My (newish) 81 olds cutlass

Properly tuned, there's no reason why that 455 shouldn't get 12-15 mpg.

Maybe I should buy that motor off of you and I can stuff it in my wagon... 😀

if you're thinking of buying the motor for a good price you should be telling him he'll get 5-6 mpg..... :wink:


that engine must have massive torque....

lol, What was I thinking?! I guess the cat's out of the bag now...

455's make for good fun in a g-body.
