If the number 8999289 is a casting number inside a bell the first number is a 3. Then the block that is in question would be a 4 bolt block with 4 main caps.
Hello, what is the size of this engine?
Is the engine that bears the number 8999289 -T12 Engine size is 454 ?
1500--2 bolt, 2500 4 bolt
4 bolt main
i have a engine with this # and its a 2 bolt main
4
should be 4-bolt
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
A powerglide is a 2 speed automatic transmission.
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.
no cause a 4 bolt main has 2 extra bolts on each main
YES
4 bolt their stronger better lasting
