Fits for Chevy BBC 396 402 427 454 Engine
Product Features:
- Performer RPM Air-Gap intake manifolds incorporate race-winning technology that's been used on Victor Series competition intakes for years. 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 Performer Air-Gap manifolds, from idle to 5,500 rpm up to 1,500 to 6,500 rpm.
Compatible with:
- 1965-1970 V8 6.5L 396
- 1970-1972 V8 6.6L 402
- 1966-1969 V8 7.0L 427
- 1970-2000 V8 7.4L 454
Choosing the suitable intake manifold will improve your engines performance and your driving experience.

This intake fits my Mark IV 454 big block with 346236 heads. Now there are a few of the bolt holes that will not fit the bolt and socket without hitting the intake or scratching it. Appears to be a casting flaw. Overall it fits and works as desired. Will be purchasing a named brand one later.
