4 bolt main
Lol Bolt. Bolt is the main character. He's the white dog.
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.
1500--2 bolt, 2500 4 bolt
no cause a 4 bolt main has 2 extra bolts on each main
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.
4 bolt their stronger better lasting
That would be a 4-bolt engine in that truck.
None. The four bolt main block is thought to be more rigid at higher loads.
