is it the original engine ?, has it been repaired over its life ? have the heads been replaced at all ? you may be able to find out the age of the engine case from the engine number , its impossible to tell from here!!!!!!!!!!!!!!!lord chris said:it the 1500 engine in my 62 notch? so is it or isnt it :S
you should be using 4 star or a lead additive. But there are many who run their earlier engines on unleaded anyway because, after a lifetime of lead, there's a bit of resiliance built up and you're more likely to have a problem with something else than not running 4star.lord chris said:its the original engine. and i dont think the heads have been changed.
