More math I see, you forgot to factor VE, BSFC, BMEP into this equation.

You put 30lb injectors on that 408 and it will run out of injector, I have seen 355 inch motors almost max out 30lb injectors. At or below 7000 rpm.

Unless the 408 is HORRIBLY built with junk heads, the wrong cam and tuned wrong. It needs 42lb injectors.

Here is a link to a cheesy little video I made of the 408. Please Ignore the messy garage and the Crappy exhaust (its temporary).
BTW: Its gonna pull waaaay beyond 6200 I have rev limiter set at 6300 now and it definatly wants more.
I'll keep you guys posted about how injectors do and other odds and ends. hopefully I can dyno soon!

 

I tried a 30# injector...it did fine on the street. When she dead hooked at the track and pulled the wheels it hit the ground quick. Injectors were done@ about 4500-5000 with a load on the car.

I tried again and tried to run them 125% didn't work.

You will need 50 or more. I went with a 60....still waiting on those

 

The car sounds pretty good!! Where are you at in MO?

 

Warrenton about 30 miles west of you.

 

Cool, I'll be looking out for you!!

 

why? dinner and a movie?

 

Nah, just want to run him in my Cobalt.

 

what kinda of FP gauge is that?

 

Please dont ridicule me Its a Glow Shift but its decent for the 30 bucks or whatever I paid for it. As long as it works and reads good...

 

I'll explain it.... SB2 heads!

 

ive actually looked at those before and they look awesome IMO... no ridicule at all.. i was interested in them but didnt know how accurate they are... have u verified its accuracy with a mechanical FP gauge?

 

The car sounds pretty healthy..Gauge isn't too bad either.

 

Sounds good!

Crookedest exhaust I have ever seen!

 

sounds good man
now lets see either some dyno #s or track times
