OOPs 3369 for the convertible. Thought it was the heaviest 302. It's the heaviest gas engine offering of that model and year.

That puts the 302/260 Cougar engine at the bottom of GT/J close enough to move to GT/KA.

I think bracket racing what I have with a Holly 600 that would be legal on the 260 hp Cougar for this season and switching the pistons to flat tops over the Winter for GT next year is the best way to go. Carb specs for the 260 Cougar are 1563 1563 1250 1313 the Holly 80540-1 is a 600cfm carb with a throttle bore of 1563 and a venturi of 1229.

EDIT: The 68 Cougar 302 is 230 HP, but does have the Holley carb.That puts it at GT/MA with the heavy body weight of the convertible. The actual car, 68 coupe 302 is 2874. That's 495 lbs lighter than it's classification factor. Is that right? This is favorable, yes?
