I retro-fit a 3500 top end onto a 3.4L rwd block in an 88 Firebird. I have the timing tuned what I think is fairly well, but I'd like to compare it to the 3500v6 factory settings as a sanity check. A screen shot of a factory timing table from any car with a 3500 V6 is all I'm asking to see. Actually, a late model 3400 table would satisfy too. Your help is appreciated. Thank you!
