Summit Racing® and HorsePower TV have teamed up to show you how to find the true power potential in your street small block. We have done our homework to bring you another segment in a series of carefully chosen, matched components designed for streetable horsepower and torque. The Bang for the Buck Small Block Chevy Test HP0704 started with a solid foundation on HorsePower TV's 290 hp 350 Chevy "mule" motor. We then added our Summit Street & Strip® Stage 1 cast aluminum dual-plane intake manifold. This intake is perfect for the street, with a high-flow runner design and advertised rpm range of idle to 6,000 rpm. For carburetion, we went with a classic in our remanufactured 750 cfm Summit® Quadrajet. Featuring an electric choke, this carburetor will provide great drivability and performance. No performance upgrade is complete without a new bump stick, so we added one of our Summit® performance camshaft and lifter kits. With specs like 0.465 in. lift, 224 duration at 0.050 in. lift, and 114 degrees of lobe separation, this cam will provide a good increase in power and torque throughout the rpm range and still provide enough vacuum to run accessories like power brakes. The last piece to this puzzle was our Summit® True Roller timing set. Featuring rugged double-row true-roller chains and steel crank and cam sprockets, our timing sets will deliver accurate and reliable cam timing. So, how did this combo stack up on HorsePower TV's DTS PowerMark engine dyno? The dyno run resulted in a peak torque of 345 ft.-lbs. at 3,800 rpm, and 304 hp at 5,500 rpm. That's an extra 19 ft.-lbs. of torque and 14 hp. What's most impressive is the consistent increase in torque throughout the powerband from 2,500 rpm to the horsepower peak at 5,500 rpm, making this combo a true street performer!
