With some careful planning we just woke the monster. TBI 350 I just finished building, took a 4bolt main block, roller cam and rockers, a set of eq heads(vortec chamber, tbi intake) hit the dyno and made 299.6 hp and 370 ft lbs of torque using the stock 350 tbi unit, with some modifications. Big block injectors, pod spacer, fuel pressure regulator/spring. Running 12psi of fuel pressure.
I feel like a bunch of power was left on the table, the tbi unit seems to be the cork. At 4500 rpm it started pulling 1.5” of vacuum and by 5000 it was almost 2”. Wondering if I switched to the the big block throttle body unit if I would gain anything worthwhile or just wasting time. Aside from that it runs just awesome.
