ok i have a golden eagle sleeved 85mm ls block, weisco 8.25cc dome top pistons, eagle rods, gsr port and polished head, rocket motorsports valve springs and retainers, omni flat faced valves, rocket motorsports **** camshafts, twm 52mm itbs, 440 injectors, the compression is going to be around 14.5:1 -15.0:1, running on 116 octane. im looking at headers and cant decide on what would make more power. the two im looking at is the rmf narrow header, or the hytech tri-y big tube header. which one do you suggest is better for the setup? this is a track car that will never see the streets.

 

In all honestly, if you spent all that time and money on your build so far, I'd go that little extra and have a custom header from Hytech/SMSP/SSR etc built for maximum benefit. Going with a generic replica is like restoring an old car and then using a spray bomb to paint it...

 

Without a doubt.

 

ok well will the 440cc injectors be enough for the motor?

 

 

Go to RC engineerings website for a fuel injector calculator. 440's might be on the small side...
Supposedly Injector Dynamics injectors are the new hot ticket. 5-6 whp throughout the rev range!
Might be worth looking into.
Depends how much you got to spend on a header and how much time you have.

 

440s should be fine.

 

I have heard this, but have not seen the dyno sheets to prove it. I would love to see before/after with no other changes. I would buy a set.
