Finally, my first 360 and goals for it! I'll be asking a lot of questions.

Nice. Port matching may help some. I tagged IQ52 for you, he's a true master builder, listen to his advice whenever chimes in.

If I may ask, why the switch from the 273?
Thanks. I want more bottom end torque. The 273 is all about high winding and I cant really use that on the street.
