Project MULE - 350 Vortec Tuned Port Injection build on 91 Suburban.
(UPDATED 07-05-2014)
We have found out our Suburban (as great as it is) is just out of power when loaded down and hitting the hills.
We decided to go with a SBC just due to the fact I found one real cheap and I don’t have to switch much of anything on the truck. Other engine ideas were explored, 5.3, 6.0 7.4 vortec and even the 8.1. The deals I ended up with for the main parts of this project just said “SBC”.
Below is the initial list of parts. I have already spoke with Compcams and TPIS. With all the info and weights I had Compcams recommended the cam in the list below. I have been doing some serious research even picked up a few reference books. Now this is not my first time building a motor but it is my first time building (per-say) a fuel injection system. If you see something wrong or I am missing please don’t flame me as this is my first initial list of something new. Input is always welcome.

I have read some stuff here on the forums and I would really like to avoid having to write cusom .BIN files like I have seen here. As much as I know I need to get it running. Data log with Tunerpro send that info off to someone and they will burn a proper EPROM.
