WarriorJim 5pts Having purchased a new 1969 Z28 Camaro, I'm partial to the Z28 302 cu. in. engine. Mine was strong off the line and good at top end as well. If memory serves, Chevrolet used a 327 block with a 283 cam and went from there. My only complaint was the 7 miles per gallon but at 29 cents a gallon I didn't worry that much.
