| + | One big improvement to the Chevy inline 250 engine's head is to install an exhaust port "lump". For years, these was a one-off, hand made piece that was 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] has designed a lump and can supply all the necessary tools and info to install it. It is a cast and machined piece of iron that fits into the exhaust port floor to vastly improve flow. | ||
