My 1985 IROC came as a carbed converted car. The TPI and harness was given to me in a box. Can anyone give me a good source that would help me put things back correctly. I'm a TPI newbie!

 

This website is one of the best sources. Just do a search and start reading!

 

what kind of box? is it new? old? what came with it? etc..... was it from another car????

 

A wooden box...LOL! The former owner of the car pulled the entire TPI system including wiring and carefully packed it away in a wooden box. Basically the wiring consists of everything from the passenger side of the car. The car currently runs off the drivers side harness. Now I want to put the TPI back in. I have no problem with the mechanical side of the swap, just the electrical/ECU.

 

thats good that u have the harness... as far as the driver side connections, there r quite a few.... i wish i could label em for u cause i just pulled mine from my 85 iroc..... ill try this... ill try and send pics of mine and tell u what their for..... what year is your car again???

 

i mean, what is the year of the car that the engine came from?

 

The car is a 1985 IROC. Originally a 305 with a five speed. The 350 block is from a 1975 vintage. Not important in NM. The engine must be up to 1985 standards. The harness is the original. The car is a 350. I have purchased the larger injectors for a 350 and have an adjustable fuel pressure regulator. I have a Superchip for a 350 in the ECU and a couple of custom made chips I will try out when it gets going. I have Vortec heads on the 350 so I guess it's time to hunt for a Vortec base. I'm on a very strict budget so I looking to get by without much for now and upgrade later as far as performance goes. Emissions testing is driving the need to go back to TPI. Not enough unscrupulous emissions testers to go around. Actually I am green conscious and the car has passed tailpipe emissions standards. Needless to say, it will never pass the visual.

 

u need to get two books: tpi swappers guide and how to tune chevy tpi engines... i have both and they r great!!!! they have the info u need to get it running....

 

There was no 305 5 speed TPI in 85. What the 8th digit of the VIN number on this car? That will tell us what the orginal motor setup was in this car.

 

he's saying he has a 350 from a 1975 but his 85', like mine, came with a 305...... mine was swapped for a 350 last year.....
