Since this is the first big block that I'm doing, do stock LS5 454s use a fuel pump pushrods, and if so which one? This is the original engine and will be going with original style fuel pump.

I'm trying to get the majority of the parts ready to order in the next couple of weeks.

Use a stock push rod if your using a stock cam. If you are going to use a roller cam you will need a rod with a hardened tip.

Are they same as the small block ones?

bashcraft

Duntov
