Should have it running this weekend hopefully.

 

Nice I'm curious to see how much they'll pick up over your old heads...

 

Pretty consistant with mine. Your's beat mine at mid lifts where it really helps, but I got a more at high lifts. Mine were done in December 06, so it looks like Lloyd had figured out how to improve mid lift flow even more since then. But maybe this could be within bench-to-bench variation.

Here are the intake numbers (CFM) for my bare LE2 head, head with stock intake, and head with ported intake. Last column is exhaust, head only. Conditions are 28 in H2O, corrected:

Lift.....Bare.....Stock.....Ported....Difference.. ..Exhaust
200....130.9....140.7.....139.8.....-0.9............106.8
250....165.6....167.3.....167.4.....+0.1.......... ..126.4
300....197.7....193.0.....197.5.....+4.5.......... ..141.6
350....224.4....210.3.....219.7.....+9.4.......... ..156.7
400....244.8....230.7.....235.4.....+4.7.......... ..167.4
450....260.5....241.7.....244.8.....+3.1.......... ..175.4
500....274.6....247.9.....254.2.....+6.3.......... ..185.2
550....280.9....254.2.....257.3.....+3.1.......... ..190.0
600....284.0....258.9.....260.5.....+1.6.......... ..193.6
650....289.4....257.3.....263.6.....+6.3.......... ..N/A

Did Lloyd flow him on his bench too? Eitherway, badass flow #'s do you have any dyno or track #'s?

 

No, they were done at Motorcity Muscle (D&S Machine). I was really happy with the flow, too!

Motor still going together, I just got the rest of the $ together so it will be several weeks before VRE finishes my 383 shortblock. Ordered it friday. Then I'll put the car together, debug/tune, and finally run it.

I mostly street drive, but I go to the Milan/Lapeer tracks a few times a year. Street tires, though. I could rarely pull a 2.0 60' on stock motor, and 14.1 at 99ish. So no spectacular numbers to be expected, but I'll share them anyway. I still hope to drop 1.1+ seconds on the motor or I'll be disappointed.

 

Got to the point were the first thing I look at is how heads flow @ .400. 246cfm from LT1 casting is exceptional. Think those heads are better than you think.......They are capable of quite a bit of power if the rest of your car is done right. I'm honestly impressed.

 

Awesome numbers!

 

I've been looking more and more at .200 and .600 numbers, going less on one and more on the other. The midlift numbers just tell you how the chamber shape is, it's that whole 25% of the valve diameter rule.
