Timing for a 307 or 350?
Above timing gear: 6509GM 5.0L G
The 307 was made from 1980 to 1990. The 7A heads were used in 1986-1990, so that narrows it down if the heads are original to the block. So I have a 307 based on the numbers on timing gear housing. My step dads friend owns a machine shop and supposedly bored it to make it a 350. So my question is what do I do about timing? Do I time it like if it was a regular Olds 307 or a 350?
