the number bolts per main cap on a crankshaft journal cap. a 4 is stronger than a 2
.1 litres
It can be n-2 or 2-n, whichever is greater.
the difference or take away
Difference in math means subtraction. To express the difference between 6 and 2 you would use the equation 6 - 2 = 4.
5-3=2 Difference is sometimes used to mean "subtract this from that"
i have a engine with this # and its a 2 bolt main
assuming you mean with the engine intact-code on side of block, code inside glovebox of original vehicle the engine came from.original crank pully will have a marking on it meaning 4 bolt main. not sure what the marking is but its different between 2 and 4 bolt mains.if you mean looking at the block with the heads off the caps holding down the crank have 4 bolts to hold each cap, a 2 bolt main has well...2.
There is no difference, they mean the same thing.
No it wil not. You will have to remove the 2 bolt engine out of the truck and then replace it with the 4 bolt engine. 2 engines will not fit in one vehicle silly wrench puller.
If it's the factory engine, then it will be a 2-bolt main engine.
Yes, there is no difference in block size between a 2 or a 4 bolt bolt 350 in '83, although depending what was in the car before, say a 6, you may have some engine mounting, trans issues, cooling, bracketing, and of course exhaust, hopefully the "2" bolt is a carburetor engine, and of the earlier 8 cylinder design, not a newer generation engine, or your looking at allot more issues. jr
YES. Those 2 engines are the same. NO difference. It is a direct bolt in.
To tell if your engine is a 2 bolt main or a 4 bolt main. Turn the engine upside down on an engine stand. Next, count the number of bolts on each main bearing cap. if there are two, then its a 2 bolt main. And if there are4, then its a 4 bolt main. This applies to the three center caps. The front and rear are always 2 bolt.
should be 4-bolt
That would be a 2 bolt
If its a 1/2 ton it will be a 2- bolt main, You can run the engine # if you need to know for sure. But i'd bet its a 2-bolt
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.
