I have a buddy that has a 1995 350 with a TB on it, his son gave him a TPI off a 305 . He has every thing except for the ECM and the MAF sensor. Will this fit and what wiring harness will he need. Thanks for any info

I thought they were using CPI by 1995. If that's the case, that 305 TPI will need a lot of work to keep up with a CPI. I have read that they work really well. You will also need a different base for the TPI if you plan on using the stock heads as they are most probably Vortecs. My vote is to stick with the CPI.

It sure looks like the TBI to me it has the spray knozel on top and you can see the fuel being injected it to the TB. What is CPI ?

CPI stands for "Central Port Injection". Check it out. This one is off of a '99/

that is not what he has on his 350 now it looks like a TBI, He never saw what it came out of but was told it was a 95 blazer.
