So I am looking into converting a 350cu. to throttle body fuel injection. I know Holley and FAST make kits, so wondering if either one is better than the other or is there another manufacturer out there that is better ? My understanding is the motor is pretty much stock aside from a mild cam. It currently has a RPM intake, so hoping to use it. Inline fuel pump over in tank ? The gas tank was custom built to fit into a small space, and whom ever built it only installed a 1/4" fuel line, so I am also thinking I may need to fab a 3/8" fuel line ?
