Everyone has said that the 3.4L has a weak bottom end. I was wondering which part if any individual part is weak. If and when I build a motor to handle NOS then I would like to do something about this so it can handle a bigger shot.

I have heard the rods and crank are forged which is good but the pistons are the weak link.Hot Cammed LT1 Sleeper -

Ok then with forged pistons do you still recommend only a 75 shot or can i go higher. Im not talking like a 150 but could i get it up to 100 shot maybe?1995 Firebird 3.4L M5 Custom Shaved Door Handles, TA front bumper, TA rear bumper, Ram Air hood, 2k C5 18X9.5 Chrome rims, New PPG paint, TA rear spoiler, 2k TA honeycomb taillights, Rear silver pontiac inlay, all silver badging, H4 headlight Conversion kit, RK Sport Ceramic headers, Hypertech Programmer, Rear disc rearend, One piece driveshaft, 3.73s with LSD, Camaro Two tone seats, Custom Stereo installComment

Pistons, piston rings, head gaskets, yada yada yada.
These are typically the weakest links first.
Then things like crank, rods, etc.
If you build a nitroused motor then do everything.
It doesn't make sense to go half way.
Technically having a completely forged motor doesn't mean it is 100% safe with nitrous. Anything can happen but a build motor is, obviously, much stronger.Race car - gone but not forgotten - 1997 firebird V6

Where can i get forged rods at? I don't think they have a forged crank available so what can I do to make it stronger? thanks for all the help.1995 Firebird 3.4L M5 Custom Shaved Door Handles, TA front bumper, TA rear bumper, Ram Air hood, 2k C5 18X9.5 Chrome rims, New PPG paint, TA rear spoiler, 2k TA honeycomb taillights, Rear silver pontiac inlay, all silver badging, H4 headlight Conversion kit, RK Sport Ceramic headers, Hypertech Programmer, Rear disc rearend, One piece driveshaft, 3.73s with LSD, Camaro Two tone seats, Custom Stereo installComment
