I looking at a 1990 f150. I have a few questions. Only because I've never owned this new of a gas truck.
1st. He claims to have gt40 heads on a 351..I'm not really sure if that's possible also he said he parked it about 3 weeks and it ran fine. Now it has a unburnt gas smell coming out of the exhaust and a tiny miss. Almost bearly a hiccup. But it's got tons of new proformance upgrades.

I told him I wanted to look into posible problems before bought it
any ideas anyone?
