i need help please
 

hey my name is nick i have a 87 mustang gt 5.0 its the 302, its a stock engine, i just bought the bbk ssi intake. when it was put on i started driving and now when i excellerate the car shakes real bad when the rpms are low or on the lower end of the gear that im in it seems to level out and get smooth around 75 miles an hour but if i just barley push down on the accelerator it shakes but if i gas it no shake, anyone have an answer?

351 question
 

I am trying to figure out exactly what I have. The number on the block is E9AE-6015-AA-7. I know that it is a 1989 block but I don't know if it is an 351W or 351M. I can't figure out what the 7 at the end of the block number is.

Start your own thread......

Where do you feel the shake? The steering wheel? the seat of your pants? the gas pedal? Just changing out your intake isn't going to cause a vibration. What else did you do at the same time?

the whole car shakes but it feels like its coming from the engine

Did you do anything other than removing the intake and installing the new one? An intake swap is not going to cause the vibration.

It would if he didn't use gaskets.

among a few other issues..... lol

you should take that intake off, violently place it in the trash, and put something else on. The SSI is well known for being a piece of ****.
