Nice work. It should run well. How high much boost will you run and
how high is the compression ratio? It's unfortunate that pump gas is
a limiting factor there. With that port design, you almost have to
have some kind of forced induction. I would have thought that the
Brits would have figured out crossflow porting by that date.

Now that I've got paint on the engine compartment, I started
cleaning up the motor in preparation to installation. As I document
the progress, I kind of like this shot:

For the motorheads that have any interest in such things, between the
ported aluminum head, aluminum fidenza flywheel, aluminum back plate and
lightweight reduction gear starter, I've knocked about 50 static pounds
off the motor. Other go-fast goodies include the roller rockers, custom
cam, pauter rods, venolia pistons, and of course the supercharger from

In the previous incarnation of the motor, which unfortunately had a
cracked iron head, I was getting a bit over 90hp on the chassis
dyno, and once saw a bit over 100hp to the ground, just before the
head gasket blew. I'm hoping that this version of the motor will
hold together a bit better and put a little over 100hp to the
ground. For people not familiar with MGBs, a rubber bumper
('76-80) MGB would put about 50hp to the ground, a stock '69, like
Jasmine would put about 65hp to the ground. Before supercharging,
I was getting a fairly consistent 75hp to the ground. So an MGB
that puts 100 to the ground is pretty quick for an MGB. Or about
average for a spec miata, which you could buy, or even build for
significantly less than I have invested in Jasmine's motor. It
must be a symptom of the same mental condition that causes me to
shoot with Pentax gear.
