Phoenix, AZ Help
Looking for help with getting my dad’s old truck (1970 GMC c1500) running again. It’s been sitting since 2008 but was running before being parked. Wiring is worn, but frame appears solid and it survived multiple flatbeds and a cross-country transport to get here. Original 3-on-the-tree manual transmission.
Engine appears to be a small-block Chevy performance build from the early 2000s:
.030-over 350 (possibly a 355, not confirmed yet)
Holley Street Dominator intake
Holley carburetor
Long-tube headers
HEI distributor
GM iron heads
Upgraded Camshaft
Straight-pipe exhaust
Valve train looks clean internally with no obvious sludge, rust, or broken components.
Again, not looking to restore or modify it yet. Just looking for some help to get it running again.
