How do you get a stock bottom end 383?

No I'm not saying. A stock bottom end 383 I'm talking about the people who say people spray a stock bottom ends with 300

With that big of a shot on stock bottom end it's on borrowed time BUT if your going to do it make sure tune is spot on and you got the fuel system to handle it. With stock bottom end there isn't too much that you can do as far as " protecting" it. That's if that is what you are asking.

No it's not lol I'm wondering if changing the to a 4" crank affects the clynder wall pressure on the ls1 blocks

Heavy H.P.

I've heard of 200 shots on a stock bottom end LS1. Don't know how long the engine lived.

I'm not asking about stock bottom end cars I've sprayed mine with 200 for 3 years now..I'm wondering if changing to a 4" crank will matter and how much people have sprayed a ls1 block with 383 internals 4" crank, 6.125 rods, and 3.905 pistons..and got away with before the clynder walls started to go

Forged pistons...I'd say it would live a long time if not ever leaned out. Same as anything else. Ultimate ultimate setup...maybe not. Damn good. Yes.

With a 300 shot it might melt right away.

^The replies in this thread..

It's all in the tune fellas (enough timing pulled, cold plugs, etc).

Oh okay. Lol. I understand what you are saying. If the bottom end is forged then like shortdog said
