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.
If the engine has main studs instead of bolts it should easily handle 400+.
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
remove the seat and the main bolt is there and look between the handle bars and the tank for the other screw.
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.
i have a engine with this # and its a 2 bolt main
