You sound like Wes.

Let me point out the obvious. If you or Wes had put up a build with AFR heads there would be 39 posts by now. Wes's post fell off the charts, and so will yours. Interesting huh?

OK, I'll be the guinea pig. I'm not afraid of the shit I'll get from everyone for my responses. I'll let 'em hang.

If my car is a stick I'll take motor number 1. I like the torque coming up through the gears and still have great power on top.

If my car is an auto I'll take motor number 2. I like the high power on top, and with a high stall converter when I nail it the revs jump straight up over 5000 so everything below that is moot IMO. As long as the street manners are good, I'll take this engine and a high stall converter.

Is there a purpose to this thread, or are you trying to bait someone into a futile argument?

Now we'll see the posts climb and find out which one is better. Anyone in a gambling mood?

I thought he was implying that a drysump system frees up power.

its an apples to apples comparison. so much for that sotp's horseshit where certain engines won't come alive till 3500. the ignoramus's running around yapping about how afr heads will magically give you all this amazing torque and horsepower just by using the "golden head". the second motor is much more exotic and makes a hair more power with all its unneeded parts like dry sump, eliminator series competition cnc ported heads and customs stroke were a basic 383 with ported factory heads can produce almost exact numbers with no tricks up its sleeve. so to a certain pecker checker, take that flow numbers and dyno sheet and stick them where the sun doesn't shine.

Must be in the water around here. OH, btw, the HP difference was a result of the dry sump, otherwise they were the same. Wonder if those were the LT-4 heads from the David and Goliath article...oh man that was funny even for me. I remember with fondness how we were told how much more power....ah never mind.

So, on one hand you have a D&G article, on the other you have real live dyno sheets. Which do YOU believe? Fact or hype, you decide.

I don't like where this thread is going. Infact, I don't like your tone, Pr0zac. You are on notice. One more pointless thread like this, one week vacation. Understand?

The only "horseshit" I hear around here is this constant hard-on you two have for bashing AFR. Nobody here is beating their chests and singing the praises of AFR. So I don't have a clue who you're arguing with, and its obvious to me there's only one way it will stop.
