Not exactly.You are dealing with 50's technology and mentality.They used and
dealt with what they had and knew.

Dodge flatheads.
True for the 230 but a 251 will and so can a 265.Both dodge flatheads.The
251 being available in the M37 on my side of the line.

>Increasing compression ratio by more than a nominal point or so will result
in detonation, which will destroy the engine in short order. This is as
silly as the kids who used to attach a string to the governor linkage on
their go-karts to go faster...ever see Briggs and Stratton salad? Couple
this folly with today's crappola gasoline, which detonates with harsh
language, and you will have Dodge salad!
Not true.Apples and oranges.The compression can be increased up to 8.75 on
the flat head.After that there is to much shrouding and it will actually
hurt the flow.Also the motor needs to be in good order.If the block has high
miles and is loose then of course you can have other problems.The higher
compression head was available from the factory.Detonation can be controlled
thru various ways and most of it being common sense.And i bet our gas is
crappier than yours.

It's possible the original is shot but then I doubt it would run.Remove and
resistors and you get a similar effect.Common knowledge to get a hotter
spark back in the 50's.Also filing the gap on the rotor and increasing the
plug gap will give a hotter spark but you can also go to far and not get any
at all.

I don't like to drill the distributer either.

It sounds to me like Jack needs an education.
There is also a guy here in BC CDN who has an
M37,251,lockrites,warns,4.89's,higher compression head,running 900's,stock
carb and intake.He gets about 16 miles to the gallon highway and can pass
the traffic when need be.I'd say he probably can do around 65/70miles an
hour.The brakes aren't a problem because I think he had another material
relined on the shoes.
I am building mine with a crysler crown marine 265,dual intake and
exhaust,higher compression head,and eventually a locker or lockrite,locking
hubs and the Gamma Goat tires(which in effect numerically lowers the gear
ratio)I estimate similar mileage and speed but the power should be around
140HP and 250 FTLBS.
The stock marine 265 is 125 hp with 218 ftlbs at 1600rpm.
I got delivery on my motor a few days ago and I'd say I got a real good
deal.the thing was complete with zero miles on it for $700CDN.
With todays technology almost anything is possible.
