Hi Dan--

First off, if you are going to mess with swapping in a Mopar "A" block, I
would suggest you try to round up a 360 rather than a 340 or a 318. As for
heads, the good (W-2) 340 heads from the late '60's are just about
unobtanium here. Other than a set of those, you are really better off to go
with aftermarket heads, which are easily and economically available
here--don't know your situation in that regard in Oz, though.

There are definitely factory injection set-ups for the 360 available over
here, at LEAST TBI type stuff. BUT--I rather doubt that any of them are a
good match for any of the decent flowing heads. A call or e-mail to "Mopar
Performance" might be of great worth to you in sorting out the details as
to what is out there in this regard and what works well.

If you are not after quite the level of performance I am implying with
these leads, there is an outfit over here called Clifford Performance who
make all sorts of performance goodies for Detroit's in line engines,
including the 225 slant six. Their stuff could easily wake up your existing
225 six to where it runs as well as a normal cooking variety 318 or 340!!
This might be a far more economical and less labor intensive approach if
that is all the more power you are after! Headers, a cam, a bit more
compression, a bit of head work, and a four-barrel intake with perhaps a
Holley four-barrel digital Pro-Jection could make for a 225-6 that would
get your attention pretty effectively!
