Now I've got a few for JLAIFMAN. Did you do anything to the compression
ratio of your Holbayized Series V, or is it essentially stock? I'm assuming
the Holbay cam provides high lift to get the gas mixture into the cylinders.
Are you experiencing rough idle because of the cam? How wild would you
say the cam is? How is your gas mileage? Have you done any 0-60 or 1/4
mile tests? And finally, how is your driveline holding up (clutch, trans,
rear end). Take care, and keep 'em running.

***** NOTES from JLAIFMAN (JLAIFMAN (at) PNM) at 8/11/95 9:08a
As to the exiter wire, I have a tech tip from the Tigers East/Alpines
East newsletter by Nick O'Dell. He used a standard AC Delco alternator and
had the same problem you mentioned about the running on. Rather than a
relay, he installed an in-line diode (Radio Shack part # 276-1141) which
also solved the problem. He also mentioned that the diode only works one
way. So if the problem persists, reverse the diode.
As to my Holbay engine, I only have about 500 miles on it since the
rebuild. So, I have not really pushed it yet to give you any absolute
figures on acceleration and wear and tear. My foot has gotten a little
heavier though and I can feel the additional power throughout the rpm
range. It idles beautifully, compared to both how it used to idle and
other cars in general. The cam I have is the H120 cam which works as
follows: In opens BTDC 58; In closes ABCD 66; Ex opens BBDC 84; Ex Closes
ATDC 40; and lift is 0.33. A stock Series V cam is: 29, 63, 69, 23, and
0.298, respectively. Basically, the cam is not "wild" but more
sport/rally. The pistons were specially made at 0.050 over (1777.33 cc)
and dished to provide 9.5:1 compression. Stock Holbay is 9.6:1 and stock
Alpine is 9.2:1. In addition, I had the head valve seats and guides
re-ground using modern methods to further boost performance. Although
wilder cams and compression ratios are out there, my goal, and I believe
the end result, was to provide a decent increase in horsepower without
losing much reliability or drivability. If I wanted the fastest car out
there, well, I guess an Alpine would not be where I would start. This is
a car I plan on driving until the government will not let me any more, and
maybe then some. If logic had anything to do with any of this, we
probably would not have Alpine's in the first place (or anything else I
would classify as "fun"). So as a corollary to your ending comment -- Keep
'em running with a smile on you face (and bugs in your teeth if possible)!
