Hey guys im new to SR's. Ive been accumulating parts over the last 2 years and i am wondering what kind of power i will be laying down with my currnet build. Here is a list of the parts that i have.AEM EMSSARD 550 cc injectorsHKS 272 camsferrea 1mm oversized valvesCometec head gasket86.5mm pistonsDarton sleeveseagle rodsARP studs for head,rods and mainsISIS intake manifoldand most likely a peakboost exhaust manifold with a GT 3071RThis is going out to Gord Bush for a full build!

It will be tuned to run pump gas and be a reliable daily driver...So prob around 15 to 20PSI boost right? what do you guys think i should be making roughly?

If you go bigger than 550cc injectors you might be able to hit 450-500whp. The 550cc's are limited to 300-350 on pump gas and 350-400whp on race gas. You don't want 300whp when all your other part choices point to around 500whp.

I think you should try for 500whp! All the other parts will support it reliably except the 550cc injectors.

I was hoping for 400-450 whp myself and i had a feeling the injectors were going to be holding me back so maybe i will get rid of those before i put the eninge in the truck and go for 750 cc injectors.

Thanks for the reply

yea deffinetly need bigger injectors and are you going to be doing anything else other then the valves and cams in your head cause my friend had problems with valve float at higher rpms with stock springs and retainers

Yea, I had to turn up my fuel pressure to about 3 bar to get to 380whp on my 550cc injectors. Recently upgrade to 740cc and hit 400 on my 2871r setup.

Go w/ 740cc minimum and I'd be willing to bet you will hit over 400rwhp under 20psi on pump. That's a beastly setup. With race gas you should easily make mid 400's
