I'm throwing a 6.0L LQ4 in my Camaro, and along the way I'll be scooping up a cam package from Texas Racing. I'm thinking about getting the 228R (228/228, .588"/.588" 112 LSA) with the COMP 918 springs and chromoly pushrods. I'm probably leaving the cast iron heads stock for the time being because, simply put, I just want to get the motor in the car and running. I might put some 317's on it later down the road just to save weight, or some 243's. But for now I probably won't touch them.
Now the real pooper is that I have to use an Fbody intake. I have a stock LS1 intake that will go on the block when it goes in the car, although I know they don't flow as good as an LS6 or FAST or other aftermarket intake...that's all I have the money for right now.
So with the cam only, on stock heads, and an LS1 intake manifold, going through long-tube headers...what kind of numbers do you think I will be looking at. It will be a T56 trans, so the drivetrain power loss won't be anything like using a 4L60E. The rear end has 3.42's, and the car is factory weight, a few pounds heavier since it's a convertible.
