Reply to "Passenger side head over heats"

If your dyno sheet shows 14.6 at 3500 then there is something drastically not right with that carb.

Look at both the idle air bleeds and high speed bleeds.

Simpler, borrow a carb from someone and see if the situation changes itself.

Not for nothing but how can it possibly be making 630 something hp when it is that lean? Try 150 to 200 until you start dialing some fuel into it?

Sounds like this guy gave you a fictitious
print out? Were you there when they did the runs?

With any kind of advance in that engine, say 32 to 34, at 14.6:1 you are going to put a hole through a piston?

Change carbs.


In my 2x4 Holley set up with two 1850 carbs the idle air bleeds were changed down to .021" to get the exhaust temps down.

They were so hot with .080" idle bleeds they burned the ceramic coating off of the headers.
