Well, that seems like too big a difference to deal with. Back to the sawed off version.......

Jack:
Couldn't you attach an alum. plate (epoxy?) to the intakes on the head and then attach an OZ intake manifold to the fabricated flange plate? Then attach headers to the exhaust using the same fabricated alum. plate?
Mmmmm....

I'm going to take this head
And port down and tap the intake runner with a pipe thread. Then, screw in sleeves and weld a flange acoss the whole thing. No more problems 8)
I could even used the same galvanized pipe the import guy did to do his roll bar
Yeah, that would weld up nice

PVC pipe is easier to work with. No welding - just glue it all together.

Hometown, that would be a bad ass trick if you can accomplish this swap. The jeep cylinder head has a ton of potential!!! That would be a killer set-up.
Very nice indeed...
Just had another thought...
Would it be possible to mate (or modify) the 4 cylinder head (don't remember the name, Iron Duke maybe, but I think that's either GM or Jeep) then do a hacking job/modify for the remaining two cylinders? Just wondering because those little 4 cylinders make so much fukkkkkkin' power! Those heads gotsta be one of the best ever made. The cylinder head is the key to making mo power.
So I think you should go for it warrinting(sp) time and dinero. 258's(cylinder head) are feared in the 4x4 world hometowns.
On a hot rod...

Hi Chevytown,
If your talking about cutting up an Iron Duke and fabbing a head for a 250-292, then ya It's been done. But there are valve train geometry problems.
One that works better is the Mercury Marine 140 head. It looks like a Chevy II 4 cyl. head except that the intake ports are spit. The best part is that the valve train works and the head bolts and bore centers are the same as with the 250.
It would be two cuts and two welds. Gotta build your own intake but that never slowed an inline guy down.

I was actually thinking of the turbocharged 4 cylinder they use on hot Model A's/roadsters and the like. You kinda figure it's been done before. But hearing that someone has is always positive!
The Aussie Crosss-flow head to American block mating trick doesn't need a sleave job if you have the right pistons. Australians used to perform this sort of trick on there ancient 138 cube Holden Sixes. A dude called Merve Waggot used to add a 500 thou steel plate doweled on the block, throw in a custom crank, and end up with 180 cubes. Another Australian guy had a jet boat 350 Chev bowtie block (in his Capri!) which had been decked 125 thou because the class wouldn't allow hi-compression pistons. He just added a 1/8 inch copper gasket and made sure his pistons were the right type so the upper rings didn't do the mambo with the ridge formed. Turbo installations on the Oz 250 Cross-flow had two gaskets and a 62.5 thou spacer plate to lower the compression. So this idea isn't new, and if done by someone with good machining practice, then it works.
Without the pain of doing a foreign exchange, the best option is to use the standard US head and grind the intake off, and add a mild steel or ductile iron adaptor plate. This used to be done in Australia too, but they used a special alloy manifold which took some odd -ball contant depression carbs like Jag style SU and Stromberg CD 150/175. The speedway guys used to consume a large amount of these. Argentina has a special detactable manifold version which is better, but useless if it you don't have one in your posession. The latest Chev 4200 OHC motor has the same bore centres as the Ford (and Holden sixes..looks like the engineers must have copied each other), so the intake mainfold could be made to fit if you can track one down at a parts yard...and make allowance for the fact that it is a cross-flow engine too. The Australian Cross-flow carb manifold has a 3 degree tilt in the wrong direction because its got the carb on the left, and won't suit the right hand side of the US 200/250 without modification.

Babysitter's old man (grandfather?, did not ask) came by to pick her up on Friday night and saw the Mustang in the garage. Of course, he had to stop and talk a while. He had a 64 Falcon with a 200. The best engine Ford ever made, in his opinion. He had some interesting stories, including cutting heads apart and welding them back together. He also installed needle bearings for the mains, rods, and cam in a 351C. Last time he was at the Turkey run, it was on display at American Racing Engines in Daytona.
Since we are talking about bandsaws again:
Way back when, his machinist lopped off the head with a bandsaw and welded a different log on. A European log with 6 side drafts, set to run with 3 primaries and 3 secondaries. Anybody know of any European engines that had 6 side drafts on a log? What I found interesting was the fact that they kept the log. Fabricate a plate for side drafts on the side of the existing log and braze it on?

The learned JD of Oz extraction asked this intellegent question:
"Flying Kiwi.
No offence, but can you send me 1/2 pound of what you're smokin. "
Bro, no offence taken...I smoke Malyasian Rubber! Apply right boot and convert light alloy power into Big Chief Little Skid! Draw Back and Draw Black.
Hope too much thinking isn't illegal in this chat room. My Grey Matter could splatter!

Hey addo, I haven't been up to Rakaia lately. I've got relatives and neighbours who've cruised there a few months ago.
The bridge there has been resurfaced recently by Fulton Hogan, that's all I know. I'm into tar macadams and asphalt in my job. During my recreation time, I check skid resistance by frying my 245 Korean Hankooks with 350Nm of torque..perhaps I should go there soon.
Might get arresested for disturbing the piece. I can see it now, upsetting the peace with a burnout, the Rakaia police man saying "Step outa the car bucko and Put Five On The Fender! I'm XECUTE-ing a search warrant. "
Oh PS Jack Collins... Kiwis are not all as strange as me!

you use Hankook tyres too?
I'd have to say, that dollar for dollar spent, you cant look elsewhere. Mum had a set on her Cielo (OE), they lasted 75,000 km. I had a set of 225x65x14 Optimo Plus IIs on my Wagon, they gave ok grip, but the wear tolerance on them was phenominal - they gave up the ghost after about 40,000km, and they were just under the wear bars then. It took a lot of punishment to get the belts showing through
Jack, come on down! It'll be unforgetable, for all the right reasons!

My old Cortina had a set of 185/82/13 Hankooks which lasted 25,000 km on a runied suspension system.
My Falcon first got GR 60 14 recaps which were absolute crud. My wife simply couldn't believe how ugly the grip levels were with the earlier ones after we got some new Hankooks. The thing hooks up in the wet without trying to do lane changes. I took the opertunity to dial in over 3.5 percent caster when realigniong the suspension...had to shift the RIM plastic bumper forward 6mm to stop the rake hitting the wheels. It runs 33 psi pressures and rides better than before. The most exciting thing is that you can braille drive over kerbs, Jim Beam bootles and big (Michigan-style) potholes without ruining rims.
I still love the look of Rice burner style 17 and 18 inch rims with a lick of black between the terra firma and alloy cruncha. It's especially good when it's not your 18 inch rims that got a king hit from a Kiwi pothole and cost the owner Mega Bucks to fix!

Okay, to recap. Been over a year, and I still don't know the bore spacings of:-
1) Jeep 232/258/4.0
What is it exactly bore spacing wise. 4.375"?
2) Jag 3.4/3.8/4.2 (I know they are Standard-based, and that the 4.2's got repitched bores)
3) Mopar Slant Six engines (same bore spacings as 2.2/2.5L4's, but what spacings)
I guess that's a lot of information...
