If possible could someone give me an idea of what size injectors I would need for this engine..

Just picked up a fresh LT1 383 with a scat forged crank, H beam rods, mahle forged pistons, comp 503 cam. Unfortunatly the paperwork from the machine shop does not show what PN pistons are in the engine so I do not know 100% what the compression ratio is. PO said it was 10.5:1. With that in mind I have a vortech V1 strim that I want to install and limit the boost to 5psi. With the supercharger on a 355 I was running 42 pound injectors with the vortech FMU to raise fuel pressure under boost.
What size injector would I need for the 383? Right now the 383 is NA and I do not know what injectors are on it, I have to try and find a PN.

Really depends on how much power you intend to make. 60's are generally a good choice though. The Siemens idle nicely and should support what the motor can make at 5 psi.
