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.
Engine short block: 99 5.7 Vortec
Heads: ‘ 99 L31 heads with valve springs redone to .520”lift provided heads are good.
Cam: compcams XR264HR #8-501-08
GMPP Roller lifters #12499225
Melling double roller timing chain
Est 9.5:1 CR
’89 Tuned Port Injection
Stock runners
Stock TB
Scoggin dickey TPI Vortec intake #SD3816
24lb blue top injectors
BBK Adjustable fuel psi regulator #BBK-1714
MAF Sensor
1227165 ECM
New stand alone harness from Howell EFI
All new sensors.
Other stuff
ALDLdorid app

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.
