Chevy 350 Engine Build - The Chump Change Challenge

In These Recessionary Times, Can We Deliver 400 Hp For Under A Thousand Bucks?

By Richard Holdener, Photography by Richard Holdener

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.
