Trying to sell a complete TPI setup for my buddy. Do not know if its 305 or 350 and I can't remember how you tell the difference between the two. Also how do you tell the diference between a speed density peice and a MAF?

 

Uhhm... look for a MAF sensor along the intake path?

 

How complete is this TPI intake? The 85-88 is one style and the 89-92 is another style. But 85-89 is MAF and 90-92 is MAP. 85-88 has a cold start injector on the driver's side. The 90-92 have an extra vacuum port on the back passenger side, and a screw hole for the MAP sensor bracket. 85-88 have a different throttle body than 89-92, as well. Lastly, there is no difference between a 305 unit and a 350 unit, except the injectors. A 305 has 19lbs injectors and a 350 has 22lbs.

 

ECM's are different, MAF has 2 ECM connectors and SD has 3.
memcals are different for 305 and 350, you can run the numbers on the memcal to see if it's a 350 or 305 program.
Knock sensors are different as well.

 

How do you identify between injectors? Number printed on them?

From what I hear its a complete "turn key" set up, I am going to try and make a trip up there Tuesday if I can and get pics or identify it.

 

The injectors are right out in the open. They go into the bottom of the intake or top of the head, either way you want to think about it.

 

I meant how do you identify between the two injectors as in 19's or 22's not how do you identify what an injector is...I know what an injector is and what it looks like LOL.

As is are they marked 19 or 22?

 

Yes there is a number printed in tiny font on each injector. Get that number and do a google search, you'll find something to identify them online.
