Hello guys
I'am building a 396 LT4 engine all forged, and i need help with some stuff.
First is what timing chain should i run with, i heard that Cloyes 9-3145 is the best option for some real horsepower, what do you guys think about that ?

And i need help choosing injector,what brand? i will be running 80pound injectors,do i need low or high impedance injectors,

This motor will be blown with P-1SC system and i will be boosting about 14psi max, but maybe in the future i will change to F series procharger

My Whp goal is about 600 - 700

I need your help guys to be one of the fastest LT4 on iceland

What exactly makes your build an LT4? Are you using LT4 heads/intake?

The Cloyes 3145 is a great choice.

Low impedance injectors take more current to operate, but allow for a much faster opening and closing injector, useful for the minuscule pulsewidth for large injectors to maintain a tolerable idle. However, they require a high amperage driver (stock injectors are high impedance). You can piggy-back the PCM with a "black box" (www.acceleronics.com, a bit pricey) so you can use low impedance injectors with the stock PCM.

I got a lt4 edelbrock intake and AFR lt4 210CC heads

I will be running stock computer next summer but i will buy Fast standalone in the future,maybe sometime in 2012, I think the best choise is to run high impedance injector with stock PCM and run low impedance with FAST standalone, what do you think about that ?

I'd just run the low impedance injectors with the high amperage driver on the stock PCM for now. The "black box" is far cheaper than a new set of injectors.

The black box is about 300$ right ? , what brand of injectors should i take,

I only have experience with SVOs and Lucas/Delphi injectors, but I'm helping a friend build a 600+ LT1, and he is using Siemens injectors (which I've heard nothing but good things about).

Thank you, i will buy versa fueler , much cheaper and better then high impedance ..
Another question
i will run ATI super damper but i dont know what damper is best for supercharger aplication ..

Blown25th-T/A

someone now about these dampers ? need advice please

Blown25th-T/A

should i take lighter or heavier damper, will be running procharger

You might have better luck in the FI forum...but there is a guy (QC97Z) who frequents this forum with a 600+HP boosted LT1. Maybe he can chime in...
