We experimented with timing (eventually settling on 35 degrees) and minor jetting to the rebuilt Holley before letting the hammer fly. With a safe air/fuel mixture in the high 12s, the 350 eventually pumped out 407 hp at 5,900 rpm and 410 lb-ft of torque at 4,500 rpm. We had officially reached our goal of producing 400 hp.
The final bill for our 400hp build up checked in at $1,155, including the cost of the motor. We were excited about the 400hp peak number, but what really made us happy was the fact that this low-buck motor produced over 400 lb-ft of torque from 3,700-5,200 rpm. Even down at 3,000 rpm, Chump Change churned out 372 lb-ft of torque. Yes, we went $155 over budget, but the result is still affordable for most any enthusiast.
