That bad main was furthest from the oil pump and from the factory new SBC oil pumps are only pushing 35-40 psi on a good day, where a SBC should really run closer to 60 psi for a long happy life . I think its an EPA thing and fleet economy and if you reduce the drag from the oil pump (and the v/v train too by going roller) you save x number of million gallons burned on the nation's hy-ways. Most important part of any SBC build is solid oil pressure from a good pump.
yeah, it is common for a number 1 or 2 rod to go out, or I guess even the main since they are the furthest from oil pump. From my experience usually the mains don't go out its usually a rod, but how silly do I sound saying that when I have an engine with a bad main lol. no, but seriously, I have been saying for years the mains don't go out its always a rod journal. In my defense the first like 5 to 10 engines I have dealt with, its usually a rod bearing in the front of the engine 1 or 2. But yeah this is not the first main journal I've seen that was bad. they go out too i guess.
@@davidcraft4909 Ive seen motors where #1 or 2 main bearing shifts but doesn't spin , it's just enough to cover or restrict the oil hole in the block and then the rod thats fed from that main go's dry and spins , its like a main shift takes out a rod scenario.
GENERALLY, to make power in this thing you would have to invest your money in a cam and heads. AFR or Torquer World product heads 043650-1 would work here. The Gm OEM heads for a 305 aren't known to make power.
I'm going to put a gt45 turbo on a stock 305 and go from there. I know the stock heads won't make that much power. The idea is. That if I can make about 250 hp with stock heads and 9:1 compression, and then put a turbo on it and boost 14 lbs, then I should have a 500hp engine and it should make about 500 ft lbs of torque. I'm not saying i know it will. I've never done it before, but that's roughly what I'm doing and the theories behind it, lol.
I wasn't trying to bash anyone. I'm not even trying to bash the 305, but it is what it is. the 305 has 2 major drawbacks the heads and the bore size. I'm actually kind of on a mission to see if a 305 can make any power with a turbo, but I am skeptical. Either way I really enjoy seeing people take underdog engines like straight 6 put a turbo on it and run like 9 sec. I would really like to see more people take a 305 and do something impressive with it. I just talk down on them because they have a major disadvantage and a 350 is actually cheaper to build when you get into forged pistons and head options. I really don't hate on any engine or brand, I like it all. I apologize if i said something in my videos that you didn't like.
I dont think so, it didnt look like a high miler, more like someone was'nt doing regular oil changes , have the crank done , refresh the heads, ball hone the cylinders , clean everything , could be a solid runner.
Great info. Thank you

Stop bashing the 305 people. Bash the heads if you must bash something, because there is the choke point.

The problem is the engine needs $1000+ of machine work. Could have bought a better engine. Its not really worth it. This is a DIY job engine.
