Dave,
         Good question.  I would think the tolerances would be quite a bit 
tighter.  Before I'd bore an engine, I'd mike the pistons, and each were 
well within .0005" of each other.  +/- .005" would be quite a variation, 
and would require special attention for every piston to every 
bore.  Whereas you bore and hone the block, and then assemble the pistons 
on the rods per left & right bank.

Ken, do you have any pictures of these odd beasts? I know the Holley carbs 
were used in the truck and industrial applications, but I don't know the 
reasoning why. Usually, those carbs didn't have a very high cfm rating, due 
to the low-rpm nature of the application.

Well, guys, it finally happened - I managed to drop the car on myself!
Well, not actually.
First - I'm OK. Everything seems to be in working order, but I'll be 
going to the doctor this afternoon to make sure.
What happened was this:
first, you have to understand my driveway (which I dislike). It goes up 
about a foot in elevation from the gutter, then about three feet from 
the gutter it flattens for a couple of feet, then goes down to the 
garage for the rest of it's 25 feet. About a 15-degree or so angle. I 
normally park the car straddling the hump so that it sits level. 
Unfortunately, this means that the car points downhill if it's jacked 
up at the rear while pointed into the garage. It's not a huge slope, 
and I'm paranoid about using the wheel chocks, even on the rear with 
the tranny in park and the brake set.
I had the '70 jacked up to change out the rear springs (as you may 
recall, I broke a front spring a few weeks back - pics soon, broke the 
sucker right in half! - and took the opportunity to put in a set of 
Edelbrock (by Eibach) performance springs. Front was already done.) in 
the above described orientation. Wheel chocks were in place, jack 
stands were in place, jack was under the rear, but lowered to allow the 
springs to uncompress. Shocks were hanging free to allow the rear to 
drop.
What I failed to notice was that the car had moved rearward as I had 
jacked it up, rather than the jack moving forward (due to the incline.) 
When I got to shoving the first spring in (it needed to be compresses 
just a little) the car started to move forward. Here's the other 
boo-boo: the jack stands were too close to the rear frame kick-up, and 
slid up the curve as the car moved forward.
I didn't quite get my hand out fast enough, and it got trapped between 
the axle tube and the shock absorber, which itself was against the 
exhaust pipe, and possible something else (couldn't see, and I was 
panicking anyway...) Fortunately, the jack stands were trapped between 
the rear tires and the frame, which kept the body from descending any 
further and squishing the rest of me along with my trapped right hand 
(there was only the one spring partially in, you see.) Also 
fortunately, a neighbor down the street was raking leaves and heard me 
screaming like a girl. We tried jacking up, but that made things worse, 
as the jack as under the rearend, and with no springs, just went up, 
pinching more. What worked was leting the jack all the way down, and 
lifting the body by the bumper (he was a pretty big guy.) That got the 
shock loose from whatever was preventing it from swinging side to side 
( the mounting bolt for it on the axle tube, I think) and I was able to 
shove it to one side and extricate myself.
More fortunate news: I was wearing my Mechanix gloves, so external 
damage was limited to a couple of scrapes, and bruising. Nothing seems 
broken, but my hand is swollen up something fierce. It looks like I 
weigh 500 pounds, judging from that hand. You should have seen my hadn 
immediately afterward, though - impressions in the skin from the stuff 
that had been squeezing it. The was a groove all the way across the 
back of my hand from the brake line that runs along the axle tube, 
which was part of the reason I couldn't slide the hand out. The other 
reason was that my thumb was across my palm, which makes one's had 
fatter. The heel of my palm was against the shock.
I probably could have gotten myself out if my neighbor ( I don't even 
know his name - he's several houses down across the street. Have to 
remedy that, I think) hadn't shown up, once I calmed down and shock set 
in so that the hand didn't hurt so much. In all seriousness, that was 
probably the worst pain I've ever felt (I've been extremely lucky - no 
broken bones, and very few hospital visits in my 35 years.) I knew 
something like this had to happen sooner or later, as I said, I've been 
extremely lucky thus far, and it could have been much, much worse.
I've always been pretty careful about proper safety when working under 
the car, but I tell you now that I will be completely paranoid about 
it. I know that entropy and Finagle are out to get me!

Be careful out there, guys!

Kevin,

I am glad that you did not injury yourself any worse.  I did rear springs on a
'72 Vista Cruiser this summer.  It was on a level, gravel driveway .  It is kind
of nerve racking to be doing that kind of work, especially working to compress
the spring pushing against something that is not the most stable..  I did use
wheel chocks and jack stands.  If I had heard your story at the time, I might
have taken even more precautions.

There are many interesting ways to hurt oneself. My brother-in-law was
replacing the universals on his van one day when I stopped by for a visit.
Backed the rear up on ramps and was on the ground under the van. Had a bit
of a fight to get the universal free. The van was in park and the only thing
holding it from rolling down the ramp was the drive shaft.

Went to the hospital after getting him out from under the van. Only cracked
ribs after the differential housing stopped forward motion by using his
chest as a chock.

When do the Darwin awards get released? Suspect I might know a few future
nominees.

Scary stuff; glad you're alright!

That's a tough thing when your jack swings the jack-point on an arc, moving 
either the jack or the vehicle you're jacking. I know that when I put a 
vehicle up on four jackstands that I've gotten into the habit of going back 
to the first side, jacking up the chassis a bit and repositioning the 
jackstand under the contact point so there is no lateral strain on the 
jackstand.

Bob/List,

I bought them about a week or so ago, if you go on eBay, do a search based on 
bidder (you can do this, I check out other bidders from time to time) 
"kckken" (me) and have it show closed auctions.

I'm taking Chelsea out to dinner, later tonight I'll copy the address to the 
particular auctions and post them.  While I'm at it I'll measure the throttle 
plate diameter, they don't look too big.

Bob/List,

Here's the additional information promised on the oddball Holley carbs and 
the auction addresses -- each auction address shows two pictures of each carb:

(Note: the numbers are the secondary venturi diameter and throttle plate 
diameter)

List 6771 (74 Dodge 413): 1&1/8  - 1&9/16
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7927524003

List 6929 (75 GMC 427): 1&5/16 - 1&9/16 approx. 600 CFM
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7927524483

List 6742 (74 GMC 366): 1&5/16 - 1&9/16 approx. 600 CFM
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7927525068

List 6928 (75 GMC 366): 1&1/4  - 1&9/16
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7927525580

I looked up the combinations of sizes and found most of the ones with the 
1&5/16 - 1&9/16 came out to 600 CFM.  I couldn't find anything close to the other 
two sizes, conventional wisdom would suggest they are slightly less CFM, 
possibly 575 and 550, perhaps?

One way or another, I figure the little parts made these a bargain!  The two 
I opened up had "close limit" jets (stamped 562) in the primary metering 
blocks.

Take Care,
