I was sure those heads were EXPEN$IVE, just thinking out of the box a bit.  Always keep in mind, "speed costs, how fast do you want to go?"  I sure do like the options of keeping things as open as possible, since meeting classs rules seems to drive the prices up too.

I don't know how strict they are on what is considered a "specialty head".

That gives me another thought What if you put a sparkplug in a diesel head? were there any early four cylinder diesel engines that we could play with and make gas engine out of? Might get some SIZE out of it that way> GPster

John Deere made some big 4 cyl diesels, don't know if
they are old enough for Vintage.

The cool thing about them is the Cadillac cylinder heads
have the same bolt pattern.Only the dowels are different.
So running on gasoline would be no problem.

I wonder if they made a 6 cyl, that would be closer to the class size limit ?
The 4.5 liter 4 cyl is ONLY 275 cubes. The limit is 325.

One thing about the John Deer blocks, they are THICK. I have bored them as much as .150" over without problems in field tractors, and They mill the deck as much as .250 for more compression in out of field tractor pulling. With a little more stroke you should be near the limit.

No good, the first John Deere 4 came out in 1961. :cry:

Every time I read it I see something different. The four cylinders are limited to 220". If you get bigger than that you're running with/against the sixes and eights. We need to investigate that "corn Binder" engine more that we were talking about last night and go for the cubes that way. How big is it and is in older than '59. If we start looking at a class that's running over 120MPH (?) we maybe ought to have the longer wheelbase we'll nee to get a longer engine infront of the firewall. GPster

SCTA rules are like that.  

Really need a current rule book.

In V4 and V4F: pre '35 4 cyl are limited to 220"

In XO, you would be against the 325" limit.  :(D)  Good luck.


Remember the 292 Chevy 6 cyl truck motor ?
Or the Ford 300" six ? When did they come out ?

The '59 cut off was probably picked for a reason.

Did Frank say the IH motor was 275 cubes ?

I have a 41 Buick Straight 8 sitting in my parts car out at the ranch if that is of interest to anyone.  I think it is a special so that would make it 248 inches so probably not a good fit.

Searching on Inliners.org the 292 Chevy seems to be early 60s.
No idea on the Ford 300 so far.

The straight 8 came in 3 displacements, 248, 263, 320

There might be other differences between the big
and small straight 8 motors, besides bore and stroke.

292 chevy came out in 63 300 Ford was 65

The International I have is a 57 Blue Diamond 262 cubes.

The Chevy and GMC heads have siamese intake ports,
which ultimately hurts performance.

How does the IH cylinder head compare ?

Any ideas on the stock bore/stroke ?

I just went for a quick look and couldn't find any pictures but they also mentioned a Black diamond group which is larger and a Red diamond group that has its smallest one at 372". Imagine that in a Metropolitan. GPster

I'll have to dig out my books for that info. I think it's a 12 port head.

A Monza 2+2 would be a nice body, for aerodynamics,
it has to be be smaller than the '53 Stude.



Imagine it with the front stretched, and the roof chopped.

Might be easier to find than a Opel GT, or Metropolitan.
