    Few engine questions, thanks in advance.

    If the sound is coming from the top of the engine, it's probably a hydraulic lifter/valvetrain issue. You might also want to check to make sure that you don't have any exhaust leaks.

    Anyone with Spintechs? I have some questions

    How does the side exit fit with the GT ground effects? I was thinking about buying the side exit kit but didn't want to spend the money to find out that it wouldn't work with a gt.

    351 W Dyno Results

    I agree that eventually he needs to change the cam, but it won't solve the problem that he's having right now. First he needs to get it tuned correctly before throwing parts/money at it when the cam isn't the main problem.

    Whats the strength of the 351 sportsman block?

    I believe they are rated at 750 hp, but they will actually handle more than that if built/balanced properly.

    Around 54-5500 on a stock motor should be fine.

    oil pressure

    I liken the factory oil pressure gauge to a woman, they both seem to be telling you what's going on, but you're never really sure if they're lying. In any case, don't trust either of them.

    351 W Dyno Results

    Here's my opinion. 1. Deal with the lean condition first of all. 2. Change the exhaust. A good mandrel bent 2-1/2 inch exhaust will definately help, but don't expect a dramatic increase in HP or torque from just this. 3. The TB is just fine for your setup, I would take it somewhere else...

    Whats the deal...my car revs straight to 6250!!

    Any stock 5.0 will run to the rev limiter, the only problem is that it's not being very productive at that rpm.

    do U/D pulleys harm engine???

    That's what I was saying, most people won't have any trouble if you add U/D pullies. If you do, it wasn't the U/D pullies that did it, it was a problem that you had and didn't notice until it was amplified by the installation of the pullies.

    do U/D pulleys harm engine???

    Underdrive pullies do slow the rotation of the water pump somewhat, but most people don't have any trouble with overheating because of it. The way that underdrive pullies work, is that they use different sized pullies to slow the accessories down, which reduces the parasitic loss caused by the...

    Turbo coupe t5

    I don't know the gear ratios, but I do believe that they used different input shafts on the turbo coupe t5.

    proper break in period

    I've brought a few fresh motors to the dyno, the break in there consists of warming it up and putting a little load on it and varying the rpm's for about 20 mins (cam was broke in before we went to the dyno). Then we did 3-4 short pulls, then let it rip (574hp/509tq in case you were wondering)...

    truck lower

    I believe the holley systemax upper uses a lower that is close to if not identical to the 302 truck lower intake. I've never compared the 2 side by side, but have seen both and they sure look to be pretty much the same lower intake to me.

    Do I NEED TO CONVERT OR STICK WITH SPEED DENSITY?

    Yeah, I just had to remove the oil baffle below where the filler cap is, and grind a little bit off of where the baffle was mounted.

    motor specs and various questions

    I would say that motor should make around 200 hp (+-10hp) if tuned up correctly, even with the crappy e6 heads. I believe the compression is the same 9.0:1 as the HO motor was.

    Do I NEED TO CONVERT OR STICK WITH SPEED DENSITY?

    Your car should run just fine with those mods, mine does you can see what I have in my sig. California cars had mass-air in 1988 while all others were SD, all mustangs starting in 1989 were mass-air.

    Help with rear tire size. Please read. Need traction!

    No rubbing with 255's and the quad shocks. My cousin also has 255's on his car with the quad shocks in place and his doesn't rub either.

    351 EFI swap..

    That block would be a non-roller, the 351w wan't machined for roller lifters until mid 93. Your driveshaft will work, but I believe you'll need a new oil pan. I belive those years were rated at 205-210hp and 330 lb-ft.
