My thoughts exactly. There is a local racer here who runs a 306cid with a 300 shot and pulls 10.3's. A guy I used to work with built a 302 cid twin turbo and ran a 9.6. A twin turbo mustang is a rare sight. I'd rather go low rpm for longevitys sake. Especially since its a home built project. That would just suck to grenade your motor on the first outing because of a simple "newbie" mistake.
