Don't waste your time and money on a header. The stock manifold is good to 150 hp before a header has any significant advantage.

 

Header...

 

Noisy

Expensive

Leak at collector or gasket

Hotter under hood temperatures

Always rust in a few weeks and rust out in a few years.

Say they fit but never do perfectly.

Even on a mildly worked engine don't do anything because the stock manifold is good enough.

 

Only good thing about a header is they are lighter.

 

 

 

KA oil pump the best thing for an old engine. I always run them on my Datsuns.

Are the manifolds hard to find? Mines pretty much shot unfortunately.

I seen your post about the pump a long while ago and the opportunity arose and I took it I greatly appreciate that tip!

OK I had a 200k motor and it just need a polish and std size bearings.  Im sure a 70k motor will be fine. I can see a regasket.  personally I would just do a L20 then if your going to waist time opening up a L16

Why would I go to a completely different motor for a few hp? When main and rod bearings are less than $50 together I’m gonna go with new ones. I’m not road racing trying to squeeze every bit of hp out of it. I’m going to be doing the speed limit driving state to state. I’m more about knowing what I have other than thinking when than if. I’m completely restoring the car it’s not a hey I don’t have a car so I’m gonna slap it together. Everything is going through with a fine toothed comb

 If I ever decided to go to a different motor I have a 13b that’s been semi PPorted fully balanced and has aviation apex and ceramic side seals. 😁😁🤘🤘

Thank you very much! I’m very blessed to have it. I respected and enjoyed knowing the man who originally owned it’s whole life. It was it his pride and joy. hoping to have her humming here soon. You have a beautiful set of 510s yourself bro!

They are out there if someones willing to give it up...

Fyi if you decide to use a header get a Remflex intake gasket and switch to studs.... no issue with leaks on mine...

[datzenmike]

Also get one or have it ceramic coated. This will reduce under hood temperatures and extend the life. I think wayno has dealt with a header over an extended period and said that there was some maintenance. Every year or so it needed removal and small cracks welded before they became big problems and hi-temp paint applied. I had one on my 521 back in the '70s and learned my lesson. On a stock engine it did nothing... but cost about $90 in '77 currency to find this out. Took all weekend to install, had to remove the torsion bar to get it in. Had to dent one of the pipes to clear something. The collector pipe flange bolts came loose like clockwork every 3 months even with lock nuts. Some of the above may have been from inexperience I admit. I would have put the cast manifold back on if a/ it didn't mean tearing the truck apart again and b/ by then I had thrown it away thinking I didn't need it. What a debacle!

they not differernt allmost bolt in if you have a 200mm flywheel.

L16s are fine and almost free. to get. L20s lots out there also.

 

if you have a 13b ported find a RX3 to put it in. My buddy needs one for his 74 Mazda Pickup

On a good day an L16 might make about 70-73 hp. An L18 about 10 more and an L20B about 20 more. That's over 27% increase!!! and the larger 25% displacement and longer L20B stroke gives a kick in the ass increase in torque too. All you need do is slip the 510 oil pan on and a 200mm car flywheel and it is the very definition of 'drops right in'. 

 

You would be hard pressed to wring 20 more hp out of an L16.

[Markimusprime56]

I’m really looking into putting the new Cummins r2.8 in it after seeing the dimensions.. hope everyone is doing well I’ve got my block back from the machine shop and fixing to start gapping some rings! 😁

It’ll be plenty of hp and mpgs for a few thousand mile trips till I decide to deck it out 😁

Such a easy swap in these things with a angel Motorsports swap kit. It’ll sit in her crate till her day comes 🤘

Welcome & nice project!  I will have a stock cast iron exhaust manifold, HOWEVER I do not have any more downpipes (long NLA NLS unfortunately)!  If that is yours in the pic, use it!  PM if interested!

 

IF that is NOT yours in the pic, what do you have that you think is not good?

Thank you and very much appreciated! I’ll get you a shot of mine. The holes where the collector of the manifold mate to the downpipe are pretty much completely shot unfortunately. I’ve considered just welding it one piece to a new piece of pipe and just install a new collector just don’t know how well the material takes welds. I’ll get you some pictures later!

also how much would you like for a manifold? 😁

I’m going with a electric fan I’ve got two fatboy fans waiting in the trunk. I prefer just having the lug of just the water pump and alternator. It’s got a really really nice alternator waiting for it as well 😁

[Markimusprime56]

Also fixed the leaf spring hanger  on my f250. I’ve got more parts than time anymore really hoping to have the motor assembled this week.

Motor I built for it 2 years ago.. far from a Datsun I know but it’s a nice ole 351w

[Markimusprime56]

Also rebuilt the transmission last year raysbestos clutches did the 4r100 steel planets and center support plus the snap ring ALL of the upgrades you can do to one of these including the transgo reprogramming kit 2k stall triple disk converter. Man they meant it when they said they’ll hold 1000ftlbs.

Quick question that just ran through my head. Has anyone ever T5 swapped one of these? I’m pretty familiar with them speaking I’ve been through about 12 in my older foxbody days and know of a few available. Hope everyone’s had a good weekend!

Also my car has one of the factory locking gas caps they want a arm and leg for these days but I don’t have the keys.. any ideas..?
