Swap questions for 351W in 70 mustang

Sorry guys! Lots of questions....

I am storing the original cleveland out of my car and I have a 351W with the edelbrock victor jr heads.

1. Right now I don't have any exhaust manifolds. I am trying to look around, but it doesn't look like anyone makes headers for this combination...

Anyone have some that work? I am also putting in an AOD, but I understand that is smaller than a C6. My car has power steering and all that jazz.

I am willing to hammer them, and maybe cut and modify them a little if that's what it takes...

2. Will the regular (non air gap) Performer Rpm fit under the shaker hood? Anyone tried it?

3. What is a good ignition setup to run? I do not want go back to the cleveland's points distributor. Is there an HEI setup with a gear for a roller cam?


Thanks!

dougs headers, 1 3/4 length, 1 3/4 primary try y's, I think they are d669y's, I have them on my 408w in my 67 vert, they are absolutely the best header I have ever used, I am running an AOD as well

If you can't find headers for a Windsor in a 70, you haven't even started looking. Everyone makes these. You sure the motor you're trying to swap has a roller cam? There are lots of drop in electronic distributors with roller gears that are no more complicated than a points distributor.(Pertronix, Crane, Mallory) The HEI units look retarded on a Ford. The distributor head is bigger than the carb.

Which probably explains why there have have been so few responses.

Yup! At least on a Chevy it's hidden at the back.

I suggest doing a search in this forum on "headers" and "ignition". Plenty of good info.

There are lots of headers for a 351w in a 1970. My only thought is don't the victor jr heads have raised exhaust ports? If so how much would that change the way a header will fit.

The raised ports shouldn't affect anything. I've got raised port Canfield heads on a 331 and my Tri-y's fit, actually better than they do with the stock Ford E7 heads. Canfields are raised by .400"

Some companies might list them as 351w headers for a 69... Are you looking for longtubes or shorties? What is your budget? If that windsor has a little more life than what came from the factory, an aod might not hold up if it is stock.

Sorry guys, I think my problem arose out of my searching for a 351W in a 70, when I should have just looked at 69. Looks like to get something with 1 3/4" primaries I have to spend about 700 bucks.

The Victor Jr. headers are raised port, but hopefully that doesn't change it too much...

Yes it is a roller cam, I assembled the motor. I have about 2k bucks in the AOD before converter...so it better hold up.

...Anyone tried to fit the Performer RPM under the shaker?

FPA is said to make some really good headers.
http://www.fordpowertrain.com/Headers.htm
They list the 1 3/4 primaries you were looking for. Not sure about the raised ports but it is worth giving them a call. Seeing that edelbrock and hooker are the same company, hooker should have something in their lineup too.

Accufab has a header at a decent price: http://www.accufabracing.com/exhaust.htm Call ole George and he can tell you if it will fit a OD tranny.

Also, look at the off the shelf Hooker stuff. They have long tubes that fit well on a 351w at an even cheaper price. Not sure if it is the Comp or Super Comp that fits best, but here is a Hooker part # that normally works: 6208s (65-70mustang). Doesn't mention if they will fit the OD automatic though so you may be on your own.

My hooker supercomps clear my c6 so I can't imagine an AOD would have any problems knowing there is that much space down there.
