I have to disagree with Pat C (big surprise, huh?)
Elkys have been run in Stock, as cars, since 1959.
Same with the Chevelle versions (also in SS , where pickups aren't allowed)
The issue here is the 78-87 version with the unique 117 " wheel base.
Yes, it's in the truck brochure, but it's also listed in the car section of the NHRA guide.
I would bet some of the earlier ones were shown in the truck brochures too.
Anyway, they have been allowing the .430 cam for a while . If it's a f/u , they own it now.
I would have said..leave it alone now,...like the 283 459 intake, the 6X Pontiac cc's, the 400 SBC's
Don't even know where to start on the FE FFFFords...
