It is a small block Chevy 350 engine with 6 bolt main caps.
NO.
Main bearing torque on 98 Chevy 350 4 bolt main?? The main bearing caps should be torqued to 70 ft. lbs.
they stoped making the 4 bolt main 350 in 2002 hope that helps
1969... When they changed to the large journal crankshaft and engine block.
yes
None. The four bolt main block is thought to be more rigid at higher loads.
If it's the factory engine, then it will be a 2-bolt main engine.
On a motor 4- bolt or 2-bolt refers to how many bolts are on the main cap what holds the crack. when it comes down to it if your not putting a supercharger on the motor or making to a performers engine, you don't really need a 4-bolt main An 89 would probably have the dipstick below #6. It would most likely be a 4 bolt main, but not guaranteed.
most Chevy trannys made for small blocks will bolt some additional information .... Chevy never made a 305 with a 4 bold main only 2 bolt main
