Does anyone know what the b-303 cam from the 86 cars should have written on it?
Looks like my cam has 11EB-3 on it.

The 86 cars didn't come with a "B" cam. Oh and don't install one without first checking piston to valve clearence. The 86 engine has no valve reliefs in the pistons and is hit or miss with increased duration camshafts.

Don't take this in a bad way I love my 86!

I know I have read that post before. I have a picture of a B-303 somewhere let me see if I can find it.

Some people have claimed they got them and some did not. I question whether my 85 got one as it idles pretty smoothly.

This is ONLY for coupes! Verts were not supposed to get one!

How to tell:-

Start car with cold engine, as in 1st start of the day. Leave tranny in neutral, foot off gas. Wait. Wait. Anywhere between 5 minutes and say 8 minutes. IF she has the B303 she'll start to get "lumpy" and then "jumpy" and erratic, as you watch the Tachometer surge up & down. Eventually the surging will take control (around 8 minutes) and the car will ultimately stall on you. On immediate re-start she have high RPMS.

IF she follows this text-book style, you have the B-303 Cam in her.

MOST 1985 did not. A few seem to. Absolutely NO convertibles. (Well, at least on delivery day to owner #1)

Well the only problem with that way of testing is the motor is out of the car. I cannot remember how it reacted when in the car since it has been out for about a year now. But if I remember correctly, that sounds real familiar., Not sure of the stalling though, I never just let it idle after starting. I do remember though that it loped through parking lots at real slow speed though. And how do I remeber that, the wife always yelled at me cause she though I was bouncing the car on purpose.
Hopefully, someone can come up with a i.d. number for me.
Thanks,
Mike

Since it is still in the Ford Catalog, try measuring it or call Ford Tech Support and ask them.

Well, looking at my F cam here, it has F 303 stamped on the rear of it. Maybe the others followed suit? You'd have to remove it though to find out.

I don't think any of the cams were B-303's, more than likely they were a version simular to a B-302, which had different timing events to work with a speed density system. A B-303 will not run right at all with speed density, the lobe seperation plays havick with the map sensor.
