I've heard people with trucks with 292s talk about getting 10 mpg or less. I've always figured it was due to the low low gearing. Do you suppose a 292 would do much better with some good, high open road gears like something in the low 3s? It appears that I can get the 292 for a very low price. The owner says "whatever you think it's worth". He has checked the numbers and is sure it's a '66 292. I might do something that I've never done before...paint a Chevy engine something besides orange , or gray, like my '54 235. I think the original six in the Pontiac was green. Just thinking.
