Re: Four Barrel Engine?? (bsowa)
Four barrels in your carb.
All 76s had a 4 barrel carb. Maybe they meant that they replaced the
original with a performance (like a Holley) carb.
If there was EVER a 2 barrel - then that was the ultimate bubba (mickey mouse). :rolleyes: :mad :confused:
You can check the VIN # against the number on the front tab of the
block, to see if it is the original L82 engine. L82 was factory performance
option. This can also be verified by the VIN # - but forget which digit tells -
and left my book at home. anyone know ??
Good luck - and have fun - you came to the right place to read and learn.
Don't forget to wave... :seeya

Re: Four Barrel Engine?? (bsowa)
I think we might be talkin' 2 BOLT or 4 BOLT here, not Barrel. What is it this person told you, can you give more information about the context of the conversation? :confused:

Re: Four Barrel Engine?? (daily_driver)
Must of been an old timer. See back in days before money, we used to haul around barrels of booze. Could be wiskey, could be burbon, or if you were down on your luck, maybe just a barrels of hooch.
Well some folks just got the cheaper 2 barrel engines. you see, that would only cost ya to barrels of booze. Well, four of the hooch. But then you would say your engine is a hooch scoot and noone liked saying that. But if you got your self a good engine, then that would cost you 4 barrels of booze.
clear?

Re: Four Barrel Engine?? (bsowa)
i think barrel is an old english form of measurement just like a yard or bushel or furlong. just like the standard SBC 350 is a 5.7 liter, well, there is a barrel equivalent. ;) i'm not sure what the liter to barrel conversion is but i'm pretty sure that a four barrel engine is pretty big! :lol:

Re: Four Barrel Engine?? (clutchdust)
they measure oil by the barrelll....
i thnk its like 50 some gallons to 1 barrell!!!
in that case, thatd be a @#@@ huge engine!!!
wowowow!!

Re: Four Barrel Engine?? (clutchdust)
Wait a minute!
I have a two barrel carb on my vette. And it is factory installed.
Let me rephrase that....I have three, count them, three two barrel carbs on my vette!

Re: Four Barrel Engine?? (bsowa)
How come it was a 2 bolt and now its a 4 bolt???
BTW there are 2 types of barrel measeures:
Barrel (US liquid) = 31.5 US gallons
Barrel (crude oil) = 42 US gallons

Re: Four Barrel Engine?? (daily_driver)
So how many cubic inches in a barrel. Multiply that by 4 and you have ... a really really big engine. :lol:
Seriously... 4 barrels is the carburator and 4 bolt is how many bolts hold each cap down on the crankshaft. Some engines are 2 bolt... 4 bolt is stronger and usually (if not always) found on high performance / high horsepower engines.

Re: Four Barrel Engine?? (bsowa)
If it was a real L-82, the factory engine would have been a 4 bolt. refering to the number of bolts used to hold the main bearing caps on the engine.
Check your VIN# on the windshield pillar, drivers side. In '76, if the 5th digit is an X then it was an L-82. If the 5th digit is an L then it is an L-48. (1Z37 L or X)

Re: Four Barrel Engine?? (bsowa)
bsowa, there is virtually no difference in the basic engine between a two bolt and a four bolt except the three center crank main journal caps. a standard, two bolt block will only have two bolts for all five main journal caps. one on either side of the cap. a four bolt block has been machined slightly differently in that the three center caps are made a little more broadly and both the cap and block are drilled and tapped for four bolts, two on either side. the front and back main caps on all factory small block chevrolets are two bolts. BB chevys are a little differnent in that i've seen BB with 4-bolts on all five main caps. a two bolt block can be machined to accept four bolt main caps but unless your putting 350+hp to the flywheel, i don't really believe it is necessary and could arguably weaken the block.
as for difference in performance that is as different as one day is from the next. you can put the same components from a 4 bolt engine into a 2 bolt engine and vice versa. back to the issue of the block though, it is commonly accepted that a 4-bolt block is capable of handling more power than a 2-bolt but i believe that the power levels you would be talking about are bordering on an unstreetable engine.
