I haven’t tried it myself with Cleveland or cross stamped rockers, you can buy bolt on 1.7 rockers to suit the Windsor in either stud or pedestal.

Going to a 1.7 ratio rocker will give it slightly more cam lift as it is increasing the ratio from 1.6

The factory cam in the base AU 4.0 is about .444 lift with the 1.6 ratio rocker, by going to the 1.7 ratio will increase the cam lift to roughly .470

The E303 has a very nice choppy idle, very popular in the US, .498 lift and 220 degrees@.50

Yeah the factory springs aren’t much chop, but you would be fine running the E303, might get some valve float around 6k rpm.

The E303 is a good match for the GT40p heads and they run out of flow around .500 lift, not much point having a huge cam and restrictive heads.

From memory the 40p head flows about 200cfm at .500 lift.

I’d look at putting bigger valves in, at least 1.9 intake and 1.6 exhaust.

No not with a billet steel cam.

I used either an MSD or Mallory steel gear with my F303 cam.

The E303 which 220@50 and .498 lift is a great mild cam, has a chop to it and performs ok. Be ok with factory springs and rockers.

You can get this grind from most cam manufacturers.

You will have to run a steel dizzy gear with aftermarket roller cams.

Just depends what you want to do with it.

yeh but what one ? the b 303 ?

The factory cam is fairly small, good opportunity to throw in a lumper bump stick.

If you intend to run power steer and AC, I’d keep the front serpentine belt set up on it and use all the AU accessories.

I’d go for the Air Gap manifold too and slap a 600 on it. I’ve got a 650 dp on mine and it rips.

What is it going into?

Compare that to a 1970 302 Windsor rod and piston.

The EB is V belt from memory.

The gt40p heads could flow 200cfm from factory, best factory ford Windsor iron head produced.

Basically 9.0:1 Comp and 60-62cc cambers.

The first of the EB series Windsor’s had factory forged pistons.

Yeah if you do a cam you really need to watch PTV clearance, anything over about .520 lift is getting into dangerous territory. However I know someone with .544 with no issues in a roller 302w with stock P heads and pistons.

It has the 4 bars dude.

Good score, what did it set you back?

i dont really think it needs rebuilding,i saw the car b4 it came out,even there is a picture on here somewhere of it,usual story grandad let the kid take his mint ltd for a spin and he crashed it into a fence on the front qtr but the rest was mint,im even getting the headers and cats as i told them when taking it out 

If you go for a standard style pulley set up, you will have to consider the water pump as the efi motors run opposite rotation.

What accessories will you run?
