Were all 1969 x33 cars Z28's. My friend has a x33 he said it is a z28 that was ordered with a 307 4speed with 12 rear end. I have never heard of this I thought all z28's were 302

Rest assured, all X33 cars are Z28s and had only one drivetrain-302 4spd-12bolt rear. Generally the 12 bolts were 3.73 or 4.10. trans could be close or wide ratio. Look in the site under 1969 and it spells it all out. http://www.camaros.org/diffs69.shtml
If his 302 was .30 over, it would be a 307!

it would be .030 and at .060 over it would come up to 310.55 or 311 cu. .030 would only be 306 cu. .040=307 Sorry to get so precise there Buddy.

Maybe.. but it wasn't ordered from the factory that way.. :)
A 302 bored 0.030 is close to 307 ci, but it is NOT anything close to the same as a Chevy 307~ :)
PS. Grizzly bears and rabbits are both brown haired animals, but one doesn't confuse the two ..:)
Correct me if I'm wrong here but I thought the standard bore 302 was actually 301.74 which when bored .030 still made it legal for SCCA ruling of 5.0L. Maybe 5.0L is a little looser term than actual cubic inches...Joe
A V8 with 4.030 bore and 3 " stroke comes out to slightly above 306 ci. If I recall correctly, the 'best of the TA teams " (ie. Pennske) used special pistons that were around 0.020" over bored to get under the 305 max ci (at least that was what was reported).. :) I'm sure they did whatever they could get by with.. :)
Boy, I'm sorry I started THAT!

Sorry Buddy, No slam on you intended, but it was informative and all is good. Thank you for getting us thinking.
For sure. It's all good. That's how we learn....Thanks, Joe
All good! A little tongue in cheek!
