400 to 512 Build

I like those HP numbers... I'll be racing down south in good air at an outlaw track.. One part at a time but I'll get there.. I'd have to spend a crap load of cash anyway to reach the performance level I want out of the 383 so why not just spend a little more and go BIG...

a conservative estimate is 15% HP loss here at Bandimere...... Pro Stock runs much higher RPM here and still is 5/10th slower, TF and FC way overdrive thier blowers....
