1979 Chevy Silverado 355 Twin Turbo

Post by hiperf402 » Sun Oct 17, 2010 5:31 pm

My current project is a 1979 Chevy Silverado Pickup 355 Twin Turbo Intercooled V8.


Engine:
SBC 350 bored .030. 4 valve relief flat top pistons. 8.5-9:1 compression
Summit Sum-1105 cam
Stock heads with 1.96 int 1.60 exh stainless valves
TPI intake with FAST 60 lb/hr injectors
STR Cast iron t3/t4 manifolds with T04E Hybrid Turbos .63 A/R Turbine .60 A/R Compressor
38mm wastegates set @ 8 psi with manual controller to be installed for more boost :D
2 1/2 inch hot side tubing feeding 2 in 1 out intercooler with 3 inch cold tubing
OBX 700 Hp fuel pump, stock FPR

Electronics:
Megasquirt II with PCB v3.0 running B&G 2.890 firmware
8 pin hei module
Tech Edge wideband oxygen sensor. planning for duals though.

Current status as of today is that I still need to wire and install o2 sensor, vacuum check valves and blow-off valves, manual boost controller and map tubing. I had running very briefly because I couldn't contain myself to wait. I hope pics turn out.
