they stoped making the 4 bolt main 350 in 2002 hope that helps
A real LT-1 had a four bolt main block.
1500--2 bolt, 2500 4 bolt
can be both ,i have a 350 010 2bolt main
no cause a 4 bolt main has 2 extra bolts on each main
4 bolt their stronger better lasting
Main bearing torque on 98 Chevy 350 4 bolt main?? The main bearing caps should be torqued to 70 ft. lbs.
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.
yes
should be 4-bolt
2 bolt or 4 bolt main?? is it stock??
None. The four bolt main block is thought to be more rigid at higher loads.
