yes with link provided it is explained that with machining it can be done but you need to check with the shop if they can machine the block to accept the splayed or angled bolts

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.
305 sbc 2 bolt main
i have a engine with this # and its a 2 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
If it's the factory engine, then it will be a 2-bolt main engine.
can be both ,i have a 350 010 2bolt main
4 bolt their stronger better lasting
That would be a 4-bolt engine in that truck.
That would be a 2-bolt main in that truck for sure.
I can't answer your question but I can say that my 260 hp 350 Mercruiser has 2 bolt mains and a 4 bolt rear main. Go figure! So I take it from your question that you also have 2 bolt mains with a 4 bolt rear main.
