I'm not sure what you mean by "new" gas, but if you mean unleaded it depends. If your 307 is original and untouched or has been rebuilt but did NOT receive hardened valve seats when the heads were done it will NOT like unleaded gas. Older engines (pre-1971 in GM terms) require leaded fuel or at the very least lead additive or lead substitute to continue to run properly. Running a lead-required engine on unleaded will not immediately damage the engine, but it will destroy the heads and valves over time.

are you talking about "reformulated" gas?? with MTBE in it? it will not really hurt anything it just burnes LESS clean and getts LESS MPG and is POISONING the environment, wont' be long before they get rid of it, especially with it being a gov. mandate to use it and only 1 company has the pattent on it.....

As far as leaded vs. unleaded, I have read that cars that require leaded gas to lube the valves don't really need a lot of lead. I have heard that putting lead additive in a tank of gas every 5 to 10 tanks (if I remember correctly) will provide sufficient lead for any engine.

If your talking about the reformulated stuff like CHEV-HELL is talking about, if it tears your engine up, it will tear up a lot of others too. Save your gas receipts, maybe you can get in on a class-action suit
