been posted in the past? I've had a bout of the flu for a couple of weeks
so that project came to a halt. Hope to do it soon. Since the Caspro unit
is automatic I'd like to have an indicator light that would tell me that it
is working, although no pinging on hills with 12 deg. advance must mean
that its working.

There was an article in GMCMM in May 98 by James Kelly who installed the
Mondello Knock Alert and adjustable timing control. This system varies from
the Caspro system in that it is manual, not automatic. It has a light which
blinks on when the engine is knocking. It also has a sound option. You can
then retard your timing with the manual adjustment. These are MSD units
which sell from Mondello (part #s 8964 & 8783) for about $130 & $100
(although Summit Racing shows 8783 no longer available). I talked with
James about the unit and he likes it a lot. He says that he adjusts it
quite often and enjoys fiddling with it in order to get the best mileage
that he can. He can get 13 mpg under ideal circumstances and averages just
above 10 mpg these days with the 455. Not everyone would enjoy the constant
adjustment but it may be of interest to some of you. Gene, do you think
that your unit will be similar in function to the MSD knock alert?

Subject: GMC: 350 engine block & aluminum heads
Tom wrote some time ago about the 350 engine and the aluminum heads from
Mondello. I think that I posted this previously but may have missed your
responses Tom.
My queries are :
In regards to other engines than the 455, Tom wrote had good things to say
about the 350 diesel block. Assuming that it is converted to gasoline, how
does the 350 diesel block match the torque of the much larger 455?
In regards to your comment about no pinging on the Mondello 455 heads, what
is the factor in the design that allows this? Do you think that the engine
will run comfortably on 87 octane gas with these heads? Is this true of
aluminum heads on most engines or is it this particular design? Is there
any downside to running aluminum heads?
