Corvette comparisons
So there is a 98 mn6 coupe 80k miles and an 04 z06 also 80k miles..
The z06 produced 420hp to the wheel with exhaust and headers and a 430ish cam.
The 98 coupe then imitates the z06 setup.
Zo6 heads, z06 intake exhaust headers and slightly smaller 229ish cam and barely produces 400 to the wheel...
I know the z is given the 50hp more out the box, but the 98 replaced the main difference which was intake and 243 heads, that should have given both cars similar startin points... With similar mods how come the Z still produced more ? Are the z blocks just that much more awesome? Can someone shed some light for me here? Just curious thanks

Could cam make THAT much of a difference? Same tuner also.. Could the 3pin MAF make the big difference? I would think if It did maybe for only about 5hp

And maybe the cam set up could have been a little different maybe, but it's not real difficult to get similar results when the mods are simular.

To be honest I've seen many builds with both cars, and everyone of the cars can produce different results, if you mod the ls1 with the same intake cam ect, and even not changing the heads but keeping everything by else the same, there will be some that are very capable to produce very similar numbers and probably some that will produce more, I know that sounds strange, but every car is a little different, I've seen builds by the same shop, build ls1 and ls6 motors without head changes, but using most all the same parts and some come up with very close to the same results.

My friend, I, By far am not the guy to advise you on this, I'm just relaying things I've seen, but call someone like Stephen at Englandgreen or any of the several capable shops that specialize in our cars, I'm sure they can give you much more reliable advise that you can count on, but remember every car can react a little different to mods, when We did my car I was told that swapping heads was not a great bang for the buck option that resulted in great gains, although you can in most cases pick up more power, IMO gaining up 15 to 20 horses is not worth the cost of swapping heads unless you need every bit of horsepower available
