Hi All,

I'm stoked to be part of this community! I've got some big plans for my 1978 Cutlass Supreme. It was the family car growing up and I remember going with my Mom and Dad to buy the car at the Kastner Oldsmobile dealer in Napa, CA back in 1978. The car has been through family trips to SoCal, camping, weddings, 3 proms and cruise nights when I was in High School. My Dad has kept her in great condition, but now it's time to put my flavor to it. It's pretty much stock right now with the "tiny block" 260 CID and has 140,000 original miles. I just replaced the Cat and muffler. A work in progress indeed!

Best of luck with the car! It's gotta be special since it's been in the family for so long.

Have fun!

Hi ZDOG78,

Welcome to TOC.


260 block has the same external dimensions as the 307, 330, 350, and 403. The only differences are the bore diameters.
