What else can I help you with?
How do you tell either four bolt or to bolt main on gm engine 1024388 without removing the oil pan?
Generally, you can't. GM installed both 2 and 4 bolt main caps on many different cylinder block castings. Now, some blocks were never offered with 4 bolt mains. Any low performance displacement (262,267, 305, 307, etc) always had 2 bolt mains. Small journal engines (pre-1969 chevy small blocks) typically had 2 bolt mains even on performance engines.
What is an L82?
A L82 is generally regarded as a 5.7L small block chevy, they were the base engine in many corvettes of the late 70s and early 80s.....I believe they had 4 bolt main bearing caps for a performance advantage too.
Is an 89 Chevy 350 block 4-bolt or 2-bolt main and what side is the dipstick?
On a motor 4- bolt or 2-bolt refers to how many bolts are on the main cap what holds the crack. when it comes down to it if your not putting a supercharger on the motor or making to a performers engine, you don't really need a 4-bolt main An 89 would probably have the dipstick below #6. It would most likely be a 4 bolt main, but not guaranteed.
What is the difference between a 2-bolt main 350 and a 4-bolt main 350. Will a 2-bolt hold 500hp?
2 bolt vs 4 bolt main. A 2 bolt has two bolts holding the main bearing caps on. A 4 bolt has four bolts holding the main bearing caps on. A 2 bolt will not withstand 500 HP for a long period of time. note: 500 HP is an incredible, almost impossible amount of HP to get out of a 350. It can be done but you'll need lots and lots and lots of money. That is an addon yes 4 bolts is what you need !!! Don't even try with two bolts or it is going to blow. Well I have seen this little baby to hit 560 HP with a 250 Shot of Nitrous but yes it will cost a little more to do that Nelson Racing Engines has a Small Block Chevy 355 twin turbo, putting out 800 HORSEPOWER. Now this is not an all out race engine, it is part of their daily drivers series, it can be beaten every day of the week, driven to work, abused on the track at the weekends, and survive. Small block Chevy's are some of the most powerful, and toughest engines on Earth. Rod Saboury is putting out 2,400 horsepower in his 1963 Corvette, with a 427 small block, and yes, a 350 can be bored and stroked to a 427 with major block clearancing for a 4.000"+ crankshaft. Whats the hang up with a 4 bolt block anyway. I have built many 450-600 HP 2 bolt engines. In fact the stock 4 bolt setup is been proven to be weaker than the 2 bolt due to where Chevy placed the outer main bolts. They are placed in weakest part of main saddle/block and will stress crack easier. An ARP studded 2 bolt block would be stronger than a stock 4 bolt. Plus the caps will break before the # of bolts matter really. If your looking for the strongest setup then you want a 2 bolt block and have it machined for splayed 4 bolt conversion then use billet splayed caps, with ARP studs
Motors used in NASCAR?
NASCAR uses many different engines. but in the sprint cup series. ALL SPRINT CUP CARS use carbourated Chevrolet 350 4-bolt main small block V-8s, bored out to 358. which is 5.7L. approx 800 horsepower.
What is the biggest engine that fits on a 85 caballero or El Camino?
Go with most any GM small block, you can go bigger of course but that will require some major work. i.e. engine mounts, front suspenstion and transmission with a combination of many other little thingsGeneral Engine Block SpecificationsWhile 6 different bore size blocks have been produced, the small block engine can be classified into 3 bore sizes and 3 main bearing sizes. 283 blocks (3.875" bore, 2.3" main), 302/327/350 blocks (4" bore, 2.3" or 2.45" mains), and 400 blocks (4.126", 2.65" mains). In 1968 the main bearing saddles were increased in size from 2.3" to 2.45".CIDYearBoreMain Cap26219753.6712 bolt ONLY2671979 - 813.5002 bolt ONLY3051976 - 963.7362 bolt ONLY3071968 - 733.8752 bolt ONLY3271968-694.001 (2.3" main)2 bolt3501968-884.001 (2.3" main)2 bolt26519944.001 (2.45" main)2 bolt3021968-694.001 (2.45" main)4 bolt3501968-964.001 (2.45" main)4 bolt4001970-724.126 (2.65" main)4 bolt4001973-804.126 (2.65" main)2 boltNotes: 2 bolt ONLY means just that,. otherwise 2 or 4 bolt can mean either design...
351 big block taking out. replacing with 351 small block. will the transmission line up?
There is no such thing as a "351 big block". ALL Ford 351's are considered small blocks, tho the wacked terminology of "351 big block" is mistakenly and continually repeated by the un-knowing and by many who should know better. Ford Motor Company considers ALL 351's small blocks; 351W, 351C, and 351M. Ford made a 352 big block (FE block like 360, 390, 406, 427, & 428). If that is what you meant, no the transmission bolt patterns are not the same. The 351W and 351C both have the same trans bolt pattern but the 351M has a bolt pattern like the 429 and 460.
What is the difference between a 2 bolt main 350 and a 4 bolt main 350 Will a 2 bolt hold 500hp?
The difference between a 2 bolt main and 4 bolt main is how many bolts hold the caps that hold on the crankshaft. (A 2 bolt main has 2 bolts to every cap and the 4 bolt main has 4 bolts to every cap) A 2 bolt main should be able to handle 500hp as long as you don't push it above 5500RPMs.
How can you tell if you have a 4 bolt main block without tearing it apart?
You could try checking the block # at mortec.com, but there are so many #'s that came in 2 or 4 that you will probably still need to pull the oil pan down to know for sure.
How many Chevy small blocks are there?
350 and under are small blocks. There is also a 400 small block but there is a 400 large block. 396 and up are big blocks.
How many small cubes are left in the block?
To determine how many small cubes are left in a block, we would need specific details about the original block's dimensions and how many cubes have been removed or altered. For example, if you start with a block composed of 100 small cubes and remove 20, then 80 small cubes would remain. Please provide the dimensions or the number of cubes removed for a precise answer.
