[DML] Re: Capping off injector ports

["content22207" <brobertson@xxxxxxxxxxxx>]

Easiest way to cap off the injector ports would be to replace
injectors with 3/8" or 10mm bolts in stock injector boots. Button or
socket head styles would be fairly unobtrusive.

Without increasing displacement or compression, performance isn't
going to change dramatically. More agressive camshafts help somewhat,
as do exhaust headers. Interestingly, larger diameter valves can
sometimes LOWER performance.

The biggest advantage to a proper carbureted manifold is ease of
maintenance. The PRV was not originally designed for the fuel
injection it ultimately inherited. In carbureted form, the ignition
distributor is totally exposed. Hose clamps in back of the water pump
are exposed. The heater core return nipple(s -- some engines have one
on each side, as does my B27F) are exposed. Of course there's nothing
to tangle with the spark plug boots. My little brother timed me
removing the intake manifold on my new A series engine -- 1:25
minutes, carburetor still attached. That's why I hope to some day
install it in a DeLo for comparison purposes.

Note that the B280 uses an intake manifold much more similar in size
and shape to the original carbureted ones.
