Since you will be living down the street we shall see. If you don't hit your numbers we can always laugh at it together. We can just pack that turd up and take it to AZ Dyno chip and fool around on the dyno. That's after you get the rats and cobwebs out of it. God knows what's been living in your exhaust.

 

haha

 

Lopers speed shop in Phoenix already, agreed to let my use their dynojet for free. I will throw mine on the dyno in like september or october early in the morning so I can get decent numbers and not have 10000 degree intake temps.

 

HOLY CRAP!!! So I just got back from the machine shop, we flow benched the head. Some surprising results (in both a good and bad way). I will let the numbers speak for themselves.

Intake @ 28" water
--Lift | CFM
.100"|90.06
.200"|174.87
.300"|234.15
.400"|260.95
.500"|267.60

Exhaust @ 28" water
--Lift | CFM
.100"|82.78
.200"|145.41
.300"|158.20
.400"|159.80
.500"|161.39

 

If i knew what this meant...

 

It means the intake flows pretty damn good, and the exhaust, well it almost DOESN'T flow at all

 

our exhaust ports blow! there the size of a damn thimble!

 

It means he is a bit restricted on the exhaust side.

 

At certain points in the port, there are actually pockets of VACUUM!!!! WTF IT THAT!?!? GM is funny.

 

Not entirely true. My exhaust side at .480 degrees of lift is 237.69

 

wow that is bad, i took the time to hand polish my ports and i was very disappointed in how small they were!

the intake ports are damn near twice the diameter.

 

Is that your fully ported LSJ head? If so, thats badass and I look forward to getting flow numbers like that... IF NOT BETTER

Whats your intake flow? ~300ish?

 

thats one hell of a port job did they remove all of the egr ports?

 

Also @ .480 it is 282.31 and yes this is my LSJ head for the race engine.

Not to my understanding.

 

damn thats pretty suprising that they were able to get that much out of the exhaust ports without porting out the egr ports.

 

I can ask them the specifics but chances are they won't want to give up any secrets ($$$)

 

figures

 

Yeah, I figured the intake port was pretty good as is from the factory. Thats pretty damn good on the exhaust side though.

 

specs on muh new cams
