1500--2 bolt, 2500 4 bolt
should be 4-bolt
No. Most of them were 2-bolt mains. The 3/4 and 1 ton 350 engines were 4-bolt main engines. All the 1/2 tons had the 2-bolt main block.
2 bolt or 4 bolt main?? is it stock??
4 bolt their stronger better lasting
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.
no cause a 4 bolt main has 2 extra bolts on each main
Most likely not, it'd be only a 2 bolt main.
3970014 350 69-77 Pass,Chevelle,Camaro, Nova,Monte Carlo 2 or 4 bolt main 3970014 350 69-79 Truck 2 or 4 bolt main 3970014 350 72 Corvette late '72,200 HP,255 HP 4 bolt main
You could check the block serial number at mortec.com, but it's probably 4 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
That would be a 2-bolt main in that truck for sure.
