THOUGHTS ON GMC ENGINES

One risk of going to a Rally is, your reality gets jerked into some other
area
I was not even thinking about engines when I went to the Amado rally.
and
riding with Manny is always risky business..... :>)

but

*ENGINES*
- if it works - don't fix it
- I know of 3 (current) engines that died from "up grades", causing the
owners to look for rebuilds
- I know of 7 GMCs looking for rebuilt engines - now - which means 10x that
number are possible
- there are only 2 nationally known re-builders - and they are maxed out
- not only are the engines getting older, the re builders are getting
older, or leaving the business
(Dick, Mondello,Lamey, etc)
- we know of 4 or 5 owners who have done more than 3 total engine, R&Rs ,
trying to get a good rebuild
(dan,chuck,jerry,gorgon,nick,jim,etc)
- most of the New/Old rebuilt engines, have to be torn down to see how they
survived
- we know of several who have R&Red their 500's, and 455, more than 3 times
to fix the seals, mains, and intakes, etc
- I talked with 3 Diesel owners, and they cannot tune, repair their own
engines ( GMC, AND SOB)
- an old Diesel is no better and harder to work on
- finding someone to work on your SOB, is more difficult that finding
someone for your GMC
- I know an SOB that spent $5,000 on an engine repair and one that spent
$5,000 on an inverter
*
SOME TOPICS FOR DISCUSSION*
*- there is an out-of-the-box supplier for new, never used, engines (crate
engines) ----GM.*

- Buskirk , and others have used 502 engines, for years
- Tandy has several hundred thousand miles on these engines
- Hal has the stretch, using this engine
- and many more
- they are available in carburetor, and efi , versions
- vendors are starting to think about this direction
-
*ISSUES*
- Manny can bolt-up our tranny to these engines
- You need a pan with a hole in it
- I do not know of any 454 crate engines installed
- there is a move afoot, to use current (modern engines) but the computer
programing is not cheap or easy
- some think 502 engines are not good enough for this use, but there are a
lot of them in place
-

I cannot talk about these issues (not qualified),
but
someone has to start the conversation, (it is a dirty little secret:>)

argggg, why do I go to these rallys :>)

stay tuned, there is much , much, more to come on this topic
Encourage our Vendors

glad I have 2 GMCs, and 3 engines
