@bman31324 But you are denying that the valves are floating at 7k on a stock drivetrain. Btw, you could have an aggressive cam, short runner intake, ported heads, 75mm TB, 90mm MAF, ect. and still have trouble making power at 7k because of valve float (if your running a stock vavletrain). Trust me Bman, I know what I'm talking about. Not only is it not making power at that rpm, but your putting an extreme amout of wear on your valvetrain. If I was you I would keep it under 6k from now on.

@sniper1334 im not saying that it wont make more power at 5500 than at 7

[sniper1334]

@bman31324 That proves nothing. If you're running a stock valvetrain you ARE floating your valves at 7k. It's not questionable, it's a FACT. Ask any experienced engine builder familiar with Mustangs. You would need some expensive valvetrain upgrades to not be. Also in order to make power you would need a cam for that rpm range and other supporting mods. MAF, Injectors, ect. Put your car on a dyno and spin it to 7k, I bet it will be making more power at 5500 than at 7.

@sniper1334 actually no you wouldnt ive run my 88gt to 7200 racing and ive hit 7000 a few times in my 90 lx 5.0

[rb72422]

I don't even go to 5k on mine

[sniper1334]

You'd be floating the valves like crazy at 7k.

that steering column looks nasty

@a90351cleveland um yeah meaning they didnt know that when they swaped the motor in and never switched it. so as i stated about. 4 cyl tach

[a90351cleveland]

@jds95sx actually that is quite incorrect reason a.. the 4,6,and 8 cylinder all have the same cluster but.... theres a little switch at the bottom thankyou thank you... and b.. well if it was turned to 4 cyl its idle would read about 2 g's and at six it would be like 1700 Thank you Thank you ppl... im here all day lol

Yea those tachs are so off, i put a 5" in autometer on the side of my cluster and reads so much more accurately. Plus im pretty sure those ecm's shut down at like 6250?
