Good reading, I do favour the 307 over the 305.  One small error . Did you notice ? 307 is a large journal crank not small journal.

Yes, there certainly never was a small journal 307.

And I'm sorry, I have never been a 307 fan. My mom bought one new in 72 and that thing was a pig. Oil burner from day one, never improved. Many others share the same experience.

I'm sorry if I stepped on toes saying this but this has been my 307 experience.

Carl, no question the 307 is a maligned engined BUT look at that test, a 37 year old 307 pulled 230 HP on the dyno before they started building it up. That is a pretty good testament of reliability. I never owned one so I have no experience at all with this engine, just seemed like a good write up given that there is one for the taking basically.

I know my mom's 307 felt slow to me even as a 16 year old with a 283 Acadian!

We were never happy that it went 1,000 miles on a quart of oil too. The 350's didn't have that reputation.

And yes, I know what you mean about the dyno test Ray. Nothing bad with that. I just don't feel money invested in a 307 is well spent money.

Well your point is valid, they were never intended to be a performance engine, primarily gave GM an engine to help them meet CAFE.

Amazing that the CAFE was already pushed that long ago. Time flies!

Also amazing (to me anyway) was the fact that with a 2.56 gear and a slightly leaned out carb, my 67 GP wagon with the 396 was as good on fuel as my mom's 72 Malibu 307.

I had a 307 in my 68 chevelle and went on a few trips to Kingston and back with it and had no problems with oil usage. I put a lot of miles on that engine but must confess I swaped in a 350 HP 327 and was mutch happier power wise and also fuel was better with the 327. Go figure.    I think when your the smallest engine in the stable, most would rather swap out for a larger engine then spend money on a smaller engine.

If any one is going to scrap one save the crank as is the same stroke as a 327 and will fit a 350 block to make one.
