The deck height of the Chevy 230 and 250 inline 6 engines is shorter than the 292 inline 6 engine. That means the pushrod cover is shorter on those engines than the 292 Chevy 6. | The deck height of the Chevy 230 and 250 inline 6 engines is shorter than the 292 inline 6 engine.

So it comes as no surprise that improving the intake port flow will help power. A big improvement to the Chevy inline 250 cylinder head is to install an intake port "lump". For years, these were one-off, hand-made pieces that were quite a chore to fabricate and mount. Some were better than others, and some were worse than nothing. Nowadays, [http://t6racing.org/index.html T6 Racing] and [http://www.12bolt.com/home Autowerks] have designed a lump kit and can supply all the necessary tools and info to install it. It is cast and machined pieces of metal that fit onto the intake port floors to vastly improve flow. | So it comes as no surprise that improving the intake port flow will help power.

Using the earlier head with the detachable intake from a 230 or 250 inline Chevy 6 offers a much better platform. | Using the earlier head with the detachable intake from a 230 or 250 inline Chevy 6 offers a much better platform. | ||
