[QUOTE="na svt, post: 9523402, member: 35346"] Short runners don't offer great peak power gains but the gains after peak (6500-7000)are in the 20-30rwhp range. So, if you shift at below 6900 you won't be any quicker in the 1/4. There are also some losses down low with a short runner. With that, it's possible to get 370rwhp (dynojet SAE) with 03/04 heads and a ported intake. This can be done with cams that can use stock valve springs. Actual gains depend a lot on engine condition, gears, dyno used, and the aggressiveness of the tune. [/QUOTE]
