I recently changed intake gasket because of an anti freeze leak near the dist.I also changed the fuel pump block off (new 1,been elec. pump since I bought it)and noticed it smelled like gas.I pull the dipstick and I am pretty sure I can smell gas in the oil.What steps should I take to trouble shoot?I'm thinking a head gasket.Thanks for any input ahead of time...Pat
I haven't started her up since,but I did change carbs and ran it once in the garage after.It was runnin rich,I'm no motor head,but what you're tellin me could be the problem.Cam info suggests a 850 cfm which I have,not sure on jet size...what max. fuel pressure should I be seeing?(holley carb)
It's been awhile but I think the fuel PSI should be around 6-7 Lbs. Somebody will verify I'm sure. If you do have gas in the oil I'd change it. Bad for bearings and a little dangerous if there is enough gas in the crankcase.
If you have been running the engine in the garage a lot without really getting it up to operating temperature, it is pretty common to smell some fuel in the oil. Really obvious when you run Cam2 or other leaded racing fuels.
Also, like the others have said, if it is running real rich it will definitely get that way.
The head gaskets have no bearing on this at all.
If you are not going to drive it, dont start it

Bill,I have run it a hand full of times with out letting it get to temps when I got it home.I had no fuel press. in the begining and found that the fuel filter was clogged(looked like someone had took a crap in it)and also the return line from the reg. was way to small according to manufacturer so i got that square to.It's my first hot rod(1st car period,always drove trucks,work trucks)and does not have to be run at all,atleast till I get her square.My fuel press. is set at 6 psi.I'm thinking I need a carb adj. along with allowing the motor to reach operating temps?It's a pump gas motor.Not verified yet but it's supposed to be a 10/1 comp.Thanks for any any and all advise.
