Ok, can anyone tell me what direction the piston rods need to be facing?
The rod caps have a flat side and a radius on the other. According to the info i have found it says to install the rods with the flat side towards the front of the engine. When i went to the machine shop to pick up my engine block, one of the engine builders there that has many years of experience told me to install the rods with the flat side facing each other. So now i am not sure. Can someone help?

 

The flat sides face each other, the radiused sides face the fillets of the crank journals. Do it any other way and you WILL have problems!

 

 

Ok, thank you for your help.

 

Alright, here is another one. My LS1 engine was bored +.25mm over and i bought Hastings +.25mm over piston rings. So i start taking ring gap measurements and Im getting .022 for the 1st ring and .027 for the 2nd ring constantly.
I believe this is to much gap for a daily driver. I am not supercharging or running nitrous. Im using Sealed Power Hyper flat top pistons H868CP +.025mm.

What do you guys recommend?

 

 

Ok, my 98 trans am has the fuel pressure regulator built into the fuel pump assembly inside the tank. The stock fuel rails on the intake has a fuel damper.
I am using an aftermarket manufactured aluminum intake from sharpcustomperformance.com with a 92mm throttle body and stock injectors. Do I need this fuel damper?
