Re: Made an "un-popular" decision with my 307!
An engine builder told me the 307's got a bad rep because of the heads. Big chamber and low compression. Set of 'better' heads wakes them right up. The stock 307 short block is fine. It's still a small block Chevy.
At one time a cheap upgrade for the 170hp 2bbl 283 from the early 60's was also a set of used 305 heads (smaller chamber). Lots of passengers in my bubbletop thought it had a hot 350 until I popped the hood and showed them the 283.
Rock the 307!
