gonna be running down the strip anymore

I had heard they had problems with the original motor. I have not been able to confirm this. The original motor was a still born GM race motor that I only ever saw used in this car. They listed part# in Hot Rod Mag but never released them? The engine was to be used in IMSA in the GTP light Fiero's, but they used the standard SD up till ther end.

I heard after the Super duty engine was taken out of this car GM put in the 2.8 V6 motor. I was at the 20th but I didn't see the engine bay open.

It was basically a stock 2.8 missing the intake snorkel and filter system. They put it in to make the car moveable under it's own power.

I think some of these engines did get made for race use. I found the following pictures of 2 of these engines that were for sale.

Cool I had heard something about valve train problems and never saw one in a car. I am glade they are out there. Do you know what they were in?

The DOHC Super Duty took a crap from what I understand. GM did install a 2.8 V-6 So now its just a normal Fiero with drag racing chassis parts on it. I think GM installed the 2.8 so they could have the car for ocassions such as the 20th.
