Offenhauser 360 and Hooker Header

Post #1 by CoupeBoy » Mon Feb 15, 2016 4:50 pm

Last Friday I had the opportunity to buy a used intake and header set.

The guy I bought it from said that they would not work together, he tried and couldn't make it work.
He did not specify why though.

My best guess is that the exhaust runner directly behind the carb heat pad might contact the intake.
Image

This bolt looks like it will be a pain to install
Image

One weird thing is this plug in the intake manifold.
Image
It is just a piece of plastic siliconed into place.

I'm still not sure what I'm going to do with it..
This comes to mind.

That's an old intake. :D I had a set of those Hooker Super Comp headers.

It's not uncommon for some clearancing to be needed to make some headers and intakes fit with each other. This is the reason you see quite a few modified intakes for sale on ebay.

That plastic pin is just an alignment dowel pin to help assemble everything on the engine.


Those headers will take a lot of mods to fit in a car!!!

What kind of transmission do you need?

The crew cab currently has a 400/c6/married 205. If I wanted to put in a 300. I'd need a SBF compatible transmission that will bolt up to a np205.

I'd be happy to find a c4 or c6. But if I could find an overdrive AOD or E4od, I'd be thrilled.

I've got a C6 but it wouldn't do you much good. It's in my 89 E350 behind a 351W ( 2wd ) . It would need the output shaft and tailhousing swapped out. All my NP205's have NP435's in front of them.


You couldn't pay me to swap in an AOD or E4OD into one of my projects!! :D I like the NP435 4spds. The AOD just isn't strong enough for a heavy vehicle without some beefing up. And the E4OD is computer controlled and not the most reliable. I've got an E4OD in my 96 E250. :bang: The C6 will be the easiest to find. Find just about any 80-96 4x4 full size truck or Bronco with a 300/302 or 351W and you should be able to find the C6. The only 4x4 Aod's I've ever seen were in 85-87 Fullsize Bronco's with 5.0L's.

If I had pedals and could find a divorced transfer case I could entertain swapping in the zf5 speed I have in storage.

Actually finding a divorced transfer case would make a lot of things easier.

What year is your crew cab? Pedals shouldn't be too hard to find. They have to be easier then finding them for a 75-91 Econoline!! :lol:

The divorced NP205's pop up for sale in my area about every 6 months. The downside is they are more expensive then the married ones. I can usually find a married NP205 for $50-$100. The divorced ones are usually $200-$400. :roll: If you want me to watch for one just let me know. :thumbup:

The crew cab is a 1975

I'm really on the fence regarding a divorced transfer case.
Married is so easy. And it's already setup with the correct driveshafts.

Although if I ran a 203/205 doubler that might make the rear driveshaft short enough to be 1pc. And it would alleviate some of the front driveline angles.

Right now I'm swapping in a 38gallon tank to replace the original 19gallon at the rear between the frame rails; and I'm also swapping out the broken rear leaf springs for a set of 2009 f250 leaves and performing a shackle flip.

Old trucks. Good fun.

Nice year on the truck!! :D

If you need any parts for the 75 I know a couple places that may have them. The one has lots of old Ford stuff but his prices aren't what I'd call dirt cheap. The other place specializes in 65-79 Ford trucks. But he's hit or miss on the prices. Some parts cheap others not so much.

I know where there's a few NP203's too if you need one. :D I'm going to be swapping a NP205 transfercase into my 89 E350 when I do the 4spd swap. I wanted the low range for backing trailers up hill. But I'm also hoping the added length will let me run a single rear driveshaft.

It sounds like you are doing a lot of the same work to your 75 that I'm doing to my 89 E350. I just wish my van was a 75 instead of a 89! :D

I'm pretty sure he needs 73-79 pedals. I believe the 67-72 are slightly different.

Dads got a pair of mid 79's ford vans in his trees. Neither are 4x4 or manual. One had a 240 in it.

As for the 67-72 pedals. I don't know if they are swappable or not. If they are I might be able to get a set from one of the trucks in dads trees.

I'm setting the 75 up for long distance towing of a 1971 airstream. The guys on the old ford crew cab forum swear by the 460's. But I don't want to feed 7.5l of v8.

I'd rather have a 4.9 with a turbo and manual transmission. Or that dreaded e4od electronic controlled trans.

Overdrive is a must in the final configuration.

I briefly considered a np435 and some higher (lower numbered) gears. But I want synchro first.

I do have an m5od/transfer case sitting in dads barn too.
But those aren't known to be super reliable.

There are OD options with the NP435. But neither of them are real cheap. Advance Adapters makes an OD box. It's basically a small transmission that mounts between the bell housing and transmission. The problem is it's around $1500. Eventually this is what's going in my van.

The other option is what I want in my F450. That's a Spicer/Brownie box. It's a 3spd auxiliary transmission. These were in the older medium/HD trucks. They have an under drive gear, direct drive and an OD. They mount like a divorced transfer case. They are a good choice for a long wheel base tow vehicle. These are getting harder to find. I've found these for as little as $400. But usually they are closer to $700.

For the price the ZF is a good choice. My main issue with it is it has the internal slave cylinder. So when you have an issue with the slave cylinder you are pulling the transmission. The Hydraulic slave set up for the NP435 is external. So if there is an issue you slide under the truck pop a clip off and the slave cylinder is off. And the NP435 is a tough transmission and they are dirt cheap ( I pick them up for $50-$100 ) . If I do have a problem with one I can rebuild it for less then $400. If you have an E4OD and it craps out you are looking at $1500 minimum for a rebuild.

I would never run a mazda transmission in a F250/F350 truck!
