Whats the most power anyones seen theese handle? Were they out of a LQ4 or LQ9? I'm planning a budget 402 with L92 heads N/A in the 500-550hp range, and was just wandering if they will survive.(no plans of nitrous either) Thanks.

 

Im No Expert On This, But Im About 99% Sure That The Stock Rods And Pistons Will Not Work To Make A 402. Longer Stroke Means Longer Rods. Why Dont You Just Leave It A 6.0l And Go On With It.

 

most 402's have 6.125" long rods stock 6.0l rods are 6.096" not even .030" differance. So all i have to do is buy a 4.0" stroke crank. But i still don't know about the strength of the stock components at that kind of power level.

 

so no one knows?

 

do the math it wont work

 

The LQ4 and LQ9 rods are typically stronger, but I'd really recommend investing in a set of forged rods, or maybe some used LS7 rods.

 

What about pistons?
