Thought it was time to put on my new Eddy 4v and 302- 2121 intake.
Stripped it down cleaned it up ready for the intake.....
Figure I would install guide pins and dry fit the intake.
Intake is to narrow!
Now I went through this before with the firing order.....

I wired it for 351 fire order, would not start.
wired it up as 302, fired up.
VIN says "G" (351)
My assumption is P.O. pulled original 351, put in a 302.
this would explain the 302 firing order.

Now I order a Eddy 2121 289-302 intake, Sucker don't fit, too narrow.
Called the speed shop I got it from, Says there is two types of 351 heads and he needs to know what I have.......
how to ID the heads for the right intake????
Thanks

 

Heads are not going to make any difference. The 302 heads and the 351w heads or basically the same heads with very minor differences.

Looks like you have a 351w with a 302 camshaft.

 

Amen. The 302 heads and 351W heads are interchangeable, except for some of the 302 heads had smaller head bolt holes. And the cam determines the firing order, so someone may have installed a 302 cam as they interchange.

I agree it's a 351 firing on a 302 cam, but the speed shop is telling me there are two kinds of 351 heads, that's the info he wants to get the "right intake"

 

I'm pretty sure all of the 351W heads were the same as far as dimensions. Go look at the aftermarket intake manufacturers web sites and see what they say. But Edelbrock says of the Performer RPM:

 

This is what a have.
6-bolt covers, horizontal T-stat, 4 Waterports.
Original intake casting DE-9425 "C"?
Casting on Head is "78" "WC" with a "P" under it, and "4D5"
Width in the valley is 7 1/4", bolt width (center to center) 9 1/4"

 

The block says "351 W". But the heads don't have #'s on the top that are decodable - as far as I'm aware. The #'s you would want are only visible from the bottom. BUT, you might be able to see it with a mirror. In the picture below it is the D7OE on this head, which is between push rod holes.

 

Just a note Ford did build later 302s with a 351 firing order I'm thinking mostly In Mustangs .Cams are interchangeable with 302 351 engines but you must use the right firing order for the right cam 302 firing order for 302 cam 351 for 351

 

late model mustang 302's had the HO/351 firing order, yes

 

All 351w's had the 351w(and some other engines used it too) firing order. 302's had a different firing order except the mustang HO 302's which had the 351w firing order. I don't know what the later Explorers with 302's had in them.
I had a 86 EFI 302 out of a Lincoln Mark VII and it had the regular 302 firing order, roller cam and all.

 

If you look in my first photo, third pushrod on the left from bottom, and bottom right, are those "rod seats?" and is it normal to be higher than the rest? shold I leave them alone or "tap" them down????

 

Those are the lifters and they are partially up on cam lobes. If you turn the engine with a socket on the crank pulley you will see them go up and down. But, if you marked the dizzy before you pulled it maybe you shouldn't turn the engine or it may be difficult to get it back in time.

 

OK thanks Gary, just noticed them like that, as soon as you said "lifters" ...Click" light bulb turned on. Stupid me.
New intake should be here by Monday, Today I got all new parking brake cables in, Bought two drum cables, Tensioner assy, cab-cable caus they were rusted solid.

Figured I will replace the rear cables cause they were the ones rusted, and I could return the rest if not needed.

Disconnected the rear cables and the front cable/foot pedal worked fine. Cool I can return the tensioner/equalizer and front cable.

Adjust the tensioner, bolt snaps. O.K. got the new tensioner, I can still return the front cable, put on the new tensioner, try my foot on the pedal, all works good then Snap, front cable goes. Good thing I had the front cable, Nothing to return now!

 

Lol! I could see that developing, kinda like slo mo. But at least you have it fixed.

On the dizzy, you did mark where it was pointing when you pulled it - right? I like to mark where the rotor is pointing on the adaptor, exactly, as well as where the base of the dizzy meets the block. That way I can get it back in time, plus or minus a couple of degrees, when I stab the dizzy back it. If you didn't mark both positions you can still get it back close, with some work, but not quite as closely as with both marks.

 

Got the original dizzy marked, funny the rotor ended up a 12:00 high noon the last time it "ran" As dizzy got pulled, it naturally rotated to about 11:00
I will take the new HEI dizzy, position Plug 1 where it belongs and set rotor to 10:00 install and see if it lands on 12:00 noon.
Whit a minute.... I got the new HEI Dizzy for a 302... Will it matter now the damn thing is actually 351 firing on 302 set-up?????
