Trust me, the Olds 350 is just as reliable, it not more when abused. We had a 75 Cutlass that my ex BIL ditch drove at retarded speeds. He just plain bagged that car and had a pile of miles when my Sister got it. Yes it had a slight knock at the end but had well over 300,000 km. That car went to the wrecker's, he sold and someone drove it another 5 years. Remember it actually had enough power to hurt itself but had a solid bottom end, pre 77, unlike the 307. Although I had a 307 last 450,000 km. I could have put a timing chain in and went another couple of hundred thousand miles. Still decent power and minor oil usuage.
