Fits for Chevy Small Block SBC 262 265 267 283 302 305 307 327 350 400 V8 Engines
The open air space from the Air-Gap design separates the runners from the heat of the lifter-valley cover. So, the air/fuel mixture stays cooler all the way to the heads, which produces a denser charge for more power. Runners are tuned to move the power band 1,000 rpm higher than Air-Gap manifolds, from idle to 5,500 rpm up to 1,500 to 6,500 rpm.
