    I just had a friend stop by and asked if i would trade my 350 for a tune-port setup from a 86? camaro (305-will it fit a 350?). The motor is the stock one that came out of the Jimmy when i bought it. It ran good when i pulled it, and he said the TP setup comes with everything, Whaddya guys think? Thanx in advance.

    if it is a spare motor i would say sure.

    you will need a new chip to deal with the added fuel needs of a 350 (i assume u put one back in after the one trading to your buddy was pulled)

    If it is '86 u might have to redrill some of the intake holes. just "hone" them out a bit. nothing major if you can swap a TPI on...

    If it is an 86 then it uses the MAF sensor which is not really a good idea off road. You will want to convert it to MAP and change the CPU to a '7730. Not a small task but there are lots of people who have done it. Another benefit of of the 7730 is you can run the code and memcal for the 91 trans-am 350 gta which is considered the best for high performance engines and remove the cold start injector which is a PITA for some.

    The 305 TPI came with 19 lb/hour injectors. The 350 TPI came with 22 lb/hour injectors. If you're planning to run a bigger cam and/or spend much time in the upper RPM band, you'll need to upgrade the injectors. Other than that, they're the same setup. Since it's a MAF system, be SURE to get the MAF sensor to go with the setup. That little sucker costs around $400! /forums/images/icons/shocked.gif
