Hi all. I am helping my dad out on his 33 Ford roadster with a SBC 350 in it. The engine is a bit of a mystery, It is a Hecho En Mexico block, with 041 iron heads. Stock or RV cam, sounds very mild. Not sure if it has flat tops or not. It had an Edelbrock dual plane with a Quickfuel 650 DP. Nothing else is really known, It came in the car and it runs. The distributor is a OEM Hei. We Set the Total Mechanical timing to 34 degrees at 3000 rpm with the Vac Adv. unplugged. The timing is all in at 2400 rpm. The timing is sitting at 19 degrees at idle with the vac advance off and goes up to 35 with it on. As far as I know, it should be 34 all in Mech, and around 10-12 at idle. So some how I'm idling 7-9 degrees too far advanced. The car runs OK like this, dosent seem to knock or anything, but im worried its too much timing.
